TSMC Employs AMD EPYC CPUs for Mission-Critical Manufacturing

Taiwan Semiconductor Manufacturing Company, the maker of various kinds of silicon products, is the manufacturer of AMD's EPYC processors. However, have you ever questioned what CPUs are actually behind TSMC? The answer to that question is quite simple. Today, we have come to know that TSMC is using AMD EPYC processors to power their manufacturing infrastructure and tape out thousands of wafers per month. AMD has published TSMC's case study, which pointed out that the total cost of ownership has been the main challenge of the Taiwanese company. By using AMD EPYC 7702P and 7F72 CPUs, TSMC addresses the need for both reliable and high-performing server infrastructure to power the manufacturing efforts. For research and development purposes, TSMC chose the 7F72 with 24 cores and a high clock speed of 3.2 GHz, which is ideal for the company needs and purposes.

For more details about TSMC's choices and solutions, read the case study here.

New Spectre Vulnerability Version Beats All Mitigations, Performance to Badly Degrade After the Fix

Researches from the University of Virginia and University of California San Diego have published their latest case study. The two universities have worked hard to discover a new Spectre vulnerability variant that can pass all of the existing Spectre mitigations and exploit all of the existing processors coming from Intel and AMD. The vulnerability exploits all of the existing x86 processors, and as it is new, there are not implementations of hardware mitigation. The whitepaper called "I see dead μops" takes the implementation of exploiting micro-op caches that could lead to a potential data leak in the processor, which is leading to a Spectre-type exploit.

Modern x86 processors break down complex instructions into smaller RISC-like units called micro-ops, in the frontend, where it makes the design of the backend part much simpler. The micro-ops are stored in the micro-ops cache. The paper is describing micro-op cache-based timing channel exploits in three primary settings: "a) across code regions within the same thread, but operating at different privilege levels, (b) across different co-located threads running simultaneously on different SMT contexts (logical cores) within the same physical core, and (c) two transient execution attack variants that leverage the micro-op cache to leak transiently accessed secrets, bypassing several existing hardware and software-based mitigations, including Intel's recommended LFENCE."

AMD Earnings Call: GPU Production is Ramping and Mobile GPUs are Set to Arrive Later This Quarter

The current supply of graphics cards has been very tight all over the world. Starting with the launch of the latest Radeon RX 6000 series of GPUs based on RDNA 2 architecture, AMD has found itself in big trouble when it comes to supply of the silicon, compared to the demand that exists for these new GPUs. We have discussed that many times in the past and saw that it represents a problem spanning everyone involved in getting the silicon chips to the hands of consumers. On Tuesday, April 27th, AMD held its Q1 2021 earnings call and webcast, where the company executives talked about the company's future, underlying problems, and ways of addressing them.

Among many topics covered in the call, AMD's President and CEO, Dr. Lisa Su, has talked about the GPU supply. According to Dr. Su, the company is ramping the production of its Radeon graphics cards, adding that the mobile Radeon GPU lineup is lurking. Here is a full quote from the earnings call.

Alphacool Presents Eiswolf 2 GPU-AIO for NVIDIA Ampere and AMD RDNA 2 GPUs

Alphacool today presents the Eiswolf 2 AIO solution (Reference design with backplate) for AMD Radeon RX 6800/6800XT/6900 and NVIDIA RTX 3080/3090 graphics cards. As with all of our AIO models, we only use copper radiators, however, for the first time, the Alphacool 360 mm NexXxoS ST30 all-copper radiator will be used in one of our GPU "all-in-one" solutions. For the fans, we now install the new Alphacool Aurora Rise 120 mm fan. The fan impresses with a max. statistical pressure of 3.17 mm/H2O and offers a max. air flow of 119.8m3/h, at a speed range of 0-2500rpm which can be controlled via PWM.

The decision to use the larger radiator in conjunction with our new fans provides a significant increase in cooling performance. The AIO is completed with the Eisblock Aurora water cooler, which actively cools all relevant components such as graphics memory and voltage converters in addition to the GPU chip. All components used (radiator, fan, cooler, DC-LT 2 pump) including connectors and hoses are part of the Alphacool custom cooling range and are therefore available separately. This means that we're not just offering a simple AIO solution here, but a real custom water cooling system (pre-assembled & pre-filled). Only the pump housing for the DC-LT 2 pump is a custom design and not available separately. Today we present only the Reference designs. In the near future, more solutions for graphics cards in custom design from various manufacturers will be available.

