Intel Core Ultra 2-series "Arrow Lake-S" Desktop Features 4 Xe-core iGPU, No Island Cores

Over the weekend, there have been a series of leaks from sources such as Golden Pig Upgrade, and High Yield YT, surrounding Intel's next-generation desktop processor, the Core Ultra 2-series "Arrow Lake-S." The lineup is likely to continue the new client processor naming scheme Intel introduced with the Core Ultra 1-series "Meteor Lake" on the mobile platform. "Arrow Lake-S" is rumored to debut the new Socket LGA1851, which retains cooler-compatibility with LGA1700. Although Intel has nucleated all I/O functions of the traditional PCH to "Meteor Lake," making it a single-chip solution on the mobile platform; and although the mobile "Arrow Lake" will continue to be single-chip; the desktop "Arrow Lake-S" will be a 2-chip solution. This is mainly because the desktop platform demands a lot more PCIe lanes, for a larger number of NVMe storage devices, or high bandwidth devices such as Thunderbolt and USB4 hubs, etc.

Another key finding in this latest series of leaks, is that unlike "Meteor Lake," the desktop "Arrow Lake-S" will do away with low-power island E-cores located in the SoC tile of the processor. All CPU cores are located in the Compute tile, which is expected to be built in the Intel 20A foundry node—the company's first node to implement GAAFETs (nanosheets), with backside power delivery; as well as an advanced 2nd generation EUV lithography. Intel's 1st Gen EUV is used on the current FinFET-based Intel 4 and Intel 3 foundry nodes.

Chinese Loongson 3A6000 CPU Matches Intel "Raptor Lake" IPC

The Chinese chipmaker Loongson has launched its newest desktop processors, the 4-core, 8-thread 3A6000 series, based on the company's LoongArch microarchitecture. We have previously reported that the company wants to match Intel's "Willow Cove" and AMD's Zen 3 instruction per clock (IPC) levels with its 3A6000 CPU series, and today we have the first preview of the performance. Powered by the LA664 cores, 3A6000 is built on a 14/12 nm manufacturing process, with clock speeds going from 2.0 to 2.5 GHz and power consumption of up to 50 Watts. It features 256 KB of L2 cache and 16 MB of L3 cache in total.

While several hardware partners are announcing new Loongson-powered solutions, ASUS China's "Uncle Tony" managed to get his hands on one of them and overclocker the CPU to 2.63 GHz on air cooling. In overclocking tests using liquid nitrogen cooling, a 3A6000 processor reached 3.0 GHz, though there are indications that there is still overhead. In standard out-of-the-box configuration, the 3A6000 performs similarly to Intel's Core i3-10100 four-core CPU, an achievement for Loongson but still behind Intel's latest offerings that clock nearly twice as high. This rapid development of Loongson IP has led to a massive performance increase, matching the IPC of modern CPUs. We are still left to see more information about these 3A6000 series SKUs; however, early benchmarks suggest a significant improvement. You can see the CPU benchmarks below, which include UnixBench and SPEC CPU 2006.

Enablement Continues for Chinese Loongson 3A6000 CPUs Poised to Compete with Intel Willow Cove and AMD Zen 3

Chinese company Loongson, specializing in creating processors for usage in mainland China, has been steadily working on enabling its next-generation Loongson 3A6000 CPUs. Aiming to provide the performance level of Intel Willow Cove and AMD Zen 3, these new CPUs will use Loongson's custom LoongArch Instruction Set Architecture (ISA) with a new set of 64-bit superscalar LA664 cores. Today, thanks to the report from Phoronix, we find out that Loongson has submitted some Linux patches that enable the upcoming 3A6000 CPUs to work with Linux-based operating systems at launch. Interestingly, as the new CPU generation gets closer to launch, more Linux kernel patches begin to surface.

Today's kernel patches focus on supporting the hardware page table walker (PTW). As PTW can handle all fast paths of TLBI/TLBL/TLBS/TLBM exceptions by hardware, software only needs to handle slow paths such as page faults. Additionally, in the past, LoongArch utilized "dbar 0" as a complete barrier for all operations. However, this full completion barrier severely impacted performance. As a result, Loongson-3A6000 and subsequent processors have introduced various alternative hints. Loongson plans to ship samples to select customers in the first half of 2023, so we could see more information surfacing soon.

