AMD is Preparing RDNA-Based Cryptomining GPU SKUs

Back in February, NVIDIA has announced its GPU SKUs dedicated to the cryptocurrency mining task, without any graphics outputs present on the chips. Today, we are getting information that AMD is rumored to introduce its own lineup of graphics cards dedicated to cryptocurrency mining. In the latest patch for AMD Direct Rendering Manager (DRM), a subsystem of the Linux kernel responsible for interfacing with GPUs, we see the appearance of the Navi 12. This GPU SKU was not used for anything except Apple's Mac devices in a form of Radeon Pro 5600M GPU. However, it seems like the Navi 12 could join forces with Navi 10 GPU SKU and become a part of special "blockchain" GPUs.

Way back in November, popular hardware leaker, KOMACHI, has noted that AMD is preparing three additional Radeon SKUs called Radeon RX 5700XTB, RX 5700B, and RX 5500XTB. The "B" added to the end of each name is denoting the blockchain revision, made specifically for crypto-mining. When it comes to specifications of the upcoming mining-specific AMD GPUs, we know that both use first-generation RDNA architecture and have 2560 Stream Processors (40 Compute Units). Memory configuration for these cards remains unknown, as AMD surely won't be putting HBM2 stacks for mining like it did with Navi 12 GPU. All that remains is to wait and see what AMD announces in the coming months.

Intel Gives its First Comments on Apple's Departure from x86

Apple on Monday formalized the beginning of its departure from Intel x86 machine architecture for its Mac computers. Apple makes up to 4 percent of Intel's annual CPU sales, according to a MarketWatch report. Apple is now scaling up its own A-series SoCs that use Arm CPU cores, up to performance levels relevant to Macs, and has implemented support for not just new and upcoming software ported to the new Arm machine architecture, but also software over form the iOS and iPadOS ecosystems on Mac, starting with its MacOS "Big Sur" operating system. We reached out to Intel for some of its first comments on the development.

In a comment to TechPowerUp, an Intel spokesperson said "Apple is a customer across several areas of our business, and we will continue to support them. Intel remains focused on delivering the most advanced PC experiences and a wide range of technology choices that redefine computing. We believe Intel-powered PCs—like those based on our forthcoming Tiger Lake mobile platform—provide global customers the best experience in the areas they value most, as well as the most open platform for developers, both today and into the future."

AMD Radeon Pro 5600M with HBM2 Benchmarked

Benchmarks of the new Apple-exclusive AMD Radeon Pro 5600M graphics solution by Max Tech reveals that the new GPU is about 50% faster than the Radeon Pro 5500M, and within striking distance of the Radeon Pro Vega 48 found in Apple's 5K iMacs. The Pro 5600M is an Apple-exclusive solution by AMD, based on the "Navi 12" silicon that features a 7 nm GPU die based on the RDNA graphics architecture, flanked by two 4 GB HBM2 memory stacks over a 2048-bit interface. The GPU die features 2,560 stream processors, but clocked differently from Radeon Pro discrete graphics cards based on the "Navi 10" ASIC that uses conventional GDDR6.

The Radeon Pro 5600M solution was found to be 50.1 percent faster than the Radeon Pro 5500M in Geekbench 5 Metal (another Apple-exclusive SKU found in 16-inch MacBook Pros), and just 12.9 percent behind the Radeon Vega 48. The Vega 56 found in iMac Pro is still ahead. Unigine Heaven sees the Pro 5600M being 48.1% faster than the Pro 5500M, and interestingly, faster than Vega 48 by 11.3%. With 2,560 RDNA stream processors, you'd expect more performance, but this card was designed to meet stringent power limits of 50 W, and has significantly lower clock-speeds than "Navi 10" based Radeon Pro graphics cards (1035 MHz max boost engine clock vs. 1930 MHz and 205 W TDP of the Pro W5700). Find more interesting commentary in the Max Tech video presentation.

AMD "Navi 12" Silicon Powering the Radeon Pro 5600M Rendered

Out of the blue, AMD announced its Radeon Pro 5600M mobile discrete graphics solution exclusive for Apple's 16-inch MacBook Pro. It turns out that the Pro 5600M is based on an all new ASIC by AMD, codenamed "Navi 12." This is a multi-chip module, much like "Vega 20," featuring a 7 nm GPU die and two 16 Gbit (4 GB) HBM2 memory stacks sitting on an interposer. While the actual specs of the GPU die on the "Navi 14" aren't known, on the Pro 5600M, it is configured with 40 RDNA compute units amounting to 2,560 stream processors, 160 TMUs, and possibly 64 ROPs.

The engine clock of the Pro 5600M is set at up to 1035 MHz. The HBM2 memory is clocked at 1.54 Gbps, which at the 2048-bit bus width, translates to 394 GB/s of memory bandwidth. There are two big takeaways from this expensive-looking ASIC design: a significantly smaller PCB footprint compared to a "Navi 10" ASIC with its eight GDDR6 memory chips; and a significantly lower power envelope. AMD rates the typical power at just 50 W. In the render below, the new ASIC is shown next to a "Navi 14" ASIC that power RX/Pro 5500-series SKUs.

AMD "Navi 14" and "Navi 12" GPUs Detailed Some More

The third known implementation of AMD's "Navi" generation of GPUs with RDNA architecture is codenamed "Navi 14." This 7 nm chip is expected to be a cut-down, mainstream chip designed to compete with a spectrum of NVIDIA GeForce GTX 16-series SKUs, according to a 3DCenter.org report. The same report sheds more light on the larger "Navi 12" GPU that could power faster SKUs competing with the likes of the GeForce RTX 2080 and RTX 2080 Super. The two follow the July launch of the architecture debut with "Navi 10." There doesn't appear to be any guiding logic behind the numerical portion of the GPU codename. When launched, the pecking order of the three Navi GPUs will be "Navi 12," followed by "Navi 10," and "Navi 14."

