Intel Core i5-12400 Could be the Next Price-Performance King, Beats Ryzen 5 5600X in Leaked Benchmarks

Intel's upcoming Core i5-12400 "Alder Lake-S" processor could be an interesting piece of silicon. Apparently, not all 12th Gen Core i5 desktop chips have the same core-configuration. While the top Core i5-12600K is expected to have six "Golden Cove" P cores and four "Gracemont" E-cores, some of the lower variants, such as the i5-12400, will lack E cores, and be pure P core chips. In this case, the chip is 6-core/12-thread with just P cores; 1.25 MB of dedicated L2 cache per core, and 18 MB of shared L3 cache. You'll probably get all the next-gen I/O, including PCI-Express Gen 5 (PEG slot), a PCI-Express Gen 4 CPU-attached NVMe slot, and DDR5+DDR4 memory.

Given that the Core i5-11400 is a $190 part, even with a 10-15% price hike, the i5-12400 is expected to be under $220. The only drawbacks here are expected to be locked BClk multiplier, and rather low clock speeds of 4.00 GHz. A user on Chinese social media posted alleged Cinebench R20 results of the i5-12400. It scores 659 points in the single-threaded test, and 4784 points in the multi-threaded test. Wccftech tabulated this against known performance numbers of popular chips, and found that the i5-12400 might end up slightly ahead of the Ryzen 5 5600X, a currently-$300 part. The table also puts out leaked i9-12900K numbers, which indicate why AMD is rushing with "Zen 3+" with 3D Vertical Cache, instead of next-gen "Zen 4."

Intel Core i7-12700 Geekbenched, Matches Ryzen 7 5800X

Intel's upcoming Core i7-12700 (non-K) processor matches AMD's Ryzen 7 5800X in the Geekbench 5 benchmark. The i7-12700 is a locked 65 W TDP processor with 8 "Golden Cove" P-cores, and 4 "Gracemont" E-cores. 4 fewer E-cores, lower clocks, and lack of features such as Thermal Velocity Boost, is what differentiates the 12th Gen Core i7 from 12th Gen Core i9.

The Core i7-12700 allegedly scored 1595 points single-thread, along with 10170 points in the multi-threaded test. This puts it within 5% of the Ryzen 7 5800X in the single-threaded test (averaged from the Geekbench database), and within 2% in the multi-threaded. One has to consider that the i7-12700 lacks an unlocked multiplier, but should Intel 600-series chipset motherboards come with the same power-limit unlocks as the 400-series and 500-series; more performance can be squeezed out.

Intel Golden Cove P-Core Offers 19% IPC Gain Over Cypress Cove (Rocket Lake)

The 8 "Golden Cove" performance cores (P-cores) present on 12th Gen "Alder Lake-S" desktop processors offer an IPC gain of 19% over the "Cypress Cove" cores powering current 11th Gen "Rocket Lake-S" processors, claims Intel. This would put them at roughly 35% higher IPC than the "Skylake" cores that powered Intel client desktop processors until as recently as 2020, with the 10th Gen "Comet Lake." This 19% number, however, is presented as a geomean of performance improvement at iso-frequency, across a wide selection of tests that include SPEC CPU 2017, SYSmark 25, Crossmark, PCMark 10, WebXPRT3, and Geekbench 5.4.1.

The high IPC of the P-cores, coupled with the high rumored frequencies for the enthusiast i9-12900K part running well into 5.30 GHz or beyond, begins to explain how 8 of these "Golden Cove" cores, coupled with 8 fairly fast "Gracemont" cores, closes in on the 16-core AMD Ryzen 9 5950X at Cinebench R20.

Intel's Secret Sauce at Catching Up with AMD Core Count is the Gracemont E-core and its Mind-boggling Perf/Watt

When early benchmarks of the Core i9-12900K "Alder Lake-S" processor showing performance comparable to AMD's top 16-core Ryzen 9 5950X surfaced, we knew something was up. 8 Intel P-cores and 8 E-cores, are able to match 16 "Zen 3" cores that are all performance cores. Apparently Intel is able to turn its P-core deficit around by taking a wacky approach. First, the 8 "Golden Cove" P-cores themselves offer significantly higher IPC than "Zen 3." Second, the 8 "Gracemont" E-cores aren't as "slow" as conventional wisdom would suggest.