Latency Increase from Larger L2 Cache on Intel "Raptor Cove" P-core Well Contained: Report

According to an investigative report by "Chips and Cheese," the larger L2 caches in Intel's 13th Gen Core "Raptor Lake-S" doesn't come with a proportionate increase in cache latency, and Intel seems to have contained the latency increase well. "Raptor Lake-S" significantly increases L2 cache sizes over the previous generation. Each of its 8 "Raptor Cove" P-cores has 2 MB of dedicated L2 cache, compared to the 1.25 MB with the "Golden Cove" P-cores powering the current-gen "Alder Lake-S," which amounts to a 60 percent increase in size. The "Gracemont" E-core clusters (group of four E-cores), sees a doubling in the size of the L2 cache that's shared among the four cores in the cluster, from 2 MB in "Alder Lake," to 4 MB. The last-level L3 cache shared among all P-cores and E-core clusters, sees a less remarkable increase in size, from 30 MB to 36 MB.

Larger caches have a direct impact on performance, as more data is available close to the CPU cores, sparing them a lengthy fetch/store operation to the main memory (RAM). However, making caches larger doesn't just cost die-area, transistor-count, and power/heat, but also latency, even though L2 cache is an order of magnitude faster than the L3 cache, which in turn is significantly faster than DRAM. Chips and Cheese tracked and tabulated the L2 cache latencies of past Intel client microarchitectures, and found a generational increase in latencies with increasing L2 cache sizes, leading up to "Alder Lake." This increase has somehow tapered with "Raptor Lake."

Loongson Claims its CPU IPC Will Match AMD Zen 3 and Intel Willow Cove by 2023

Chinese PC and server processor designer Loongson claims that its upcoming processor microarchitecture will offer an IPC that matches that of the AMD "Zen 3" (or slightly faster than Intel "Willow Cove."). The Godson 3A6000 processors are based on the LA664 microarchitecture, which Loongson has compared with off-the-shelf AMD Ryzen 5 5600G and Intel Core i7-1165G7 processors, on several cross-platform benchmarks, and claimed to have obtained comparable single-threaded performance.

The LA664 microarchitecture is based on Loongson's in-house ISA, and unlike Zhaoxin processors, aren't x86-64 compatible. Loongson processors are generally bought in bulk by the Chinese government and military, to run servers and workstations that are completely devoid of foreign hardware, for security reasons. The custom machine architecture is paired with a compatible *nix operating system that's equally built from the ground-up. 2023 will see Loongson launch 3A6000 processor as a multi-chip module with 32 CPU cores.

Intel Launches 10nm "Tiger Lake" Desktop Processors

Intel is likely preparing to launch its 10 nm "Tiger Lake" processor on the desktop platform. momomo_us discovered the existence of at least four new processor SKUs in Intel's ARK pages. At least one of these is marked as a desktop chip. What isn't clear, is whether these are Socket LGA1200 chips, like "Rocket Lake-S," or whether these are FC-BGA chips that have been adapted for specific desktop use-cases, such as NUCs. At the heart of these chips is the new 10 nm "Tiger Lake" 8-core/16-thread silicon, which packs 8 "Willow Cove" CPU cores, 24 MB of shared L3 cache, and a Gen12 Xe LP iGPU that has 32 EUs.

The common theme with the processor model numbering with these SKUs is the brand extension "B," next to model numbers we commonly associate with "Rocket Lake-S" SKUs. Another commonality is TDP. All four SKUs are marked as 65-Watt chips, including the part that has an unlocked multiplier. The lineup is led by the Core i9-11900KB, an 8-core/16-thread chip with Thermal Velocity Boost frequency of up to 5.30 GHz, and base frequency of 3.30 GHz. The Core i7-11700B lacks an unlocked multiplier, but interestingly features TVB, and retains the core-count and cache amount of the i9-11900KB. It is clocked at speeds of up to 5.30 GHz. The Core i5-11500B is a 6-core/12-thread part, with 12 MB of L3 cache, and the same 5.30 GHz boost, set via TVB. The Core i3-11100B is a 4-core/8-thread part with 8 MB L3 cache, and is likely based on the 4-core "Tiger Lake" die, with its iGPU cut down. The clocks remain the same. It remains to be seen how Intel markets these parts.

