AMD Ryzen 7 5700G and Ryzen 5 5600G Already Outselling 5800X and 5600X on Mindfactory

German online retailer Mindfactory may not be as big as Amazon, but it puts out its sales figures of PC hardware components, that often get picked up by the tech-press as a sample size. While using its data as a yardstick for AMD outselling Intel in the DIY market is debatable, sales of individual AMD or Intel products provide valuable insights to what consumers are after these days. Apparently, the recently launched Ryzen 7 5700G and Ryzen 5 5600G APUs are already outselling the Ryzen 7 5800X and Ryzen 5 5600X, respectively, for the week of 2nd August running.

AMD designed the Ryzen 7 5700G to succeed the popular Ryzen 7 3700X, and the 5600G to succeed the best-selling Ryzen 5 3600, which explains the absence of "Ryzen 7 5700X" or "Ryzen 5 5600," at least in the DIY market. It's little surprise then, that just as the 3700X outsold the 3800X, Mindfactory bagged orders for 820 units of 5700G, as opposed to 610 units of the 5800X; and 900 units of the 5600G, compared to 680 units of the 5600X. It's interesting to note that the 5700G even outsold the 5600X. The 5700G and 5600G are based on the 7 nm "Cezanne" silicon, which packs up to 8 "Zen 3" cores, and an iGPU with up to 512 stream processors. Unlike "Vermeer," Cezanne is a monolithic die.

AMD "Zen 3" 3D Vertical Cache Detailed Some More

Senior Technology Fellow Yuzo Fukuzaki shed light on the elusive new CPU technology AMD unveiled at its Computex 2021 keynote, 3D Vertical Cache (3DV Cache). The company had then detailed it as an additional 64 MB last-level cache stacked on top of a CCD (CPU core complex die), which significantly improves performance, including a claimed 15% average gain in gaming performance, which accounts for a generational performance gain over "Zen 3." The prototype AMD unveiled in its keynote was based on a Socket AM4 processor with "Zen 3" CCDs that have the 3DV Cache components in place. With two such CCDs, a 16-core processor would end up with 192 MB of L3 cache.

Yuzo Fukuzaki's theory sheds light on the most plausible position of 3DV Cache in the processor's cache hierarchy. Apparently, it expands the CCD's L3 cache, and doesn't serve as an "L4" victim cache to the L3. This way, the cache setup remains transparent to the OS, which sees it as a contiguous 96 MB block of L3 cache (per CCD). The 3DV Cache die is an SRAM chip fabricated on the same 7 nm process as the "Zen 3" CCD. It measures 6 mm x 6 mm (36 mm²), and is located above the region of the CCD that typically has the 32 MB L3 SRAM. Fukuzaki estimates that roughly 23,000 TSVs (through-silicon vias), each about 17 µm in size, connect the 3DV Cache die to the main CCD.

AMD Zen 4 and RDNA3 Confirmed for 2022, Zen 3 Refresh

AMD CEO Dr Lisa Su, in the company's Q2-2021 financial results call, confirmed that the company is on-track to launch the Zen 4 CPU microarchitecture and RDNA3 graphics architecture, in 2022. Zen 4 would herald the first major desktop platform change since the original Zen architecture, with the introduction of a new CPU socket, and support for DDR5 memory. The RDNA3 graphics architecture, meanwhile, is expected to nearly triple SIMD resources over the previous generation, and introduce even more fixed-function hardware for raytracing.

In the meantime, AMD is preparing a counter to Intel's 12th Gen Core "Alder Lake-S" processor, in the form of Zen 3 with 3D Vertical Cache, which is also being referred to as the Zen 3+ architecture. These processors feature additional last-level cache, and the company claims a 15% gaming performance uplift, which should help it close the gaming performance gap with Intel, and win on sheer core-count of its big cores. It remains to be seen if Zen 3+ remains on Socket AM4 or if it debuts AM5, as AMD will be under pressure to match "Alder Lake" in platform I/O, which includes DDR5. Dr Su also confirmed that AMD has started shipping the Instinct MI200 "Aldebaran" compute accelerator based on the CDNA2 architecture. AMD's first MCM GPU with two logic dies, "Aldebaran" takes the fight to NVIDIA's top A100 series compute accelerators, and has already scored wins with ongoing HPC/supercomputing projects.