Intel in its Architecture Day presentation put out some astounding numbers that help support how 8 big + 8 little cores are able to perform in the league of 16 AMD big cores. Apparently, on "Alder Lake-S," the 8 "Gracemont" E-cores enjoy a lavish power budget, and are able to strike an incredible performance/Watt sweet-spot. Intel claims that the "Gracemont" E-core offers 40% higher performance at ISO power than a "Skylake" core (Intel's workhorse P-core for desktops until as recently as 2020); which means it consumes 40% less power at comparable performance.

Intel Core i9-12900K Allegedly Beats AMD Ryzen 9 5950X at Cinebench R20

With qualification samples of the upcoming Intel Core i9-12900K "Alder Lake-S" processors and companion Socket LGA1700 motherboards hitting the black-market, expect a deluge of benchmarks on social media. One such that stands out makes a fascinating claim that the i9-12900K beats AMD's current flagship Ryzen 9 5950X processor at Cinebench R20, which has been AMD's favorite multi-threaded benchmark. At stock speeds, with liquid cooling, the i9-12900K allegedly scores 810 points in the single-threaded test, and 11600 points in multi-threaded.

To put these numbers into perspective, a retail Ryzen 9 5950X scores 641 points in the single-threaded test, and 10234 points in multi-threaded, in our own testing. The i9-12900K is technically a 16-core processor, just like the 5950X, but half its cores are low-power "Gracemont." The "Alder Lake-S" chip appears to be making up ground on the single-threaded performance of the "Golden Cove" P-core, that's a whopping 25% higher than the "Zen 3" core on the 5950X. This is aided not just by higher IPC, but also the max boost frequency of 5.30 GHz for 1~2 cores, and 5.00 GHz "all-core" boost (for the P-cores).

Intel Core i9-12900K Qualification Samples Black-marketed for Roughly $1100

Qualification samples (QS) of Intel's upcoming Core i9-12900K "Alder Lake-S" desktop processors just hit the black market for the equivalent of roughly USD $1,064 to $1,157 (6,500 to 7,500 RMB), in China. The processor maxes out the 10 nm silicon, offering 8 "Golden Cove" P-cores, and 8 "Gracemont" E-cores, along with 30 MB of L3 cache, a dual-channel DDR5 memory interface, in a hybrid processor setup. You can bag yourself this QS, but you'll need to find a compatible motherboard. "Alder Lake-S" debuts the new LGA1700 socket, Intel's first major change in the physical dimensions of its mainstream-desktop CPU socket since 2009, mandating a cooler update.

Specs of Top Intel 12th Gen Core "Alder Lake-S" Processors Surface

Intel will debut its 12th Gen Core "Alder Lake-S" desktop processors either toward the end of 2021, or early 2022, introducing the LGA1700 socket, 600-series chipset, and more importantly, hybrid CPU core architecture to the desktop space. The 10 nm "Alder Lake-S" silicon features up to eight "Golden Cove" performance cores (P-cores), and up to eight "Gracemont" efficiency cores (E-cores), in a heterogenous CPU core setup rivaling Arm big.LITTLE. Specifications of the top Core i9, fairly-top Core i7, and mid-tier Core i5 parts were leaked to the web on Chinese social media.

The 12th Gen Core lineup will be led, predictably, by the Core i9-12900K, which succeeds the i9-11900K with a maxed out 8+8 (P+E) configuration, unlocked multipliers, the most cache, and the highest clock speeds. The P-cores ("Golden Cove" cores) are clocked up to 5.30 GHz (1-2 cores boost), and up to 5.00 GHz all-core / 8 cores; while the E-cores ("Gracemont" cores), are clocked up to 3.90 GHz (1-4 cores boost), with 3.70 GHz all-core / 8 cores boost. The total L3 cache on the silicon is 30 MB. The i9-12900K has a TDP of 125 W (PL1), with 228 W PL2. Intel will introduce several new overclocking features, including multiple memory gear ratios.