Intel "Sapphire Rapids" Xeon Processors Use "Golden Cove" CPU Cores, Company Clarifies in Linux Kernel Dev E-Mail Chain

Intel's upcoming Xeon "Sapphire Rapids" processors which debut in the second half of 2021, will feature up to 80 "Golden Cove" CPU cores, and not the previously rumored "Willow Cove." This was clarified by an Intel developer in a Linux Kernel code e-mail chain. "Golden Cove" CPU cores are more advanced than the "Willow Cove" cores found in current-generation Intel products, such as the client "Tiger Lake" processors. Intel stated that "Golden Cove" introduces an IPC gain over "Willow Cove" (expressed as "ST perf"), increased AI inference performance from an updated GNI component, "network and 5G perf," which is possibly some form of network stack acceleration, and additional security features.

Over in the client segment, the 12th Gen Core "Alder Lake" processor debuts a client variant of "Golden Cove." The "Alder Lake-S" silicon features eight "Golden Cove" cores serving as the "big" performance cores, next to eight "little" low-power "Gracemont" cores. The client- and server implementations of "Golden Cove" could differ mainly in the ISA, with the client chip receiving a slightly skimmed AVX-512 and DLBoost instruction-sets, with only client-relevant instructions. The server variant, in addition being optimized for a high core-count multi-core topology; could feature a more substantial AVX-512 and DLBoost implementation relevant for HPC use-cases.

Intel Announces 11th Gen Core "Tiger Lake-H" Mobile Processors

Intel today announced the 11th generation Core "Tiger Lake-H" mobile processors for notebooks of conventional thickness, gaming notebooks, and mobile workstations. This is the first scale-up of the "Tiger Lake" microarchitecture, with the introduction of a brand new die that has up to 8 "Willow Cove" CPU cores. These processors typically come with TDP of 35-45 W, but the flagship part ships with TDP as high as 65 W. Unlike "Rocket Lake," this chip is built on Intel's latest 10 nm SuperFin silicon fabrication process. With it, Intel is announcing ten processor SKUs—five each for the consumer and commercial notebook market segments. These span across the Core i9, Core i7, and Core i5 brand extensions.

The 10 nm "Tiger Lake-H" silicon measures roughly 190 mm², and has several changes compared to the 4-core "Tiger Lake-U" silicon the company debuted the 11th Gen with. The biggest change is the CPU core count of 8. This lets it not only achieve parity with AMD in mobile CPU core counts, but also purportedly beat it on the back of a higher IPC. Each of these 8 "Willow Cove" cores has 1.25 MB of dedicated L2 cache, and share 24 MB of L3 cache. You get the same "Willow Cove" ISA as the "Tiger Lake-U," including AVX-512 and DLBoost. Next up, the chip features an integrated graphics based on the Gen12 Xe LP graphics architecture, only that the execution units have reduced to just 32 on this silicon, compared to 96 on the 4-core Tiger Lake-U. The new chip enjoys a bigger power budget to run the iGPU at higher clock speeds. There is also a 20-lane PCI-Express Gen 4.0 interface, and a dual-channel DDR4 memory controller.

11th Gen Intel Core-H Specs Leaked: 8-core "Tiger Lake" a Reality

Intel's fabled 8-core "Tiger Lake-H" silicon built on the 10 nm SuperFin process, is close to reality. The company's upcoming 11th Gen Core "Tiger Lake-H" processors for performance- and gaming notebooks, leverages this die. An HD Tecnologia report leaks alleged company slides from Intel that detail the processor line up and feature-set. To begin with, the 11th Gen Core-H series processors come in core-counts ranging from 4-core/8-thread, to 6-core/12-thread, and 8-core/16-thread. Look at the embargo date on the leaked slides, one could expect a formal launch as close as May 11, 2021.