AMD Zen 5 "Strix Point" Processors Rumored To Feature big.LITTLE Core Design

AMD launched the 7 nm Zen 3 microarchitecture which powers Ryzen 5000 processors in late 2020, we expect AMD to follow this up with a Zen 3+ on 6 nm later this year and a 5 nm Zen 4 in 2022. We are now beginning to receive the first rumors about the 3 nm Zen 5 architecture which is expected to launch in 2024 in Ryzen 8000 series products. The architecture is reportedly known as "Strix Point" and will be manufactured on TSMC's 3 nm node with a big.LITTLE core design similar to the upcoming Intel Alder Lake and the Apple M1. The Strix Point lineup will consist exclusively of APUs and could feature up to 8 high-performance and 4 low-performance cores which would be less than what Intel plans to offer with Alder Lake. AMD has allegedly already set graphics performance targets for the processors and that they will bring significant changes to the memory subsystem but with rumors for a product 3 years away from launch take them with a healthy dose of skepticism.

AMD 4700S Processor Could be Repurposed Xbox Series X/S APU

The AMD 4700S is a new processor being advertised by Chinese manufactures as a complete ITX compatible solution. The processor is soldered to a custom "Cardinal" motherboard produced by AMD which lacks memory slots and instead features 16 GB of GDDR6 memory located around the processor. These specifications seem to closely reflect those of the Xbox Series X APU. The 4700S is an 8-core 16-thread 7 nm Zen 2 CPU with 12 MB cache and a boost clock of 4.0 GHz which is actually higher than that of the Xbox Series X/S at 3.8 GHz and 3.6 GHz respectively. This higher boost clock is likely due to the exclusion of an integrated GPU which increases the power available for the processor.

The seller also provided benchmarks for the processor in various Cinebench configurations where it outperformed the Intel Core i7-9700 and performed just below the AMD Ryzen 7 4750G. The processor paired with an RX 550 GPU also outperformed the Intel Core i7-9750H paired with an RTX 2060 and 32 GB memory in Cinebench and x264/x265 video encoding. The seller has a picture of the Xbox Series X APU in their advertising material for the new processor lending weight to the theory that these are reused processors which failed qualification.

What AMD Didn't Tell Us: 21.4.1 Drivers Improve Non-Gaming Power Consumption By Up To 72%

AMD's recently released Radeon Software Adrenalin 21.4.1 WHQL drivers lower non-gaming power consumption, our testing finds. AMD did not mention these reductions in the changelog of its new driver release. We did a round of testing, comparing the previous 21.3.2 drivers, with 21.4.1, using Radeon RX 6000 series SKUs, namely the RX 6700 XT, RX 6800, RX 6800 XT, and RX 6900 XT. Our results show significant power-consumption improvements in certain non-gaming scenarios, such as system idle and media playback.

The Radeon RX 6700 XT shows no idle power draw reduction; but the RX 6800, RX 6800 XT, and RX 6900 XT posted big drops in idle power consumption, at 1440p, going down from 25 W to 5 W (down by about 72%). There are no changes with multi-monitor. Media playback power draw sees up to 30% lower power consumption for the RX 6800, RX 6800 XT, and RX 6900 XT. This is a huge improvement for builders of media PC systems, as not only power is affected, but heat and noise, too.

Russia Develops First Domestic B450 Motherboard

When governments need a hardware upgrade, they will usually take the route of exploring options with security in mind. However, if you happen to have some engineering talent to employ on a new project, why wouldn't you just build a custom motherboard for your own purposes. Today, GS Group Holding and Philax, have announced that they are starting the manufacturing of Russia's first motherboard based on a B450 chipset from AMD. Looking at the motherboard, which you can see below, you might find it very similar to those of ASRock. And that is because Philax has a licensing agreement with ASRock to use the design of the B450M Pro4 motherboard, with the addition of a TPM module which is often used by government agencies, to produce this board.

Producing around 40,000 pieces, these motherboards are expected to handle anything from 4000 series to 5000 series of AMD processors. As far as the specifications go, the board is coming in a standard Micro-ATX form factor. It is equipped with four DDR4 memory slots that can take a memory with up to 3200 MHz speed. There are two PCIe 3.0 x16 slots and one PCIe 2.0 x1 slot, which are of course limited by CPU choice. The motherboard enables four SATA III and two M.2 ports for storage expansion. When it comes to I/O, the board features HDMI, D-Sub, DVI-D, four USB 3.1 Gen1, two USB 2.0, one USB Type-C, and one USB 3.1 Gen2 Type-A port. GS Group Holding and Philax also have a partnership that goes beyond just motherboards. They also plan to produce about 50,000 custom monitors for government purposes as well.