Intel "Alder Lake" Mobile Processor SKU Stack Leaked

Armed with up to 8 "Golden Cove" high-performance CPU cores and up to 8 "Gracemont" low-power cores in a hybrid x86 processor setup, the "Alder Lake" silicon enables Intel to carve out some interesting SKUs in the mobile space, by creating numerous combinations of the big and small CPU core counts, and more importantly, by adjusting the ratio of big cores to small ones. The two core types operate at significantly different performance/Watt bands, which allows Intel to target the various TDP-defined mobile processor SKU categories with just the right big:small core ratios, as revealed by a leaked "Alder Lake" mobile SKU roadmap, leaked to the web by HXL.

Intel is looking to spread the silicon across six mobile segments defined by TDP—the 5 W tablet/handheld; the 9 W ultra-thin, the 15 W mainstream tablet/laptop, the 28 W performance tablet/laptop, the 35-45 W thin enthusiast laptop, and the 45-55 W "muscle" laptop. With Intel recently announcing the discontinuation of its 1+4 (big+small) core "Lakefield" hybrid processor, its mantle in the 5 W segment will be picked up by "Alder Lake-M5," with 1 "Golden Cove" and 4 "Gracemont" cores. There will be two product tiers segmented by iGPU execution units (EUs), one with 48 EU, and the other with 64.

Intel "Raptor Lake" is a 24-core (8 Big + 16 Little) Processor

Intel's strategy toward increasing CPU core counts could be to dial up the counts of smaller low-power CPU cores, according to a "Moore's Law is Dead" leak about the next-generation "Raptor Lake" mainstream processor. The chip is said to have 8 larger high-performance cores, and a whopping 16 low-power cores. The eight bigger performance cores will be "Raptor Cove," the successor to "Golden Cove," featuring higher IPC and more instruction sets, although the report only references this as an enhancement to "Golden Cove." The sixteen smaller low-power cores, however, are expected to remain "Gracemont," carried over from "Alder Lake-S." The "Raptor Lake-S" processor is slated for a Holiday 2022 release, and being touted as a competitor to AMD's "Zen 4" based desktop processor.

Intel 12th Gen Core Alder Lake to Launch Alongside Next-Gen Windows This Halloween

Intel is likely targeting a Halloween (October 2021) launch for its 12th Generation Core "Alder Lake-S" desktop processors, along the sidelines of the next-generation Windows PC operating system, which is being referred to in the press as "Windows 11," according to "Moore's Law is Dead," a reliable source of tech leaks. This launch timing is key, as the next-gen operating system is said to feature significant changes to its scheduler, to make the most of hybrid processors (processors with two kinds of CPU cores).

The two CPU core types on "Alder Lake-S," the performance "Golden Cove," and the low-power "Gracemont" ones, operate in two entirely different performance/Watt bands, and come with different ISA feature-sets. The OS needs to be aware of these, so it knows exactly when to wake up performance cores, or what kind of processing traffic to send to which kind of core. Microsoft is expected to unveil this new-gen Windows OS on June 24, with RTX (retail) availability expected in Q4-2021.

Intel "Alder Lake-P" Mobile Processor PL Values Revealed

Intel is preparing its 12th Gen Core "Alder Lake" processors to target not just desktop, but also notebook. The "Alder Lake-P" mobile processor will be Intel's second to implement a hybrid CPU core design (after "Lakefield"). Coelacanth Dream revealed the power level (PL) values of the three key variants of the "Alder Lake-P" silicon. Intel will create broadly three categories of mobile chips targeting specific notebook form-factors—15 W, 28 W, and 45 W. The "Alder Lake-U" 15 W chips are expected to have a PL1 value (interchangeable with the TDP marked on the tin), of 15 W, but its PL2 value, which enables the highest Turbo frequency, can be as high as 55 W.

The next category, the "Alder Lake-U" 28 W chips, have a PL2 value of 64 W. Lastly, the "Alder Lake-H" 45 W chip, which will go into notebooks of conventional thickness, is expected to have a PL2 value of a scorching 115 W. Unless we're mistaken, "Alder Lake-P" is a hybrid processor with up to 6 "Golden Cove" performance CPU cores, and up to 8 "Gracemont" low-power cores. The performance cores feature HyperThreading, and are AVX-512 capable. Unlike the desktop "Alder Lake-S," Intel is investing in a larger iGPU. Based on the Gen12 Xe LP graphics architecture, the iGPU of the "Alder Lake-P" could feature 96 execution units, compared to just 48 on the "Alder Lake-S."