The 10 nm SuperFin "Tiger Lake-H" silicon features 8 "Willow Cove" CPU cores, and an updated iGPU based on the company's latest Gen12 Xe LP graphics architecture. Each of the eight CPU cores has 1.25 MB of L2 cache, and they share a massive 24 MB of L3 cache. The Gen12 Xe LP iGPU only has 32 execution units (EUs), according to the slides, 1/3rd those of the 96 EUs on the "Tiger Lake-U." The uncore component is also updated, now featuring dual-channel DDR4-3200 native support, and a 28-lane PCI-Express 4.0 root-complex. 16 of these lanes are wired out as PEG (PCI-Express Graphics), four as a CPU-attached NVMe slot, and eight toward the 8-lane DMI 3.0 chipset bus.

Intel Rocket Lake-S Lands on March 15th, Alder Lake-S Uses Enhanced 10 nm SuperFin Process

In the latest round of rumors, we have today received some really interesting news regarding Intel's upcoming lineup of desktop processors. Thanks to HKEPC media, we have information about the launch date of Intel's Rocket Lake-S processor lineup and Alder Lake-S details. Starting with Rocket Lake, Intel did not unveil the exact availability date on these processors. However, thanks to HKEPC, we have information that Rocket Lake is landing in our hands on March 15th. With 500 series chipsets already launched, consumers are now waiting for the processors to arrive as well, so they can pair their new PCIe 4.0 NVMe SSDs with the latest processor generation.

When it comes to the next generation Alder Lake-S design, Intel is reported to use its enhanced 10 nm SuperFin process for the manufacturing of these processors. This would mean that the node is more efficient than the regular 10 nm SuperFin present on Tiger Lake processors, and some improvements like better frequencies are expected. Alder Lake is expected to make use of big.LITTLE core configuration, with small cores being Gracemont designs, and the big cores being Golden Cove designs. The magic of Golden Cove is expected to result in 20% IPC improvement over Willow Cove, which exists today in Tiger Lake designs. Paired with PCIe 5.0 and DDR5 technology, Alder Lake is looking like a compelling upgrade that is arriving in December of this year. Pictured below is the LGA1700 engineering sample of Alder Lake-S processor.

Intel Xeon "Sapphire Rapids" LGA4677-X Processor Sample Pictured

Here are some of the first pictures of the humongous Intel Xeon "Sapphire Rapids-SP" processor, in the flesh. Pictured by YuuKi-AnS on Chinese micro-blogging site bilibili, the engineering sample looks visibly larger than an AMD EPYC. Bound for 2021, this processor will leverage the latest generation of Intel's 10 nm Enhanced SuperFin silicon fabrication node, the latest I/O that include 8-channel DDR5 memory, a large number of PCI-Express gen 5.0 lanes, and ComputeXpress Link (CXL) interconnect. Perhaps the most interesting bit of information from the YuuKi-AnS has to be the mention of an on-package high-bandwidth memory solution. The processors will introduce an IPC uplift over "Ice Lake-SP" processors, as they use the newer "Willow Cove" CPU cores.

Intel "Rocket Lake-S" Die Annotated

Intel is betting big on an 8-core processor to revive its gaming performance leadership, and that chip is the 11th Generation Core "Rocket Lake-S," coming this March. In its 2021 International CES online event, Intel disclosed more details about "Rocket Lake-S," including the first true-color die-shot. PC enthusiast @Locuza_ on Twitter annotated the die for your viewing pressure. For starters, nearly half the die-area of the "Rocket Lake-S" is taken up by the uncore and iGPU, with the rest going to the eight "Cypress Cove" CPU cores.