AMD Radeon Pro W6900X With Navi 21 Appears in Apple Mac Pro

Recently, Apple has updated its macOS operating system to support the next generation of GPUs for Mac devices, coming from AMD. The upcoming RDNA 2 GPU lineup in Macs will bring all the enhancements AMD made to the architecture, and pack it inside Apple's signature designs. Today, we have received information that Apple could refresh its Mac Pro lineup with AMD's Radeon Pro GPU based on RDNA 2 architecture. On Geekbench 5, there was a test run that was conducted on Apple Mac Pro "7.1" revision, that features not only Intel Cascade Lake-X processor but AMD's unreleased Radeon Pro W6900X graphics card designed for professional users.

While we don't know much about the exact specifications, we know that it features a Navi 21 GPU SKU. Judging by the naming scheme, the Radeon Pro W6900X is representing an Apple-exclusive GPU variant designed only for Mac Pro devices. A Chiphell leak has given us a sneak peek at the alleged card look, which you can see below. When it comes to performance, the Geekbench result measures Metal API performance and the Radeon Pro W6900X has managed to score 171448 points, which is even higher than the Radeon RX 6900 XT GPU, which tops out at 164294 points. Of course, this is representing a professional SKU, so there could be some tuning present as well.

EKWB: Cooling Of the Highest Magnitude Comes to Threadripper CPUs

EK, the leading computer liquid cooling gear manufacturer, is launching a new water block, tailor-made for AMD Ryzen Threadripper processors. The Magnitude sTRX4 is the most complex Threadripper CPU water block on the market to date. Our latest addition to the EK Quantum product line has no intention of succeeding or replacing its Velocity sTR4 counterparts, as the Magnitude water block is a rather sophisticated alternative optimized specifically for Zen 2 based AMD Threadripper CPUs.

EK-Quantum Magnitude sTRX4
The block will be available in the same four finishes as regular Magnitude blocks: Copper + Acetal, Nickel + Acetal (D-RGB), Nickel + Plexi (D-RGB), and Full Nickel. However, to distinguish the two acetal models, Copper + Acetal versions will feature an exclusive red frame by default. The award-winning, signature design truly sets the Magnitude apart, with every piece being CNC-milled from a solid piece of material. The three-dimensional aluminum mounting frame perfectly blends in with the asymmetrical shape of the Threadripper CPU socket while making the screws a seamless part of the water block. Strong edges and chamfers root this futuristic design firmly into the EK Quantum line. Magnitude proudly bears its prestigious iF Design Award.

AMD Radeon RX 6900 XTX Engineering Sample Pictured

AMD is in constant progress with its Radeon graphics card lineup and the company is always working on new models that will better suit the market. Today, we have interesting discovery. On Weibo, a Chinese microblogging website, a user has posted pictures of what appears to be an engineering sample of AMD's Radeon RX 6900 XTX graphics card variant. Having an all-in-one (AIO) water-cooled design with a 120 mm radiator, the card resembles a power-hungry design as we have seen with Radeon R9 Fury X and RX Vega 64 Liquid Edition, which were both graphics cards equipped with AIO water cooling. This engineering sample is no different.

Under the waterblock, there is a Navi 21 XTXH GPU SKU hidden. As we found out, this is a new Navi 21 XTX SKU that just features better binning compared to Navi 21 XTX, and thus it offers better overclocking potential. It is already present in three new models from various AIBs, like the PowerColor RX 6900 XT Liquid Devil Ultimate, ASRock RX 6900 XT OC Formula, and Sapphire RX 6900 XT Toxic Extreme graphics cards. It seems like AMD has prepared itself to launch this specific SKU in a reference design form, however, so far only AIBs have used the Navi 21 XTXH SKU. It is not yet clear if the Radeon RX 6900 XTX is ever going to hit the retail market, or it shall remain as it is - just an engineering sample.

Sapphire Launches Radeon RX 6900 XT TOXIC Extreme Edition, Based on XTXH Silicon

SAPPHIRE Technology announces the incoming TOXIC AMD Radeon RX 6900 XT Extreme Edition Graphics Card with unparalleled performance and an enriched AIO cooling solution to expand the DIY Enthusiast SAPPHIRE TOXIC lineup. Built and engineered for the die-hard gaming fanatic, the TOXIC AMD Radeon RX 6900 XT Extreme Edition is the fundamental piece of hardware to hit the apex spot in gaming performance.

AMD X570S Motherboard Spotted Alongside Ryzen 7 5700G APU

AMD seems to be preparing a chipset refresh, and this time, it is coming straight from the top-end market. When the company launched its high-end X570 chipset, it brought the PCIe 4.0 support, which many praised due to its capability to handle much faster NVMe drives. However, it seems like the company is not satisfied with that and it needs to release an updated chipset version called X570S. According to a popular hardware leaker, TUM_APISAK, we have discovered that GIGABYTE is preparing X570S Aorus Pro AX motherboard that will use the refreshed chipset. GIGABYTE already listed several Eurasian Economic Commission (EEC) listings, so the new chipset is sure to hit the market, just at an unknown time.