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).

AMD Ryzen Threadripper 5000 "Chagall" Processors Arrive This August in Both sTRX4 and sWRX8 Variants

AMD is preparing to launch the Ryzen Threadripper 5000 "Chagall" HEDT processors in August 2021, according to a MoePC report, confirming a rumor from April 2021. These chips will arrive in core-counts of up to 64, spanning two CPU socket types—sTRX4 (Ryzen Threadripper) and sWRX8 (Ryzen Threadripper PRO), and compatible with existing motherboards that run Ryzen 3000 Threadrippers, requiring a UEFI firmware update. Nearly every retail sTRX4 motherboard we've come across features USB BIOS Flashback, letting you update the firmware of an off-the-shelf motherboard without needing to install a compatible processor.

What's new with the Ryzen Threadripper 5000 is the new "Zen 3" CCDs, which place all 8 CPU cores of the die into a single CCX, sharing a unified 32 MB L3 cache. The I/O is identical to the previous generation, with the sTRX4 chips featuring quad-channel DDR4 interface, and sWRX8 ones featuring 8-channel, both with ECC; and up to 88 PCI-Express Gen 4 lanes. AMD also slightly increased the xGMI2 bandwidth to 18 GT/s, from 16 GT/s on the Ryzen Threadripper 3000 series.

Many Thanks to DeathtoGnomes for the tip.

AMD Ryzen Embedded V3000 SoCs Based on 6nm Node, Zen 3 Microarchitecture

AMD's next generation Ryzen Embedded V3000 system-on-chips aren't simply "Cezanne" dies sitting on BGA packages, but rather based on a brand new silicon, according to Patrick Schur, a reliable source with leaks. The die will be built on the more advanced 6 nm silicon fabrication node, whilst still being based on the current "Zen 3" microarchitecture. There are several things that set it apart from the APU silicon of the current-generation, making it more relevant for the applications the Ryzen Embedded processor family is originally built for.

Built in the FP7r2 BGA package, the V3000 silicon features an 8-core/16-thread CPU based on the "Zen 3" microarchitecture. There are also an integrated GPU based on the RDNA2 graphics architecture, with up to 12 CUs, a dual-channel DDR5 memory interface, a 20-lane PCI-Express 4.0 root complex, with up to 8 lanes put out for PEG; two USB4 ports, and two 10 GbE PHYs. AMD could design at least three SKUs based on this silicon, spanning TDP bands of 15-30 W and 35-54 W.

AMD Socket AM5 Motherboards Arriving in 2022, Paves Way for Zen3 + 3DV Cache on AM4

AMD Socket AM5 motherboards are set to arrive in Q2-2022, according to PJ, the editor of Uniko's Hardware. This would mean that the Zen 3 + 3D Vertical Cache chiplet AMD CEO Dr Lisa Su showed off in her Computex keynote, could very well be built in the Socket AM4 package, compatible with existing motherboards. The prototype Dr Su showed off appeared Socket AM4, too. AMD claims that the 3D Vertical Cache feature, when paired with a "Zen 3" chiplet, improves gaming performance by a significant 15 percent, helping AMD catch up with Intel's "Rocket Lake-S" processor at gaming. Elsewhere across the landscape, PJ predicts that the Z690 chipset, which goes with "Alder Lake-S" processors in the LGA1700 package, will arrive by Q4 2021, with cost-effective chipsets such as the B660 and H610 in Q1-2022.

AMD Shares New Details on Their 3D V-Cache Tech for Zen 3+

AMD via its official YouTube has shared a video that goes into slightly more detail on their usage of V-Cache on the upcoming Zen 3+ CPUs. Firstly demoed to the public on AMD's Computex 2021 event, the 3D V-Cache leverages TSMC's SoIC stacking technology, which enables silicon developments along the Z axis, instead of the more usual footprint increase along the X axis. The added 3D V-Cache, which was shown in Computex as being deployed in a prototype Ryzen 9 5900X 12-core CPU, adds 64 MB of L3 cache to each CCX (the up-to-eight-cores core complex on AMD's latest Zen design), basically tripling the amount of L3 cache available for the CPU. This, in turn, was shown to increase FPS in games quite substantially (somewhere around 15%), as games in particular are sensitive to this type of CPU resources.

