EVGA Goes Red, Teases The First Ever Motherboard Made for AMD Ryzen Processors

EVGA Corporation, or simply EVGA as it is known in the community, is the maker of various PC components and peripherals. As many of you are aware, EVGA has historically been focused on making products based on silicon coming from NVIDIA and Intel. The company has used NVIDIA products exclusively for its GPU portfolio and used Intel chipsets for its motherboard solutions. In the past, EVGA made motherboards for AMD processors, however, these boards used NVIDIA's chipset so they weren't technically full AMD motherboards. Starting today, that is about to change as we got some very juicy teasers from EVGA. In the nine-second video teaser on YouTube titled "A new Darkness is coming...", EVGA showcased a simple animation showing the AMD Ryzen logo surrounding EVGA's.

And of course, that only means one thing. EVGA will officially be joining the ecosystem of AMD and offering motherboards for their Ryzen processors. While the company is "one of the top NVIDIA authorized partners" in GPUs, on the CPU front it is officially joining Team Red and marking an important milestone for everyone. It is still not clear what kind of motherboard we will be getting, however, we can expect to see EVGA's best engineering applied in the form of a possible X570 Dark motherboard.

AMD Ryzen 7000 Series "Raphael" Zen 4 Processor IHS Design Gets Leaked

AMD is preparing to switch things up a bit with its upcoming AM5 platform. The new platform is said to bring significant changes to the design of the socket and the CPU package, where we will see some new design choices and decisions. For starters, all of the processors made for the AM5 platform will come in a land grid array (LGA) configuration, very similar to that of Intel. Thanks to the rendering of ExecutableFix, we got to see exactly how will the new LGA design look like. And today, we get to see more details of the AMD's upcoming Raphael processor's integrated heat spreader (IHS) design.

The IHS serves the purpose of spreading the heat away from the die and dissipating it efficiently. However, IHS designs can sometimes be very interesting. According to this rendering from ExecutableFix, AMD's upcoming Raphael design, based on Zen 4 core, will feature a unique IHS design, which can be seen below.

AMD Ryzen 8000 Series Processors Based on Zen 5 Architecture Reportedly Codenamed "Granite Ridge"

Today, we have talked about AMD's upcoming Raphael lineup of processors in the article you can find here. However, it seems like the number of leaks on AMD's plans just keeps getting greater. Thanks to the "itacg" on Weibo, we have learned that AMD's Ryzen 8000 desktop series of processors are reportedly codenamed as Granite Ridge. This new codename denotes the Zen 5 based processors, manufactured on TSMC's 3 nm (N3) node. Another piece of information is that AMD's Ryzen 8000 series APUs are allegedly called Strix Point, and they also use the 3 nm technology, along with a combination of Zen 5 and Zen 4 core design IPs. We are not sure how this exactly works out, so we have to wait to find out more.

AMD has recently confirmed that the upcoming B2 stepping for Ryzen 5000 processors will only improve production and availability with no impact on performance. The new stepping will be deployed within the next 6 months and will be fully compatible with existing motherboards without the need for a BIOS update. We initially believed that the new revisions may bring small performance improvements similar to existing Ryzen XT products however with this recent confirmation from AMD we now know that this is not the case. AMD has not confirmed if they are preparing a potential Ryzen 5000XT series which would likely be the final release on the AM4 platform.
AMDAs part of our continued effort to expand our manufacturing and logistics capabilities, AMD will gradually move AMD Ryzen 5000 Series Desktop Processors to B2 Revision over the next 6 months. The revision does not bring improvements in terms of functionality or performance, furthermore, no BIOS update will be required.

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.

Rumor: AMD Ryzen 7000 (Raphael) to Introduce Integrated GPU in Full Processor Lineup

The rumor mill keeps crushing away; in this case, regarding AMD's plans for their next-generation Zen designs. Various users have shared pieces of the same AMD roadmap, which apparently places AMD in an APU-focused landscape come their Ryzen 7000 series. we are currently on AMD's Ryzen 5000-series; Ryzen 6000 is supposed to materialize via a Zen 3+ design, with improved performance per watt obtained from improvements to its current Zen 3 family. However, Ryzen 7000-series is expected to debut on AMD's next-gen platform (let's call it AM5), which is also expected to introduce DDR5 support for AMD's mainstream computing platform. And now, the leaked, alleged roadmaps paint a Zen 4 + Navi 2 APU series in the works for AMD's Zen 4 debut with Raphael - roadmapped for manufacturing at the 5 nm process.

