AMD "Navi" Features 8 Streaming Engines, Possible ROP Count Doubling?

AMD's 7 nm "Navi 10" silicon may finally address two architectural shortcomings of its performance-segment GPUs, memory bandwidth, and render-backends (deficiency thereof). The GPU almost certainly features a 256-bit GDDR6 memory interface, bringing about a 50-75 percent increase in memory bandwidth over "Polaris 30." According to a sketch of the GPU's SIMD schematic put out by KOMACHI Ensaka, Navi's main number crunching machinery is spread across eight shader engines, each with five compute units (CUs).

Five CUs spread across eight shader engines, assuming each CU continues to pack 64 stream processors, works out to 2,560 stream processors on the silicon. This arrangement is in stark contrast to the "Hawaii" silicon from 2013, which crammed 10 CUs per shader engine across four shader engines to achieve the same 2,560 SP count on the Radeon R9 290. The "Fiji" silicon that followed "Hawaii" stuck to the 4-shader engine arrangement. Interestingly, both these chips featured four render-backends per shader engine, working out to 64 ROPs. AMD's decision to go with 8 shader engines raises hopes for the company doubling ROP counts over "Polaris," to 64, by packing two render backends per shader engine. AMD unveils Navi in its May 27 Computex keynote, followed by a possible early-July launch.

AMD Takes a Bigger Revenue Hit than Microsoft from Huawei Ban: Goldman Sachs

The trade ban imposed on Chinese tech giant Huawei by the U.S. Department of Commerce, and ratified through an Executive Order by President Donald Trump, is cutting both ways. Not only are U.S. entities banned from importing products and services from Huawei, but also engaging in trade with them (i.e. selling to them). U.S. tech firms stare at a $11 billion revenue loss by early estimates. Wall Street firm Goldman Sachs compiled a list of companies impacted by the ban, and the extent of their revenue loss. It turns out that AMD isn't a small player, and in fact, stands to lose more revenue in absolute terms than even Microsoft. It earns RMB 268 million (USD $38.79 million) from Huawei, compared to Microsoft's RMB 198 million ($28.66 million). Intel's revenue loss is a little over double that of AMD at RMB 589 million ($84 million), despite its market-share dominance.

That's not all, AMD's exposure is higher than that of Intel, since sales to Huawei make up a greater percentage of AMD's revenues than it does Intel's. AMD exports not just client-segment products such as Ryzen processors and Radeon graphics, but possibly also EPYC enterprise processors for Huawei's server and SMB product businesses. NVIDIA is affected to a far lesser extent than Intel, AMD, and Microsoft. Qualcomm-Broadcom take the biggest hit in absolute revenue terms at RMB 3.5 billion ($508 million), even if their exposure isn't the highest. The duo export SoCs and cellular modems to Huawei, both as bare-metal and licenses. Storage hardware makers aren't far behind, with the likes of Micron, Seagate, and Western Digital taking big hits. Micron exports DRAM and SSDs, while Seagate and WDC export hard drives.

Sapphire Reps Leak Juicy Details on AMD Radeon Navi

A Sapphire product manager and PR director, speaking to the Chinese press spilled the beans on AMD's upcoming Radeon Navi graphics card lineup. It looks like with Navi, AMD is targeting the meat of the serious gamer market, at two specific price points, USD $399 with a "Pro" (cut-down) product, and $499 with an "XT" (fully-fledged) product. AMD has two NVIDIA products in its crosshairs, the GeForce RTX 2070, and the RTX 2060. In the interview, the Sapphire rep mentioned "stronger than 2070", when talking about performance numbers, which we assume is for the Navi XT variant - definitely promising. The $399 Navi "Pro" is probably being designed with a performance target somewhere between the RTX 2060 and RTX 2070, so you typically pay $50 more than you would for an RTX 2060, for noticeably higher performance.

Sapphire also confirmed that AMD's Navi does not have specialized ray-tracing hardware on the silicon, but such technology will debut with "next year's new architecture". They also suggested that AMD is unlikely to scale up Navi for the enthusiast segment, and that the Vega-based Radeon VII will continue to be the company's flagship product. On the topic of Radeon VII custom designs, Sapphire commented that "there is no plans for that". On the other hand, Sapphire is actively working on custom designs for the Navi architecture, and mentioned that "work on a "Toxic" version of Navi is complete, and it is watercooled". Many people have speculated that AMD will unveil Navi at its Computex keynote address on May 27. Sapphire confirmed that date, and also added that the launch will be on 7th of July, 2019.