"Navi 14" is expected to be the smallest of the three, with an estimated 170 mm² die-area, about 24 RDNA compute units (1,536 stream processors), and expected to feature a 128-bit wide GDDR6 memory interface. It will be interesting to see how AMD carves out an SKU that can compete with the GTX 1660 Ti, which has 6 GB of 192-bit GDDR6 memory. The company would have to wait for 16 Gbit (2 GB) GDDR6 memory chips, or piggy-back eight 8 Gbit chips to achieve 8 GB, or risk falling short of recommended system requirements of several games at 1080p, if it packs just 4 GB of memory.

Radeon RX 5300 XT and AMD B550 Chipset Coming to OEM Systems in October

HP has listed new desktop consumer prebuilts that use previously unannounced hardware from AMD, namely the Radeon RX 5300 XT graphics card and the B550 chipset. B550 has been expected for a while — it's a lower-cost chipset for Ryzen 3000 "Zen 2" processors with reduced feature set. HP calls the chipset "AMD Promontory B550A" in their sheets which seems to be designed and produced by ASMedia (unlike X570, which is a fully AMD in-house design). One of the major differences between X570 and B550 is that the latter has no support for PCI-Express 4.0, which won't matter one bit in its target segment. This move not only reduces chipset cost, it also drives down the cost of motherboards significantly, as the more stringent signal integrity requirements for PCIe 4.0 won't apply here.

While we have heard rumors that AMD is working on a smaller chip for their "Navi" architecture (Navi 12 and Navi 14), it's uncertain whether RX 5300 XT is really based on Navi, or whether it will be yet another rebrand — we wouldn't be surprised if Polaris is making a comeback yet again. Both systems are listed for € 699 and € 899, with shelf availability expected for October 8th.

AMD Updates Roadmaps to Lock RDNA2 and Zen 3 onto 7nm+, with 2020 Launch Window

AMD updated its technology roadmaps to reflect a 2020 launch window for its upcoming CPU and graphics architectures, "Zen 3" and RDNA2. The two will be based on 7 nm+ , which is AMD-speak for the 7 nanometer EUV silicon fabrication process at TSMC, that promises a significant 20 percent increase in transistor-densities, giving AMD high transistor budgets and more clock-speed headroom. The roadmap slides however hint that unlike the "Zen 2" and RDNA simultaneous launch on 7th July 2019, the next-generation launches may not be simultaneous.

The slide for CPU microarchitecture states that the design phase of "Zen 3" is complete, and that the microarchitecture team has already moved on to develop "Zen 4." This means AMD is now developing products that implement "Zen 3." On the other hand, RDNA2 is still in design phase. The crude x-axis on both slides that denotes year of expected shipping, too appears to suggest that "Zen 3" based products will precede RDNA2 based ones. "Zen 3" will be AMD's first response to Intel's "Comet Lake-S" or even "Ice Lake-S," if the latter comes to fruition before Computex 2020. In the run up to RDNA2, AMD will scale up RDNA a notch larger with the "Navi 12" silicon to compete with graphics cards based on NVIDIA's "TU104" silicon. "Zen 2" will receive product stack additions in the form of a new 16-core Ryzen 9-series chip later this month, and the 3rd generation Ryzen Threadripper family.

AMD Could Launch New Navi GPUs Soon

AMD's president and CEO Dr. Lisa Su was talking during AMD's Q2 earnings Q&A conference and got asked a very interesting question. When prompted about high end Navi GPUs, Dr. Su answered with "I would say they are coming. You should expect that our execution on those are on track and we have a rich 7 nm portfolio beyond the products that we have already announced in the upcoming quarters."

This answer gives us hope to see more powerful Navi GPUs possibly by the end of the year, meaning that AMD's answer to Turing is almost ready. As we saw earlier in the rumors, we might get additional higher end GPU models in form of alleged RX 5800 and RX 5900, with XT variants available for both of those models. The RX 5800 is supposed to utilize a new GPU core called Navi 12, while the core for RX 5900 is still unknown.

AMD Readies Larger 7nm "Navi 12" Silicon to Power Radeon RX 5800 Series?

AMD is developing a larger GPU based on its new "Navi" architecture to power a new high-end graphics card family, likely the Radeon RX 5800 series. The codename "Navi 12" is doing rounds on social media through familiar accounts that have high credibility with pre-launch news and rumors. The "Navi 10" silicon was designed to compete with NVIDIA's "TU106," as its "XT" and "Pro" variants outperform NVIDIA's original RTX 2060 and RTX 2070, forcing it to develop the RTX 20 Super series, by moving up specifications a notch.

Refreshing its $500 price-point was particularly costly for NVIDIA, as it was forced to tap into the 13.6 billion-transistor "TU104" silicon to carve out the RTX 2070 Super; while for the RTX 2060 Super, it had to spend 33 percent more on the memory chips. With the "Navi 12" silicon, AMD is probably looking to take a swing at NVIDIA's "TU104" silicon, which has been maxed out by the RTX 2080 Super, disrupting the company's $500-700 lineup once again, with its XT and Pro variants. There's also a remote possibility of "Navi 12" being an even bigger chip, targeting the "TU102."