The "Cypress Cove" CPU core is reportedly a back-port of "Willow Cove" to the 14 nm silicon fabrication node, although there are some changes, beginning with its cache hierarchy. A "Cypress Cove" core is configured with the same L1I and L1D cache sizes as "Willow Cove," but differ with L2 and L3 cache sizes. Each "Cypress Cove" core is endowed with 512 KB of dedicated L2 cache (which is a 100% increase from the 256 KB on "Skylake" cores); but this pales in comparison to the 1.25 MB L2 caches of "Willow Cove" cores on the "Tiger Lake-U" silicon. Also, the L3 cache for the 8-core "Rocket Lake-S" die is 16 MB, spread across eight 2 MB slices; while the 4-core "Tiger Lake-U" features 12 MB of L3, spread across four 3 MB slices. Each core can address the whole L3 cache, across all slices.

Intel 11th Gen Core "Rocket Lake" Desktop TDP Values Surface

Intel's 11th Gen Core "Rocket Lake-S" desktop processors could feature similar TDP values to their 10th Gen "Comet Lake-S" predecessors, according to Momomo_us. Intel is preparing to give the Unlocked "K" and "KF" SKUs a TDP rating of 125 W, while the locked non-K models feature 65 W rating. The lineup is led by the 8-core/16-thread Core i9-11900K, followed by the locked i9-11900 and iGPU-devoid i9-11900F; the slightly slower 8-core/16-thread Core i7-11700K, followed by the i7-11700KF, i7-11700, and i7-11700F; and the 6-core/12-thread i5-10600K and its derivatives.

The 11th Gen Core desktop processor series arrives in Q1 2021, and is based on the 14 nm "Rocket Lake-S" silicon, and built into the Socket LGA1200 package, with backwards compatibility with Intel's 400-series chipset motherboards, and native support for the Intel 500-series. The "Rocket Lake-S" die is rumored to feature up to 8 "Cypress Cove" CPU cores, a dual-channel DDR4 memory controller, a 24-lane PCI-Express 4.0 root complex, and an updated Gen12 iGPU based on the Xe LP graphics architecture. The "Cypress Cove" CPU cores are reportedly 14 nm back-ports of the "Willow Cove" cores, and feature a double-digit percent IPC increase over the "Skylake" cores.

Apple M1 Beats Intel "Willow Cove" in Cinebench R23 Single Core Test?

Maxon ported the its latest Cinebench R23 benchmark to the macOS "Big Sur" Apple M1 platform, and the performance results are groundbreaking. An Apple M1-powered MacBook Pro allegedly scored 1498 points in the single-core Cinebench R23 test, beating the 1382 points of the Core i7-1165G7 reference score as tested by Maxon. These scores were posted to Twitter by an M1 MacBook Pro owner who goes by "@mnloona48_" The M1 chip was clocked at 3.10 GHz for the test. The i7-1165G7 uses Intel's latest "Willow Cove" CPU cores. In the same test, the M1 scores 7508 points in the multi-core test. If these numbers hold up, we can begin to see why Apple chose to dump Intel's x86 machine architecture in favor of its own Arm-powered custom silicon, as the performance on offer holds up against the highest IPC mobile processors in the market.

Intel 11th Generation Core Tiger Lake-H Processor Appears

Intel has launched its Tiger Lake-U lineup of products back in September, with the availability of the first products in October. The launched lineup was part of the "U" variant of ultra-portable devices that stretched only to four core, eight threaded configurations. However, given that the new competitor in mobile space, AMD, has a wide portfolio of offerings that are coming with up to 8C/16T variants, Intel needs a proper response to that. Despite having a better single-threaded performance, the multi-threaded capability of the Ryzen 4000 series is delivering better performance. Thanks to the popular hardware leaker, TUM APISAK, we have the first appearance of Intel's 11th generation Tiger Lake-H processor.

Appearing in Userbenchmark, the processor was tested on a platform codenamed "Insyde TigerLake". The processor was spotted running 8 cores and 16 threads, at the average frequency of 2.75 GHz. This is only an engineering sample, meaning that these clocks do not represent the final frequencies of the processor. As a reminder, Intel's Tiger Lake CPU is a Willow Cove based design manufactured on Intel's 10 nm SuperFin silicon node. We are yet to see the capabilities of the new node and how the chip performs once the reviews arrive.