After a 4 Year Leave, AMD Rejoins the Fortune 500 List

The Fortune 500 lists the top 500 companies in the worold in terms of revenue. These are the most significant movers in the markets, be it of real estate, mining, hedge fund, or semiconductor nature (among others). AMD was "kicked" out of the Fortune 500 back in 2015, when the company was struggling with its Bulldozer-based processors and had an increasingly small marketshare - and thus revenue - that Zen came on to save. Now, thanks to the efforts of everyone involved in the company, they've been listed again on the #460 spot.

The company has been winning minds and wallets when it comes to their CPU solutions in both the mainstream and professional segments, with the company making very important forays into the HPC world mostly thanks to the strength of their CPU lineup - which, in some cases, like with the Frontier Supercomupter (expected to be the world's fastest), can bring wins in the GPU computing department as well. For comparison's sake, Intel stands at a commanding #43, while NVIDIA enjoys a comfortable #268 place.

MSI X570 MPG Motherboards Leaked: Gaming Pro Carbon, Gaming Plus

The folks over at Videocardz have treated us to a leak on MSI's upcoming X570 motherboards. The company's mid-tier MPG motherboards usually include the likes of the Gaming Carbon and Gaming Plus motherboards, and this round of motherboard development is no different. Both motherboards join leaked designs from other brands that showed active cooling being mounted on top of the chipset, a throwback to another era.

The leaked Gaming Plus is the lower-tier of the two leaked solutions of today, cutting on reinforcements on some expansion ports (such as the PCIe 16x slot). The Gaming Pro Carbon features a fancier design (with RGB lighting); the chipset hroud also serves as cooling for M.2 slots you can populate underneath (or so it seems). The Gaming Pro Carbon has more attention to detail on the placement of connectors such as SATA, and seems to have a slight advantage on the overall motherboard power delivery circuits, but these are just being eyeballed. One thing we can see is that while the Gaming Pro Carbon features MSI's Audio Boost feature, the Gaming Plus doesn't. Expect more details to be available closer to launch.

AMD to Detail Zen 2, Navi Architectures Come Hot Chips in August

The Hot Chips conference is one of the leading-edge grounds for discussion of new silicon-bound technologies, and AMD will, as usual, take to its grounds in an effort to detail their efforts in their technology fields. The conference's organization has already confirmed a number of participants in its conference schedule, which includes the likes of Intel, Microsoft, Alibaba, NVIDIA, Tesla and of course, AMD.

AMD will be delivering two keynotes: the first, on August 19th, is simply titled "Zen 2", and will therefore deal with the underpinnings of the Zen 2 microarchitecture, which will be pervasive to all of AMD's CPU product lines. A second conference will be held on the same day by AMD's CEO Lisa Su herself, and is titled "Delivering the Future of High-Performance Computing with System, Software and Silicon Co-Optimization". On the next day, August 20th, another AMD keynote is simply titled "7 nm Navi GPU", and we expect it to follow in the footsteps of the Zen 2 conference. So, with AMD diving deep into both architectures come August... it's extremely likely the company will have launched both product lines by then. Fingers crossed. You can find the abstract on AMD's CEO Lisa Su's conference after the break.

AMD Ryzen "Picasso" APU Clock Speeds Revealed

AMD is giving finishing touches to its Ryzen 3000 "Picasso" family of APUs, and Thai PC enthusiast TUM_APISAK has details on their CPU clock speeds. The Ryzen 3 3200G comes with 3.60 GHz nominal clock-speed and 4.00 GHz maximum Precision Boost frequency; while the Ryzen 5(?) 3400G ships with 3.70 GHz clock speeds along with 4.20 GHz max Precision Boost. The "Picasso" silicon is an optical shrink of the 14 nm "Raven Ridge" silicon to the 12 nm FinFET process at GlobalFoundries, the same one on which AMD builds "Pinnacle Ridge" and "Polaris 30."