The inclusion of an iGPU chip with AMD's mainstream processors may signal a move by AMD to produce chiplets for all of its products, and then integrating them in the final product. You just have to think about it in the sense that AMD could "easily" pair one of the eight-core chiplets from the current Ryzen 5800X, for example, with an I/O die (which would likely still be fabricated with Global Foundries) an an additional Navi 2 GPU chiplet. It makes sense for AMD to start fabricating GPUs as chiplets as well - AMD's research on MCM (Multi-Chip Module) GPUs is pretty well-known at this point, and is a given for future development. It means that AMD needed only to develop one CPU chiplet and one GPU chiplet which they can then scale on-package by adding in more of the svelte pieces of silicon - something that Intel still doesn't do, and which results in the company's monolithic dies.

AMD Launches Ryzen 5000G "Cezanne" APU Lineup for OEMs

AMD has today decided to launch the next generation of Accelerated Processing Units (APUs), now in form of the 5000G lineup codenamed Cezanne. The APUs are getting launched as OEM-exclusive products for now, which means that only manufacturers like Dell, HP, Lenovo, etc. can have access to them. AMD is set to announce these processors for wider masses, such as consumer DIYers, later this year. So you must be wondering what is new about the 5000G APUs. For starters, the new APUs feature AMD's improved Zen 3 core with a notable IPC boost over Zen 2 found in last generation 4000G APUs. When it comes to graphics, the new APUs feature anywhere from 6-8 GPU cores, based on the Vega architecture.

When it comes to the available models, AMD lists six SKUs, all differentiating in CPU/GPU core count, TDP, and frequency. There are three regular SKUs, with their power-efficient variants. The regular SKUs are AMD Ryzen 7 5700G, Ryzen 5 5600G, and Ryzen 3 5300G. They are normal SKUs that have a TDP of 65 Watts, meaning a higher base frequency needing a more adequate cooling solution. However, as there are regular SKUs, there are also power-efficient, TDP-constrained models present. Called the AMD Ryzen 7 5700GE, Ryzen 5 5600GE, and Ryzen 3 5300GE, these models bring the TDP down to 35 Watts and reduce base frequency by a couple of hundreds of MHz.

AMD Launches Ryzen 9 5900 & Ryzen 7 5800 OEM Processors

Alienware Launches m15 R5 Ryzen Edition Laptop With up to AMD Ryzen 9 5900HX and NVIDIA GeForce RTX 3070

Dell's gaming subsidiary, Alienware, has launched a product designed to reintroduce products of a company that was abandoned in the laptop sector a long time ago. Alienware's last AMD-based gaming laptop made an appearance in 2007, and for 14 years there wasn't an Alienware laptop with an AMD processor inside it. For all those years, the heart of Alienware laptops was promised to Intel, however, that is no longer the case. Today, Alienware has introduced a Ryzen edition of the m15 R5 gaming laptop, powered by... you guessed it, AMD Ryzen 5000 series of mobile processors.

The new Alienware m15 R5 Ryzen Edition laptop is set to bring the balance to the force. Featuring AMD's flagship Ryzen 9 5900HX overclockable processor, the CPU is paired with NVIDIA's GeForce RTX 3070 graphics card.

AMD Ryzen 5000 Series CPUs with Zen 3 Cores Could be Vulnerable to Spectre-Like Exploit

AMD Ryzen 5000 series of processors feature the new Zen 3 core design, which uses many techniques to deliver the best possible performance. One of those techniques is called Predictive Store Forwarding (PSF). According to AMD, "PSF is a hardware-based micro-architectural optimization designed to improve the performance of code execution by predicting dependencies between loads and stores." That means that PSF is another "prediction" feature put in a microprocessor that could be exploited. Just like Spectre, the feature could be exploited and it could result in a vulnerability in the new processors. Speculative execution has been a part of much bigger problems in CPU microarchitecture design, showing that each design choice has its flaws.

AMD's CPU architects have discovered that the software that relies upon isolation aka "sandboxing", is highly at risk. PSF predictions can sometimes miss, and it is exactly these applications that are at risk. It is reported that a mispredicted dependency between load and store can lead to a vulnerability similar to Spectre v4. So what a solution to it would be? You could simply turn it off and be safe. Phoronix conducted a suite of tests on Linux and concluded that turning the feature off is taking between half a percent to one percent hit, which is very low. You can see more of that testing here, and read AMD's whitepaper describing PSF.