Intel Confirms Rocket Lake-S Features Cypress Cove with Double-Digit IPC Increase

Today, Intel has decided to surprise us and give an update to its upcoming CPU lineup for desktop. With the 11th generation, Core CPUs codenamed Rocket Lake-S, Intel is preparing to launch the new lineup in the first quarter of 2021. This means that we are just a few months away from this launch. When it comes to the architecture of these new processors, they are going to be based on a special Cypress Cove design. Gone are the days of Skylake-based designs that were present from the 6th to 10th generation processors. The Cypress Cove, as Intel calls it, is an Ice Lake adaptation. Contrary to the previous rumors, it is not an adaptation of Tiger Lake Willow Cove, but rather Ice Lake Sunny Cove.

The CPU instruction per cycle (IPC) is said to grow in double-digits, meaning that the desktop users are finally going to see an improvement that is not only frequency-based. While we do not know the numbers yet, we can expect them to be better than the current 10th gen parts. For the first time on the Intel platform for desktops, we will see the adoption of PCIe 4.0 chipset, which will allow for much faster SSD speeds and support the latest GPUs, specifically, there will be 20 PCIe 4.0 lanes coming from the CPU only. The CPU will be paired with 12th generation Xe graphics, like the one found in Tiger Lake CPUs. Other technologies such as Deep Learning Boost and VNNI, Quick Sync Video, and better overclocking tuning will be present as well. Interesting thing to note here is that the 10C/20T Core i9-10900K has a PL1 headroom of 125 W, and 250 W in PL2. However, the 8C/16T Rocket Lake-S CPU also features 125 W headroom in PL1, and 250 W in PL2. This indicates that the new Cypress Cove design runs hotter than the previous generation.

Intel Confirms Q1-2021 Launch of 11th Gen Core "Rocket Lake"

Intel VP and GM of Client Computing Group Desktop, Workstations and Gaming, John Bonini, in a Medium blog post renewed the company's commitment to gaming, by announcing the tentative launch timeline of the company's next-generation Core desktop processors. The 11th Gen Intel Core "Rocket Lake" processors will launch in Q1-2021. "I'm also happy to confirm that the next generation 11th Gen Intel Core desktop processors (codenamed "Rocket Lake") is coming in the first quarter of 2021 and will provide support for PCIe 4.0. It'll be another fantastic processor for gaming, and we're excited to disclose more details in the near future," he said.

It's important to note the timing of this post. AMD later today (8th October) will announce its next-generation Ryzen processors based on the "Zen 3" microarchitecture, and is widely expected to push the IPC envelope even further. This would mean that from the near-parity AMD enjoys with Intel's "Skylake" based "Comet Lake" processor, AMD would begin to achieve a clear IPC lead over Intel for the first time in over 15 years. An alleged Intel 500-series chipset motherboard launch-related slide leaked earlier this week pins the chipset's launch in mid-March 2021. Given that Intel tends to launch new processors and chipsets in tandem, this would possibly put the launch of "Rocket Lake" toward the very end of Q1-2021. "Rocket Lake" is expected to introduce Intel's first IPC gains in the desktop segment since 2015. The chips use new "Cypress Cove" CPU cores, which are a 14 nm backport of "Willow Cove."

Intel 11th Gen Core "Tiger Lake" & Xe Graphics Launch Event: Live Blog

Intel today launches its 11th Gen Core "Tiger Lake" mobile processors that introduce several new technologies on the backs of new IP. As described in the Architecture Day, "Tiger Lake" is built on the 10 nm SuperFin process, and combines new "Willow Cove" CPU cores with the first commercial debut of the Xe Gen12 graphics architecture that Intel is betting big on, to make a stab at the consumer graphics and scalar compute markets. Join us in this live-blog.

Update 16:00 UTC: GB (Gregory Bryant, EVP Client), leads the event from the comfort of his home.
Update 16:04 UTC: Here it is, the "world's best processor for thin and light laptops. You'll notice that like most Intel U-segment chips, this is an MCM of the processor and PCH die. Intel bases its "world's best" claims on a per-segment basis.