Besides the shrink to 12 nm, "Picasso" features upgraded "Zen+" CPU cores that have improved Precision Boost algorithm and faster on-die caches, which contribute to a roughly 3% increase in IPC on "Pinnacle Ridge," but significantly improved multi-threaded performance compared to 1st generation Ryzen. Clock speeds of both the CPU cores and the integrated "Vega" iGPU are expected to increase. Both the 3200G and 3400G see a 100 MHz increase in nominal clock-speed, and 300 MHz increase in boost clocks, over the chips they succeed, the 2200G and 2400G, respectively. The iGPU is rumored to receive a similar 100-200 MHz increase in engine clock.

AMD Confirms Launch of Next-gen Ryzen, EPYC and Navi for Q3

During AMD's annual shareholder meeting today, AMD president and CEO Dr. Lisa Su confirmed the launch of next-generation AMD Ryzen, EPYC CPUs and Navi GPUs for the third quarter of this year. The expected products are going to be manufactured on TSMC's 7 nm process and will be using new and improved architectures.

Ryzen 3000 series CPUs are rumored to have up to as much as 16 cores in Ryzen 9 SKUs, 12 cores in Ryzen 7 SKUs and 8 cores in Ryzen 5 SKUs. EPYC server CPUs will be available in models up to 64 cores. All of the new CPUs will be using AMD "Zen 2" architecture that will offer better IPC performance and, as rumors suggest for consumer models, are OC beasts. Navi GPUs are the new 7 nm GPUs that are expected to be very competitive both price and performance wise to NVIDIA's Turing series, hopefully integrating new technologies such as dedicated Ray Tracing cores for higher frame rates in Ray Tracing enabled games. No next generation ThreadRipper launch date was mentioned, so we don't yet know when and if that will that land.

AMD Confirms its Processors are Unaffected by RIDL and Fallout Vulnerabilities

AMD in a statement confirmed that its processors are unaffected by the RIDL (Rogue In-Flight Data Load) and Fallout vulnerabilities. The company however worded its statement in CYA language, just to be safe. "...we believe our products are not susceptible to 'Fallout' or 'RIDL' because of the hardware protection checks in our architecture. We have not been able to demonstrate these exploits on AMD products and are unaware of others having done so," reads the AMD statement put out late Tuesday (14th May).

AMD came to these conclusions on the basis of its own testing and discussions with the researchers who discovered RIDL. It's important to note here, that the "Fallout" vulnerability AMD is referring to in this statement is the one which is part of four MDS vulnerabilities Intel disclosed yesterday, and not the identically named "Fallout" vulnerability discovered by CTS Labs in 2018, allegedly affecting secure memory management of AMD "Zen" processors.

AMD Releases Radeon Software Adrenalin 19.5.1 Drivers

Just in time for the release of Bethesda's open-world first-person shooter Rage 2 (find our performance analysis here), AMD has released their latest installment of the Radeon Adrenalin 2019 edition drivers for their graphics cards to make the most of the game. Indeed, AMD claims an improvement in game performance of up to 16% on the Radeon VII relative to last month's 19.4.3 drivers, and this is in addition to added support for the big Windows 10 May 2019 update and instruction tracing for AMD's GPU Profiler version 1.5.X. There is a plethora of fixed issues listed as well, and the usual list of known bugs, all of which can be seen past the break. We have also hosted the drivers installer for your convenience, which can be found at the link below.

AMD Readies Radeon RX 640, an RX 550X Re-brand

One of our readers discovered an interesting entry in the INF file of AMD's Adrenalin 19.4.3 graphics drivers. It includes two instances of "Radeon RX 640," and has the same device ID as the Radeon RX 550X from the current generation. The branding flies in the face of reports suggesting that with its next-generation "Navi" GPUs, AMD could refresh its client-segment nomenclature to follow the "Radeon RX 3000" series, but it's possible that the RX 600 series was carved out to re-brand the existing "Polaris" based low-end chips one step-down (i.e. RX 550X re-branding as RX 640, RX 560 possibly as RX 650, etc.).

The move to create the RX 600 series could also be driven by AMD's need to contain all "Navi" based SKUs in the RX 3000 series, and re-branded "Polaris" based ones in the RX 600, so that, at least initially, consumers aren't led to believe they're buying a re-branded "Polaris" SKU opting for an RX 3000-series graphics card. It's also possible that AMD may not create low-end chips based on "Navi" initially, and focus on the performance-segment with the highest sale volumes among serious gamers, the $200-400 price-range. Based on the 14 nm "Lexa" silicon, the RX 550X is equipped with 640 stream processors, 32 TMUs, 16 ROPs, and 2 GB of GDDR5 memory across a 128-bit wide memory bus. Given the performance gains expected from Intel's Gen11 "Ice Lake" iGPU and AMD's own refreshed "Picasso" APU, the RX 640 could at best be a cheap iGPU replacement for systems that lack it.