The added information explains that there is no usage of microbumps - instead, there is a perfect alignment between the bottom layer (with the CCX) and the top layer (the L3 cache) which enables the bonding process to occur naturally via the TSVs (Through Silicon Vias) already present in the silicon, in a zero-gap manner, between both halves of the CPU-cache sandwich. To enable this, AMD flipped the CCX upside down (the core complex now faces the bottom of the chip, instead of the top), shaved 95% of the silicon on top of the upside-down core complexes, and then attaches the 3D V-Cache chips on top of this formation. This also has the added bonus of decreasing the distance between the L3 cache and the CCX (the distance between both in the Z axis is around 1,000 times smaller than if the L3 cache was deployed in the classical X axis), which decreases power consumption, temperatures, and latency, allowing for further increases to system performance. Look after the break for the full video.

AMD "Milan-X" Processor Could Use Stacked Dies with X3D Packaging Technology

AMD is in a constant process of processor development, and there are always new technologies on the horizon. Back in March of 2020, the company has revealed that it is working on new X3D packaging technology, that integrated both 2.5D and 3D approaches to packing semiconductor dies together as tightly as possible. Today, we are finally getting some more information about the X3D technology, as we have the first codename of the processor that is featuring this advanced packaging technology. According to David Schor, we have learned that AMD is working on a CPU that uses X3D tech with stacked dies, and it is called Milan-X.

The Milan-X CPU is AMD's upcoming product designed for data center usage. The rumors suggest that the CPU is designed for heavy bandwidth and presumably a lot of computing power. According to ExecutableFix, the CPU uses a Genesis-IO die to power the connectivity, which is an IO die from EPYC Zen 3 processors. While this solution is in the works, we don't know the exact launch date of the processor. However, we could hear more about it in AMD's virtual keynote at Computex 2021. For now, take this rumor with a grain of salt.

Intel to Detail "Alder Lake" and "Sapphire Rapids" Microarchitectures at Hot Chips 33, This August

Intel will detail its 12th Gen Core "Alder Lake" client and "Sapphire Rapids" server CPU microarchitectures at the Hot Chips 33 conclave, this August. In fact, Intel's presentation leads the CPU sessions on the opening day of August 23. "Alder Lake" will be the session opener, followed by AMD's presentation of the already-launched "Zen 3," and IBM's 5 GHz Z processor powering its next-gen mainframes. A talk on Xeon "Sapphire Rapids" follows this. Hot Chips is predominantly an engineering conclave, where highly technical sessions are presented by engineers from major semiconductor firms; and so the sessions on "Alder Lake" and "Sapphire Rapids" are expected to be very juicy.

"Alder Lake" is Intel's attempt at changing the PC ecosystem by introducing hybrid CPU cores, a concept introduced to the x86 machine architecture with "Lakefield." The processor will also support next-generation I/O, such as DDR5 memory. The "Sapphire Rapids" server CPU microarchitecture will see an increase in CPU core counts, next-gen I/O such as PCI-Express 5.0, CXL 1.1, DDR5 memory, and more.

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.

AMD Ryzen 7 5700G and Ryzen 5 5600G "Zen 3" Cezanne Desktop Processors Benched

Several benchmark numbers of the upcoming AMD Ryzen 7 5700G and Ryzen 5 5600G desktop processors were fished out by Thai PC enthusiast TUM_APISAK. The 5700G and 5600G are based on the 7 nm "Cezanne" silicon that combines up to 8 "Zen 3" CPU cores across a single CCX, sharing a single 16 MB L3 cache; along with an iGPU based on the "Vega" graphics architecture. Both chips were put through the CPU-Z Bench, where they posted spectacular results.

Both chips post higher single-thread score than the Core i9-10900K "Comet Lake," riding on the back of the high IPC of the "Zen 3" cores, and low latencies from the monolithic "Cezanne" silicon. In the multi-threaded test, the 8-core/16-thread 5700G scored above the Core i9-9900KS (5.00 GHz all-core). An HP OMEN 25L pre-built was put through Geekbench 5, where it was found performing within 90% of the Core i5-11600K. Userbenchmark remarks that the 5600X performs within the league of contemporaries, but falls behind on memory latency. Find the validation pages in the source links below.