Intel Launches World's Best Processor for Thin-and-Light Laptops: 11th Gen Intel Core

Intel today unleashed a new era of laptop performance with the launch of its next-generation mobile PC processors and the evolution of its broad ecosystem partnerships that are propelling the mobile PC industry forward. New 11th Gen Intel Core processors with Intel Iris Xe graphics (code-named "Tiger Lake") are the world's best processors for thin-and-light laptops with unmatched capabilities for real-world productivity, collaboration, creation, gaming and entertainment across Windows and ChromeOS-based laptops.

Leveraging Intel's new SuperFin process technology, 11th Gen Intel Core processors optimize power efficiency with leading performance and responsiveness while running at significantly higher frequencies versus prior generations. More than 150 designs based on 11th Gen Intel Core processors are expected from partners including Acer, ASUS, Dell, Dynabook, HP, Lenovo, LG, MSI, Razer, Samsung and others.

Intel "Willow Cove" Core, Xe LP iGPU, and "Tiger Lake" SoC Detailed

A lot is riding for Intel on its 11th Gen Core "Tiger Lake" system-on-chip (SoC), which will launch exclusively on mobile platforms, hoping to dominate the 7 W thru 15 W ultraportable form-factors in 2020, while eventually scaling up to the 25 W thru 45 W H-segment form-factors in 2021, with a variant that is rumored to double core-counts. The chip is built on Intel's new 10 nm SuperFin silicon fabrication node that enables a double digit percentage energy efficiency growth over 10 nm, allowing Intel to significantly dial up clock speeds without impacting the power envelope. The CPU and iGPU make up the two key components of the "Tiger Lake" SoC.

The CPU component on the "Tiger Lake" processors that launch in a few weeks from now features four "Willow Cove" CPU cores. Coupled with HyperThreading, this ends up being a 4-core/8-thread setup, although much of Intel's innovation is in giving these cores significant IPC increases over the "Skylake" core powering "Comet Lake" processors, and compared to the "Sunny Cove" cores powering "Ice Lake" a minor IPC (although major net performance increase from clock speeds). The "Willow Cove" CPU core appears to be a derivative of the "Sunny Cove" core, designed to take advantage of the 10 nm SuperFin node, along with three key innovations.

Intel Core i3-1115G4 Tiger Lake CPU Surfaces on SiSoftware Sporting An Incredible Base Clock

Database spelunker TUM_APISAK has brought to the surface another revealing entry regarding Intel's upcoming Tiger Lake CPUs. Discovered in SiSoftware's database entries, the Intel Core i3-1115G4 has reared its head sporting a mightily impressive base core clock set at 3.0 GHz. Compare this to the Ice Lake-based Core i3-1005G1, which while making use of the 10 nm process itself, only managed to run on a 1.2 GHz base clock. This increase speaks to Intel's refinement of the 10 nm manufacturing process (even sporting its well-known woes) and the usage of the new Willow Cove architecture core that will power the i3-1115G4.

Whilst still being a 2-core, 4-thread processor (ehrm), the new i3-1115G4 based on Tiger Lake sports a number of improvements on both its CPU and GPU core design. The new architectural improvements baked into Willow Cove are aided by an L3 cache boost from 4 MB to 6 MB, and its GPU is expected to make use of Intel's Xe graphics, featuring 96 EUs (compared to the 64 EUs in Ice Lake's 12th Gen graphics). It remains to be seen exactly how competitive Tiger Lake will be compared to AMD's current (and future) Ryzen offerings, but these are some encouraging leaks.

Intel "Tiger Lake" Launch Slated for September 2, Raja Koduri to Update Xe Progress Mid-August

Intel will launch its 11th Generation Core "Tiger Lake" mobile processors on September 2. The company sent out invites to a "virtual event" to be held on that date, which will be webcast to the public. On that day, several major notebook manufacturers are expected to unveil their next-generation devices based on the new processors. "Tiger Lake" is an important product launch for Intel as it marks the commercial debut of its ambitious Xe graphics architecture as the chip's Gen12 integrated graphics solution. In related news, Intel's chief architect for Xe, Raja Koduri, is expected to lead a webcast on August 13, where he will provide an update on his team's work.