BIOSTAR Racing X570GT8 Zen 2 Motherboard Pictured and Detailed

MSI, without naming its product, teased its MEG X570 Ace motherboard late last week, obeying the cardinal rules of a teaser, such as not putting out clear pictures or names. BIOSTAR probably wanted to do something similar, but ended up leaking glaring details and pictures of its flagship socket AM4 motherboard based on the AMD X570 chipset, the Racing X570GT8. The X570 is AMD's first in-house design chipset for the AM4 socket after "Promontory" and FM2-based "Bolton," supplied by ASMedia. It was necessitated by the need to get downstream PCIe connectivity from the chipset to be certified for the latest generations (gen 3.0 or later), by AMD, and overcome many of the connectivity limitations of ASMedia "Promontory," from which AMD carved out previous socket AM4 chipsets.

Design compulsions of being a flagship product aside, there are signs of a clear focus on strengthening the CPU VRM on the Racing X570GT8, to cope with the rumored Ryzen 9 series 16-core "Zen 2" processor. The board draws power from a combination of 24-pin ATX and 8+4 pin EPS connectors, conditioning it for the processor with a 12-phase VRM. There are two metal-reinforced PCI-Express x16 slots wired to the AM4 SoC, and we get the first glimpse of the PCI-Express gen 4.0 lane switching and re-driver circuitry. We haven't seen anything to suggest that the downstream PCIe lanes from the X570 chipset are gen 4.0, yet, but we expect them to at least be gen 3.0. The presence of three M.2 slots bodes well for the downstream PCIe lane count. ASMedia "Promontory" puts out a paltry eight gen 2.0 lanes. It's also interesting to see an active fan-heatsink cooling the X570 chipset, indicating a rather high TDP compared to the 3-5 Watt TDP of the 400-series "Promontory" low-power variant chipsets. The component choices by BIOSTAR look premium and are a callback to its T-Power glory days enthusiasts remember.

AMD Ryzen 3000 "Zen 2" a Memory OC Beast, DDR4-5000 Possible

AMD's 3rd generation Ryzen (3000-series) processors will overcome a vast number of memory limitations faced by older Ryzen chips. With Zen 2, the company decided to separate the memory controller from the CPU cores into a separate chip, called "IO die". Our resident Ryzen memory guru Yuri "1usmus" Bubliy, author of DRAM Calculator for Ryzen, found technical info that confirms just how much progress AMD has been making.

The third generation Ryzen processors will be able to match their Intel counterparts when it comes to memory overclocking. In the Zen 2 BIOS, the memory frequency options go all the way up to "DDR4-5000", which is a huge increase over the first Ryzens. The DRAM clock is still linked to the Infinity Fabric (IF) clock domain, which means at DDR4-5000, Infinity Fabric would tick at 5000 MHz DDR, too. Since that rate is out of reach for IF, AMD has decided to add a new 1/2 divider mode for their on-chip bus. When enabled, it will run Infinity Fabric at half the DRAM actual clock (eg: 1250 MHz for DDR4-5000).

MSI Teases MEG X570 Ace Motherboard for Zen 2

With the 2019 Computex almost upon us, motherboard vendors are ready with socket AM4 motherboards based on AMD X570 chipset, which launches alongside the company's first wave of 3rd generation Ryzen "Matisse" processors based on the 7 nm "Zen 2" architecture. MSI put out a teaser animation of its flagship motherboard based on the AMD X570, the MEG X570 Ace. MEG, or MSI Extreme Gaming, is the company's top tier of client-segment motherboards, positioned above MPG (MSI Performance Gaming), and MAG (MSI Arsenal Gaming). Within MEG, MSI has three known sub-brands, GODLIKE, Creation, and Ace. The MEG Ace brand is the cheapest of the three, and designed to offer the most high-end features at its price-point.