Intel 12th Generation Alder Lake Platform Reportedly Brings 20% Single-Threaded Performance Uplift

Intel only just announced their 11th generation Rocket Lake-S desktop processors last week but we are already receiving information about the next generation Alder Lake-S platform which will finally make the jump to 10 nm. Intel slides for the upcoming family of processors have been leaked and they reveal some interesting information including a claimed 20% single-threaded performance increases from the new Golden Cove core design and 10 nm SuperFin node. The processors will feature Intel Hybrid Technology with a mix of small low-performance cores and large high-performance cores with a maximum of eight each for sixteen total cores. The processors will also include the latest connectivity with both PCIe 4.0 and PCIe 5.0 support along with DDR4 and DDR5 4800 MHz compatibility.

Intel will also be launching a new socket type called LGA1700 with a new package size which will render existing cooling solutions for LGA115X and LGA1200 sockets incompatible. The processors will also come with the launch of a new 600 Series chipset with PCIe 3.0 and PCIe 4.0 support along with the usual complement of USB, SATA, and networking. The entry-level 600-series motherboards will only support DDR4 memory at up to 3200 MHz while high-end Z690 motherboards will include DDR5 support. Intel has confirmed that they intend to launch Alder Lake later this year but it is yet to be known if they are referring to the desktop or mobile series.

Intel Prepares 19 Alder Lake Processors for Laptops Ranging from 5-55 Watts

As we are getting closer to the launch of Intel's next-generation Alder Lake processors, more information is getting leaked. Today, thanks to the leaked presentation slide, we have some more details regarding Intel's Alder Lake offerings in the laptop sector. As a reminder, Alder Lake uses a hybrid approach to core configuration with the similar mindset Arm's big.LITTLE works. There are a few smaller cores for processing smaller tasks that don't need much power and, of course, there are a few big cores that are used for heavyweight processing as some advanced applications require. The small cores are going to be based on the Gracemont microarchitecture, while the big one will use the Golden Cove design.

Thanks to @9550pro on Twitter, we have a slide that showcases 19 different Alder Lake configurations for the laptop segment. At the very bottom, there are configurations with a TDP of just five Watts. That is achieved by having just one big, four smaller cores, 48 EU Gen 12 GPU and that is meant for the tablet segment. Going up, we have different ranges depending on the application device, and the highest end is a chip with 55 Watts of power. That model has eight small and eight big cores, combined with 32 EUs of Gen 12 graphics. All models include integrated graphics. The variations of big and small cores have allowed Intel to have as many as 19 different SKUs, that cover every segment needed, by simply balancing the core count. You can check out the rest of the models below for yourself.

Intel "Lunar Lake" Microarchitecture Hits the Radar, Possible "Meteor Lake" Successor

Intel published Linux kernel driver patches that reference a new CPU microarchitecture, codenamed "Lunar Lake." The patch comments refer to "Lunar Lake" as a client platform, and VideoCardz predicts that it could succeed "Meteor Lake." the microarchitecture that follows "Alder Lake," which was recently announced by Intel.

Targeting both mobile and desktop platforms, "Alder Lake" will herald a new 1,700-pin LGA socket for the client desktop, and debut hybrid CPU cores on the form-factor. Expected to be built on a newer silicon fabrication node, such as the 10 nm SuperFin, the chip will combine high-performance "Golden Cove" big cores, with "Gracemont" low-power cores. Its commercial success will determine if Intel continues to take the hybrid-core approach to client processors with future "Meteor Lake" and "Lunar Lake," or whether it will have sorted out its foundry woes and build "Lunar Lake" with a homogeneous CPU core type. With "Alder Lake" expected to debut toward the end of 2021 and "Meteor Lake" [hopefully] by 2022, "Lunar Lake" would only follow by 2023-24.