The processors also debut the "Willow Cove" CPU cores that offer increased IPC over current "Sunny Cove" and "Skylake" cores, which will play a big role in closing the performance gap against the 8-core "Zen 2" processors by AMD based on the "Renoir" silicon. "Tiger Lake" is also expected to be one of the final front-line mobile processors by Intel to feature only one kind of CPU cores, as the company is expected to go big on Hybrid core technology with its future microarchitectures.

Intel to Clock "Rocket Lake-S" High, Evidence of an ES with 5.00 GHz Boost

Intel's 11th Generation Core "Rocket Lake-S" desktop processors in the LGA1200 package could come with clock speeds that are of the norm these days. Intel appears unwilling to dial down clock speeds in the wake of increased IPC with the new generation "Cypress Cove" CPU cores that drive these processors. Twitter handle "leakbench," which tracks interesting Geekbench results, fished out a database listing for a "Rocket Lake-S" engineering sample with clock speeds of 3.40 GHz base, and 5.00 GHz boost.

The listing has all the telltale signs of "Cypress Cove," such as 48 KB L1D cache, 512 KB per core L2 cache, and 16 MB shared L3 cache for this 8-core/16-thread chip. "Cypress Cove" is rumored to be to be a back-port of Intel's "Willow Cove" CPU core design from its original 10 nm+ node to the 14 nm++. VideoCardz compared this "Rocket Lake-S" ES benchmark result to that of a retail Core i7-10700K, and found its single-threaded performance to be roughly 6.35 percent higher despite a 200 MHz clock-speed deficit, although for some reason, its multi-threaded performance is trailing by over 15 percent.

Intel Rocket Lake CPUs Will Bring up to 10% IPC Improvement and 5 GHz Clocks

Intel is struggling with its node development and it looks like next-generation consumer systems are going to be stuck on 14 nm for a bit more. Preparing for that, Intel will finally break free from Skylake-based architectures and launch something new. The replacement for the current Comet Lake generation is set to be called Rocket Lake and today we have obtained some more information about it. Thanks to popular hardware leaker rogame (_rogame), we know a few stuff about Rocket Lake. Starting off, it is known that Rocket Lake features the backport of 10 nm Willow Cove core, called Cypress Cove. That Cypress Cove is supposed to bring only 10% IPC improvements, according to the latest rumors.

With 10% IPC improvement the company will at least offer some more competitive product than it currently does, however, that should be much slower than 10 nm Tiger Lake processors which feature the original Willow Cove design. It shows that backporting of the design doesn't just bring loses of the node benefits like smaller design and less heat, but rather means that only a fraction of the performance can be extracted. Another point that rogame made is that Rocket Lake will run up to 5 GHz in boost, and it will run hot, which is expected.

Intel has "Something Big to Share" on September 2nd

Intel just sent out press invites to what is likely an online media event slated for September 2, 2020. The spells nothing other than a one-liner "We have something big to share..." with the September 2 date. Everyone has a theory as to what this could be, depending on who you ask. The Verge has a valid theory pointing to this being a formal launch of the 11th Gen Core "Tiger Lake" mobile processors on the basis of several notebook manufacturers slating their "Tiger Lake" based notebook launches on "Fall 2020."

We believe this could be a desktop-related unveil, possibly a performance preview or teaser of the company's 11th Gen "Rocket Lake-S" processor. Why September? Because September 2020 is going to be a busy month for AMD and NVIDIA, with both launching their next-gen consumer graphics architectures, product lines; and more interestingly, AMD rumored to launch its "Zen 3" microarchitecture in some shape or form. A Ryzen 4000 "Vermeer" product launch could trigger Intel to at least preview "Rocket Lake-S," as it's the first client-desktop microarchitecture in 5 years to introduce IPC gains on the backs of new "Cypress Cove" CPU cores that are a 14 nm back-port of "Willow Cove." It wouldn't surprise us if Intel shed more light on the performance throughput of its big new Xe graphics processors.