AMD Breaks Through Cinebench R23 World Record With Dual Epyc Build

AMD via its official YouTube channel shared a video of two of its Epyc chips destroying Cinebench's R23 benchmark, setting a new world record in the process. The record-setting feat was achieved with two off-the shelf Epyc 7763 CPUs - the ones with 64 physical CPUs and 128 threads of Zen 3 IPC. The system, which was built on top of a reference server motherboard and paired with server-grade aircooling, reached a grand total of 113,631 points - completing the benchmark run is around ten (10) measly seconds and soaring through the previous record-holder, a heavily overclocked Ryzen Threadripper 3990X (105,170 points).

The AMD system crushes the closest-priced Intel Xeon CPUs in performance - a dual Intel Xeon Platinum 8380 (Ice Lake-SP generation) configuration reached a comparably paltry 74,630 points - and AMD wins in the price-performance ratio again, with each of its Epyc 7763 CPUs costing $7,890 compared to $8,100 for each of the Intel Xeon platinum 8380. AMD's name of choice for their server-grade CPUs offering up a justification for its admittedly 15-year-old naming scheme. Catch the AMD video after the break.

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 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.

ASUS ROG G15 with Radeon RX 6800M and Ryzen 9 5900HX Spotted

It's close to impossible finding a Ryzen 9 mobile processor-powered gaming notebook with a high-end NVIDIA GPU. Having returned to the high-end discrete GPU market with the "Big Navi" Radeon RX 6000 series, AMD is looking to complement its Ryzen 5000M series "Zen 3" Cezanne mobile processors with high-end RDNA2 GPUs of its own. An upcoming model of the ASUS ROG G15 (2021) leaked to the web in a CPU-Z validation database (model: G513QY). This notebook packs a Ryzen 9 5900HX "Cezanne" 8-core/16-thread processor based on the "Zen 3" microarchitecture; but more interestingly, the discrete GPU is Radeon RX 6800M.

The desktop Radeon RX 6800 (non-XT) and RX 6700 XT have shown that AMD has achieved performance/Watt parity/leadership over NVIDIA with high-end GPUs. VideoCardz reports that the RX 6800M is likely based on a maxed-out 7 nm "Navi 22" silicon, with 2,560 stream processors, and 12 GB of GDDR6 memory across a 192-bit wide memory bus. The RX 6800M could play in the same performance league as the GA104-based GeForce RTX 3080 Mobile, given that the desktop RX 6700 XT is leveling up to the desktop RTX 3070. Given the 256-bit memory bus width of the larger "Navi 21" silicon, it's quite possible that AMD comes up with even higher mobile SKUs, so AMD-powered gaming notebooks finally match/beat Intel+NVIDIA combinations.

AMD Reportedly Preparing To Launch Zen 3 Ryzen Threadripper 5000 in August

The AMD Zen 3 architecture provided significant performance improvements with the company releasing server, desktop, and mobile processors featuring the architecture. AMD is yet to update their Threadripper lineup with the new architecture however that looks set to change with the company reportedly preparing to announce the next generation "Chagall" Threadripper 5000 processors in August. The Threadripper family is in dire need of a refresh with the latest 3000 series processors being launched back in November 2019. The new processors should be compatible with existing TRX40 motherboards with a simple BIOS update.

AMD Announces 3rd Generation EPYC 7003 Enterprise Processors

AMD today announced its 3rd generation EPYC (7003 series) enterprise processors, codenamed "Milan." These processors combine up to 64 of the company's latest "Zen 3" CPU cores, with an updated I/O controller die, and promise significant performance uplifts and new security capabilities over the previous generation EPYC 7002 "Rome." The "Zen 3" CPU cores, AMD claims, introduce an IPC uplift of up to 19% over the previous generation, which when combined by generational increases in CPU clock speeds, bring about significant single-threaded performance increases. The processor also comes with large multi-threaded performance gains thanks to a redesigned CCD.

The new "Zen 3" CPU complex die (CCD) comes with a radical redesign in the arrangement of CPU cores, putting all eight CPU cores of the CCD in a single CCX, sharing a large 32 MB L3 cache. This the total amount of L3 cache addressable by a CPU core, and significantly reduces latencies for multi-threaded workloads. The "Milan" multi-chip module has up to eight such CCDs talking to a centralized server I/O controller die (sIOD) over the Infinity Fabric interconnect.