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 "Alder Lake-P" Mobile Processor with 14 Cores (6 Big + 8 Little) Geekbenched

An Intel 12th Gen Core "Alder Lake-P" sample surfaced on the Geekbench online results database. The "Alder Lake" microarchitecture introduces heterogenous multi-core to the desktop platform, following its long march from Arm big.LITTLE in 2013, through to laptops with Intel's "Lakefield" in 2019. Intel will build both desktop- and mobile processors using the microarchitecture. The concept is unchanged from big.LITTLE. A processor has two kinds of cores—performance and low-power. Under lower processing loads, the low-power cores are engaged, and the performance cores are only woken up as needed. In theory, this brings about tremendous energy-efficiency gains, as the low-power cores operate within a much higher performance/Watt band than the high-performance cores.

The "Alder Lake" silicon features two kinds of cores—eight "Golden Cove" performance cores, and eight "Gracemont" low-power cores. The "Golden Cove" cores can be configured with HyperThreading (2 logical processors per core). Intel's product managers can create multiple combinations of performance and low-power cores, to achieve total core counts of up to 16, and logical processor counts of up to 24. This also warrants close attention to the composition of the core types, beyond an abstract core-count. A 14-core processor with 6 performance- and 8 low-power cores will perform vastly different from a 14-core processor with 8 performance- and 6 low-power cores. One way to derive core counts is by paying attention to the logical processor (thread) counts, as only the performance "Golden Cove" cores support HTT.

16-Core Intel Alder Lake-S Processor Appears with DDR5 Memory

Intel has just launched its Rocket Lake-S desktop lineup of processors during this year's CES 2021 virtual event. However, the company is under constant pressure from the competition and it seems like it will not stop with that launch for this year. Today, thanks to the popular leaker @momomo_us on Twitter, we have the first SiSoftware entries made from the anonymous Alder Lake-S system. Dubbed a heterogeneous architecture, Alder Lake is supposed to be Intel's first desktop attempt at making big.LITTLE style of processors for general consumers. It is supposed to feature Intel 10 nm Golden Cove CPU "big" cores & Gracemont "small" CPU cores.

The SiSoftware database entry showcases a prototype system that has 16 cores and 32 threads running at the base frequency of 1.8 GHz and a boost speed of 4 GHz. There is 12.5 MB of L2 cache (split into 10 pairs of 1.25 MB) and 30 MB of level-three (L3) cache present on the processor. There is also an Alder Lake-S mobile graphics controller that runs at 1.5 GHz. Intel Xe gen 12.2 graphics is responsible for the video output. When it comes to memory, Alder Lake-S is finally bringing the newest DDR5 standard with a new motherboard chipset and socket called LGA 1700.

Intel 500 Series Motherboards to Supposedly Arrive on January 11th

Intel needs a platform refresh to battle the competition, mainly speaking to battle AMD and its Ryzen 5000 series processors. That is why the company is developing 500 series of chipsets covering the low-end (H510), mid-range (B560), and high-end markets (Z590) that pair with the upcoming Rocket Lake-S processor generation. Dubbed 11th generation of Core processors, the 11th generation of Intel Core CPUs are going to be built on Intel's refined 14 nm process. The CPUs are supposed to feature a Cypress Cove core, which is a backport of Golden Cove found in Ice Lake. The 500 series motherboards are the last in the DDR4 generation, launching in the timeframe when DDR5 is supposed to take over in the coming years.

Today, thanks to Weixin, a Chinese media outlet that posted a short story on the WeChat platform, we have information about the launch date of these new chipsets. According to the source, we are allegedly going to see these new chipsets on January 11th, the day that Intel CES 2021 event is supposed to happen. The platform will include a range of motherboards from Intel's partners and is supposed to bring support for the much-needed PCIe 4.0 protocol. The launch date should be taken with a grain of salt, of course, before taking it as a fact.

Intel Rocket Lake-S CPU Benchmarked: Up to 22% Faster Compared to the Previous Generation

Just a few days ago, Intel has decided to surprise us and give out information about its upcoming Rocket Lake-S platform designed for desktop users. Arriving early next year (Q1) the Rocket Lake-S platform is yet another iteration of the company's 14 nm node. However, this time we are getting some real system changes with a new architecture design. Backporting its Golden Cove core to 14 nm, Intel has named this new core type Cypress Cove. What used to be the heart of Ice Lake CPUs, is now powering the Rocket Lake-S platform. Besides the new core, there are other features of the platform like PCIe 4.0, new Xe graphics, and updated media codecs. You can check that out here.