Given that the company is teasing a MEG Ace product, it could be testing the waters with "Zen 2," and probably begin working on a GODLIKE product only if these processors establish a superiority over not just the i9-9900K, but also the upcoming 10-core "Comet Lake" chip. AMD's flagship is rumored to be the Ryzen 9 3850X, a mammoth 16-core/32-thread chip clocked up to 5.10 GHz. The "5 6 7" artwork with interposing "3000" indicate three distinct things: The highlighted "6" indicates onboard 802.11ax (Wi-Fi 6) controller. The 5 and 7 could indicate the X570 chipset. The "3000" of course references Ryzen 3000 series.

AMD Ryzen 9 3000 is a 16-core Socket AM4 Beast

AMD is giving finishing touches to its 3rd generation Ryzen socket AM4 processor family which is slated for a Computex 2019 unveiling, followed by a possible E3 market availability. Based on the "Matisse" multi-chip module that combines up to two 8-core "Zen 2" chiplets with a 14 nm I/O controller die, these processors see a 50-100 percent increase in core-counts over the current generation. The Ryzen 5 series now includes 8-core/16-thread parts, the Ryzen 7 series chips are 12-core/24-thread, while the newly created Ryzen 9 series (designed to rival Intel Core i9 LGA115x), will include 16-core/32-thread chips.

Thai PC enthusiast TUM_APISAK confirmed the existence of the Ryzen 9 series having landed himself with an engineering sample of the 16-core/32-thread chip that ticks at 3.30 GHz with 4.30 GHz Precision Boost frequency. The infamous Adored TV leaks that drew the skeleton of AMD's 3rd generation Ryzen roadmap, referenced two desktop Ryzen 9 parts, the Ryzen 9 3800X and Ryzen 9 3850X. The 3800X is supposed to be clocked at 3.90 GHz with 4.70 GHz boost, with a TDP rating of 125W, while the 3850X tops the charts at 4.30 GHz base and a staggering 5.10 GHz boost. The rated TDP has shot up to 135W. We can now imagine why some motherboard vendors are selective with BIOS updates on some of their lower-end boards. AMD is probably maximizing the clock-speed headroom of these chips out of the box, to preempt Intel's "Comet Lake" 10-core/20-thread processor.

BIOSTAR Presents Energy-Efficient and Compact A68N-2100E For Home and Business

Intel Switches Gears to 7nm Post 10nm, First Node Live in 2021

Intel's semiconductor manufacturing business has had a terrible past 5 years as it struggled to execute its 10 nanometer roadmap forcing the company's processor designers to re-hash the "Skylake" microarchitecture for 5 generations of Core processors, including the upcoming "Comet Lake." Its truly next-generation microarchitecture, codenamed "Ice Lake," which features a new CPU core design called "Sunny Cove," comes out toward the end of 2019, with desktop rollouts expected 2020. It turns out that the 10 nm process it's designed for, will have a rather short reign at Intel's fabs. Speaking at an investor's summit on Wednesday, Intel put out its silicon fabrication roadmap that sees an accelerated roll-out of Intel's own 7 nm process.

When it goes live and fit for mass production some time in 2021, Intel's 7 nm process will be a staggering 3 years behind TSMC, which fired up its 7 nm node in 2018. AMD is already mass-producing CPUs and GPUs on this node. Unlike TSMC, Intel will implement EUV (extreme ultraviolet) lithography straightaway. TSMC began 7 nm with DUV (deep ultraviolet) in 2018, and its EUV node went live in March. Samsung's 7 nm EUV node went up last October. Intel's roadmap doesn't show a leap from its current 10 nm node to 7 nm EUV, though. Intel will refine the 10 nm node to squeeze out energy-efficiency, with a refreshed 10 nm+ node that goes live some time in 2020.

Crytek's Hardware-Agnostic Raytracing Scene Neon Noir Performance Details Revealed

Considering your reaction, you certainly remember Crytek's Neon noir raytracing scene that we shared with you back in march. At the time, the fact that raytracing was running at such mesmerizing levels on AMD hardware was arguably the biggest part of the news piece: AMD's Vega 56 graphics card with no dedicated raytracing hardware, was pushing the raytraced scene in a confident manner. Now, Crytek have shared some details on how exactly Neon noir was rendered.

The AMD Radeon Vega 56 pushed the demo at 1080p/30 FPS, with full-resolution rendering of raytraced effects. Crytek further shared that raytracing can be rendered at half resolution compared to the rest of the scene, and that if they did so on AMD's Vega 56, they could push a 1440p resolution at 40+ FPS. The raytraced path wasn't running on any modern, lower-level API, such as DX12 or Vulkan, but rather, on a custom branch of Crytek's CryEngine, version 5.5.