The S denotes the word silent, meaning that these updated chipsets are capable of working with passive cooling and possibly having a lower TDP compared to 11 and 15 Watts of the X570 chipsets for consumer and enterprise motherboards, respectively. The test was conducted using AMD's newly announced Ryzen 7 5700G processor. The 5000-series of APUs are so far limited to OEMs, so one would guess that GIGABYTE itself made the leak by using a public entry of CPU-Z validation.

GPU World Record Set by Der8auer on PowerColor RX 6900 XT Liquid Devil Ultimate - 3.225 GHz

Overclocker extraordinnaire Roman "der8auer" Hartung has achieved a new world record for GPU clockspeed with the help of exotic cooling and PowerColor's RX 6900 XT Liquid Devil Ultimate. The PowerColor Red Devil Ultimate features the latest and greatest bin of any RX 6900 XT chip, featuring AMD's Navi 21 XTXH silicon (device ID 0x73AF), with improved clockspeed potential and lower leakage than the usual XT cadre of chips. Using LN2 cooling which dropped the operating temperatures of the card down to a finger-killing -87 °C, the overclocker managed to reach a 3,225 MHz clock - as reported by our very own GPU-Z, which continues to be the diagnostics tool of choice for graphics cards. Look after the break for the full video leading up to this overclocking feat.

AMD Enables FidelityFX Suite on Xbox Series X|S

AMD has announced that Microsoft's Xbox Series S|X now features support for the company's FidelityFX suite. This move, which enabled previously PC-centric technologies on Microsoft's latest-generation gaming consoles, will bring feature parity between RDNA 2-powered graphics, and will eventually enable support for AMD's FSR (FidelityFX Super Resolution), the company's eventual competition to NVIDIA's DLSS tech.

This means that besides the technologies that are part of the DX 12 Ultimate spec (and which the consoles already obviously support), developers now have access to AMD's Fidelity FX technologies such as Contrast Adaptive Sharpening, Variable Rate Shading, ray traced shadow Denoiser, Ambient Occlusion and Screen Space Reflections. All of these AMD-led developments in the SDK allow for higher performance and/or better visual fidelity. However, the icing on the cake should be the FSR support, which could bring the Series X's 8K claims to bear (alongside high-refresh-rate 4K gaming) - should FSR turn out be in a similar performance-enhancing ballpark as NVIDIA's DLSS, which we can't really know for sure at this stage (and likely neither can AMD). No word on Fidelity FX support on the PS5 has been announced at this time, which does raise the question of its eventual support, or if Sony will enable a similar feature via their own development tools.

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.

GPU Memory Latency Tested on AMD's RDNA 2 and NVIDIA's Ampere Architecture

Graphics cards have been developed over the years so that they feature multi-level cache hierarchies. These levels of cache have been engineered to fill in the gap between memory and compute, a growing problem that cripples the performance of GPUs in many applications. Different GPU vendors, like AMD and NVIDIA, have different sizes of register files, L1, and L2 caches, depending on the architecture. For example, the amount of L2 cache on NVIDIA's A100 GPU is 40 MB, which is seven times larger compared to the previous generation V100. That just shows how much new applications require bigger cache sizes, which is ever-increasing to satisfy the needs.

Today, we have an interesting report coming from Chips and Cheese. The website has decided to measure GPU memory latency of the latest generation of cards - AMD's RDNA 2 and NVIDIA's Ampere. By using simple pointer chasing tests in OpenCL, we get interesting results. RDNA 2 cache is fast and massive. Compared to Ampere, cache latency is much lower, while the VRAM latency is about the same. NVIDIA uses a two-level cache system consisting out of L1 and L2, which seems to be a rather slow solution. Data coming from Ampere's SM, which holds L1 cache, to the outside L2 is taking over 100 ns of latency.

CPU-Z Enables Preliminary Support for Intel Alder Lake CPUs

CPU-Z, the CPU monitoring tool used to gather information about the processor your system is running on, has been updated with version 1.96. This new update doesn't change the software much but rather brings support for new hardware. Starting from this revision, Intel's upcoming Alder Lake CPUs have received preliminary support in the tool. To go along with CPUs, the software is now also enabled to recognize Intel's Z6xx motherboards that pair with Alder Lake processors. Alongside that, the software now also brings support for next-generation DDR5 memory, which is supposed to feature speeds anywhere from 4800 to 8400 MT/s. When it comes to AMD, the tool received an update that enables it to read information about AMD's Ryzen 5700G, 5600G, and 5300G APUs, and Radeon RX 6900 XT, 6800 (& XT), 6700 XT GPUs.