Today, we have gotten the first benchmarks of the Intel Rocket Lake-S system. In the Userbenchmark bench, an unknown eight-core Rocket Lake CPU has been compared to Intel's 10th generation Comet Lake-S processors. The Rocket Lake engineering sample ran at 4.2 GHz while scoring a single-core score of 179. Compared to the Core i9-10900K that runs at 5.3 GHz, which scored 152 points, the Cypress Cove design is 18% faster. And if the new design is compared to the equivalent 8C/16T Compet Lake CPU like Core i7-10700K clocked at 5.1 GHz and scoring 148 points, the new CPU uarch is up to 22% faster. This represents massive single-threaded performance increases, however, please take the information with a grain of salt, as we wait for the official reviews.

Intel Alder Lake-S CPU Has Been Pictured

Intel has been preparing the launch of its 10 nm processors for desktop users for some time now, and today we are getting the first pictures of the Alder Lake-S CPU backside. Featuring a package with a size of 37.5×45 mm, the Alder Lake CPU uses more of its area for a pin count increase. Going up from 1200 pins in the LGA1200 socket, the new Alder Lake-S CPU uses 1700 CPU pins, which slots in the LGA1700 socket. In the picture below, there is an engineering sample of the Alder Lake-S CPU, which we see for the first time. While there is no much information about the processor, we know that it will use Intel's 10 nm SuperFin design, paired with hybrid core technology. That means that there will be big (Golden Cove) and little (Gracemont) cores in the design. Other features such as PCIe 5.0 and DDR5 should be present as well. The new CPU generation and LGA1700 motherboards are scheduled to arrive in second half of 2021.

Intel Alder Lake-S Processor with 16c/32t (Hybrid) Spotted on SANDRA Database

Intel's upcoming Core "Alder Lake-S" desktop processor, which is shaping up to be the first Hybrid desktop processor, surfaced on the SiSoft SANDRA benchmark database, as dug up by TUM_APISAK. The chip is reported by SANDRA to be 16-core/32-thread, although this is expected to be a combination of eight "big" high-performance cores, and eight "small" high-efficiency cores, in a multi-core topology similar to Arm big.LITTLE. Other specs read by SANDRA include clock speeds around "1.40 GHz," ten 1.25 MB L2 caches (possibly 8x 1.25 MB for the big "Golden Cove" cores, 2x 1.25 MB for the two groups of small "Gracemont" cores), and 30 MB of L3 cache. The Hybrid processor architecture is expected to introduce several platform-level innovations to the modern desktop, taking advantage of the extremely low power draw of the "Gracemont" cores when the machine isn't grinding serious workloads.

Coreboot Code Hints at Intel "Alder Lake" Core Configurations

Intel's 12th Gen Core EVO "Alder Lake" processors in the LGA1700 package could introduce the company's hybrid core technology to the desktop platform. Coreboot code leaked to the web by Coelacanth's Dream sheds fascinating insights to the way Intel is segmenting these chips. The 10 nm chip will see Intel combine high-performance "Golden Cove" CPU cores with energy-efficient "Gracemont" CPU cores, and up to three tiers of the company's Gen12 Xe integrated graphics. The "Alder Lake" desktop processor has up to eight big cores, up to eight small ones, and up to three tiers of the iGPU (GT0 being disabled iGPU, GT1 being the lower tier, and GT2 being the higher tier).

Segmentation between the various brand extensions appears to be primarily determined by the number of big cores. The topmost SKU has all 8 big and 8 small cores enabled, along with GT1 (lower) tier of the iGPU (possibly to free up power headroom for those many cores). The slightly lower SKU has 8 big cores, 6 small cores, and GT1 graphics. Next up, is 8 big cores, 4 small cores, and GT1 graphics. Then 8+2+GT1, and lastly, 8+0+GT1. The next brand extension is based around 6 big cores, being led by 6+8+GT2, and progressively lower number of small cores and their various iGPU tiers. The lower brand extension is based around 4 big cores with similar segmentation of small cores, and the entry-level parts have 2 big cores, and up to 8 small cores.