Lenovo Launches New ThinkPad Laptops Based on New AMD Ryzen PRO processors

Lenovo has released a trio of new Windows 10 laptops based on new, 2nd generation AMD Ryzen PRO processors, in their famous ThinkPad form factor. There are two models that are part of the T series of ThinkPads, while one is part of X series. For reminding, the T series is the flagship line that offers the best balance between ruggedness, features, processing power, and portability in a 14 or 15-inch unit, while the X series focuses on portability.

The new ThinkPads use the second generation of AMD Ryzen PRO processors, which are 12nm improvements of the previous 14nm Ryzen Family. They carry the 3000 name branding but are similar to the 2000 series of desktop CPUs.

Some AMD Processors Have a Hardware RNG Bug, Losing Randomness After Suspend Resume

Red Hat Systemd (system and service manager) lead developer Lennart Poettering discovered that AMD A6-6310 "Beema" SoC that's popular among low-cost notebooks, has a faulty implementation of the RdRand random-number generation instruction. The processor's hardware random number generator (RNG) loses "randomness" after the machine resumes from a suspended state (i.e. waking up the notebook from sleep by opening its lid while it's powered on). Modern computers rely on RNGs for "entropy," critical to generation of unpredictable keys on the fly for SSL. However, the entropy source needn't be hardware, and isn't so by default. Software RNGs exist, and by default the Linux kernel does not use RdRand to generate entropy. Windows is not known to use RdRand for basic ACPI functions such as suspend/resume; however a faulty hardware RNG is not without implications for the platform, and applications that run on it.

Users on GitHub and Bugzilla report that with this bug, you cannot make a machine suspend a second time after waking it up from a suspended state, if your kernel uses RdRand. Commit cc83d51 to Systemd introduced optional randomness generation based on RdRand instruction. So, if RdRand instruction is present, it is used to generate UUIDs for invocation IDs. Michael Larabel of Phoronix comments that the RdRand bug is only found on older generations of AMD processors, "Excavator" and older; and does not affect the latest "Zen" processors. This bug report chronicles what's wrong with RdRand on the affected processors, as does this Linux kernel bugzilla thread. By avoiding RdRand usage on the system as part of generating a UUID, the reported systemd issue no longer happens. Red Hat is working on a solution to this bug.

AMD Collaborates with US DOE to Deliver the Frontier Supercomputer

The U.S. Department of Energy today announced a contract with Cray Inc. to build the Frontier supercomputer at Oak Ridge National Laboratory, which is anticipated to debut in 2021 as the world's most powerful computer with a performance of greater than 1.5 exaflops.

Scheduled for delivery in 2021, Frontier will accelerate innovation in science and technology and maintain U.S. leadership in high-performance computing and artificial intelligence. The total contract award is valued at more than $600 million for the system and technology development. The system will be based on Cray's new Shasta architecture and Slingshot interconnect and will feature high-performance AMD EPYC CPU and AMD Radeon Instinct GPU technology.

AMD Radeon RX 3080 XT "Navi" to Challenge RTX 2070 at $330

Rumors of AMD's next-generation performance-segment graphics card are gaining traction following a leak of what is possibly its PCB. Tweaktown put out a boatload of information of the so-called Radeon RX 3080 XT graphics card bound for an 2019 E3 launch, shortly after a Computex unveiling. Based on the 7 nm "Navi 10" GPU, the RX 3080 XT will feature 56 compute units based on the faster "Navi" architecture (3,584 stream processors), and 8 GB of GDDR6 memory across a 256-bit wide memory bus.

The source puts out two very sensational claims: one, that the RX 3080 XT performs competitively with NVIDIA's $499 GeForce RTX 2070; and two, that AMD could start a price-war against NVIDIA by aggressively pricing the card around the $330 mark, or about two-thirds the price of the RTX 2070. Even if either if not both hold true, AMD will fire up the performance-segment once again, forcing NVIDIA to revisit the RTX 2070 and RTX 2060.

ASRock Releases Next-gen AMD CPU BIOS Updates for Socket AM4 Motherboards

ASRock has announced BIOS updates for AMD X470/B450/X370/B350 and A320 series motherboards to support the soon to be released new AMD Ryzen processors.