Intel 8-core "Tiger Lake-H" Coming in 2021: Leaked Compal Document

Intel is preparing to launch an 8-core mobile processor based on its 10 nm "Tiger Lake" microarchitecture, according to a corporate memo by leading notebook OEM Compal, which serves major notebook brands such as Acer. The memo was drafted in May, but unearthed by momomo_us. Compal expects Intel to launch the 8-core "Tiger Lake-H" processor in Q1 2021. This is big, as it would be the first large 10 nm client-segment silicon that goes beyond 4 cores. The company's first 10 nm client silicon, "Ice Lake," as well as the "Tiger Lake-U" silicon that's right around the corner, feature up to 4 cores. As an H-segment part, the new 8-core processor could target TDPs in the range of 35-45 W, and notebooks in the "conventional thickness" form-factor, as well as premium gaming notebooks and mobile workstations.

The 8-core "Tiger Lake-H" silicon is the first real sign of Intel's 10 nm yields improving. Up until now, Intel confined 10 nm to the U- and Y-segments (15 W and below), addressing only ultra-portable form-factors. Even here, Intel launched U-segment 14 nm "Comet Lake" parts at competitive prices, to take the market demand off "Ice Lake-U." The H-segment has been exclusively held by "Comet Lake-H." Intel is planning to launch "Ice Lake-SP" Xeon processors later this year, but like all server parts, these are high-margin + low-volume parts. Compal says Intel will refresh the H-segment with a newer 8-core "Comet Lake-H" part in the second half of 2020, possibly to bolster the high-end against the likes of AMD's Ryzen 9 4900H. Later in 2021, Intel is expected to introduce its 10 nm "Alder Lake" processor, including a mobile variant. These processors will feature Hybrid technology, combining "Golden Cove" big CPU cores with "Gracemont" small ones.

Intel Ice Lake-SP Processors Get Benchmarked Against AMD EPYC Rome

Intel is preparing to launch its next-generation for server processors and the next in line is the Ice Lake-SP 10 nm CPU. Featuring a Golden Cove CPU and up to 28 cores, the CPU is set to bring big improvements over the past generation of server products called Cascade Lake. Today, thanks to the sharp eye of TUM_APISAK, we have a new benchmark of the Ice Lake-SP platform, which is compared to AMD's EPYC Rome offerings. In the latest GeekBench 4 score, appeared an engineering sample of unknown Ice Lake-SP model with 28 cores, 56 threads, a base frequency of 1.5 GHz, and a boost of 3.19 GHz.

This model was put in a dual-socket configuration that ends up at a total of 56 core and 112 threads, against a single 64 core AMD EPYC 7442 Rome CPU. The dual-socket Intel configuration scored 3424 points in the single-threaded test, where AMD configuration scored notably higher 4398 points. The lower score on Intel's part is possibly due to lower clocks, which should improve in the final product, as this is only an engineering sample. When it comes to the multi-threaded test, Intel configuration scored 38079 points, where the AMD EPYC system did worse and scored 35492 points. The reason for this higher result is unknown, however, it shows that Ice Lake-SP has some potential.

Intel Linux Patch Confirms "Alder Lake" is a Hybrid Core Processor

A Linux kernel patch contributed and signed off by Intel confirms that its upcoming Core "Alder Lake" processor will feature a hybrid core topology, much like Core Hybrid "Lakefield." The patch references "Lakefield" and "Alder Lake" under "Hybrid Core/Atom Processors." The patch possibly gives the Linux kernel awareness of the hybrid core topology, so it can schedule its work between the two types of cores on the silicon accordingly, and avoid rotating between the two core groups. Under the Android project, Linux has been aware of a similar tech from Arm since 2013.

Analogous with Arm big.LITTLE, the Intel Hybrid Core technology involves two kinds of CPU cores on a processor die, the first kind being "high performance," and the second being "low power." On "Lakefield," Intel deployed one "Sunny Cove" high performance core, and four "Tremont" low power cores. The low power cores keep the machine ticking through the vast majority of time when processing workloads requiring the high performance cores aren't present. With "Alder Lake," Intel is expected to scale up this concept, with the silicon rumored to feature eight "Golden Cove" high performance cores, and eight "Gracemont" low power ones. The chip is also expected to feature a Gen12 Xe iGPU.
