AMD Quietly Funded A Drop-In CUDA Implementation Built On ROCm: It's Now Open-Source
While there have been efforts by AMD over the years to make it easier to port codebases targeting NVIDIA's CUDA API to run atop HIP/ROCm, it still requires work on the part of developers. The tooling has improved such as with HIPIFY to help in auto-generating but it isn't any simple, instant, and guaranteed solution -- especially if striving for optimal performance. Over the past two years AMD has quietly been funding an effort though to bring binary compatibility so that many NVIDIA CUDA applications could run atop the AMD ROCm stack at the library level -- a drop-in replacement without the need to adapt source code. In practice for many real-world workloads, it's a solution for end-users to run CUDA-enabled software without any developer intervention. Here is more information on this "skunkworks" project that is now available as open-source along with some of my own testing and performance benchmarks of this CUDA implementation built for Radeon GPUs.
AMD Ryzen 5 8500G: A Surprisingly Fascinating Sub-$200 CPU
After reviewing the Ryzen 7 8700G and the Ryzen 5 8600G as these new Zen 4 processors with RDNA3 integrated graphics, the latest AMD 8000G series CPU in the Linux benchmarking lab at Phoronix is the Ryzen 5 8500G. The Ryzen 5 8500G is a 6-core / 12-thread processor with RDNA3 graphics that retails for just $179 USD. Here's a look at how it's performing against other AMD and Intel processors on Ubuntu Linux. The Ryzen 5 8500G ends up being decent on the GPU side but making me genuinely excited is the Zen 4C prospects in the low-power space for AI workloads at the edge, low power servers, and other different deployments for great low-power performance. Under load this AVX-512 wielding budget desktop processor was typically pulling 50 Watts or less!
Intel Core i3 14100 / i5 14500 vs. AMD Ryzen 5 8500G / 8600G In 500+ Benchmarks
As part of the recent AMD Ryzen 5 8500G and 8600G Linux reviews I ended up picking up the Core i3 14100 and Core i5 14500 Raptor Lake Refresh processors for the similarly-priced Intel competition. It's not too often receiving review samples from Intel of the lower-end processor SKUs, so I'm back around today with even more benchmarks of these lower-tier AMD and Intel processors. In this article are 500+ benchmarks looking at the CPU and iGPU performance of the Intel Core i3 14100 and Core i5 14500 processors up against the AMD Ryzen 5 8500G and Ryzen 5 8600G processors under Ubuntu Linux.
Intel Arc Graphics A580 / A750 / A770 Linux Performance For Early 2024
Earlier this week I posted a 35-way Linux graphics card comparison featuring the new NVIDIA RTX 40 SUPER graphics cards and other recent AMD and NVIDIA hardware I had available while using the latest Linux drivers. Intel Arc Graphics desktop graphics cards weren't part of that comparison for simply running out of time prior to the RTX 4080 SUPER embargo lift to facilitate that re-testing. But for those interested, here is a fresh look at the Intel Arc Graphics A580 / A750 / A770 Linux performance against those NVIDIA GeForce and AMD Radeon graphics cards on Ubuntu Linux.

All three of these new parts were re-tested at both 35 and 45 Watt cTDPs for seeing the impact on performance and power efficiency.
NVIDIA GH200 72 Core Grace CPU Performance vs. AMD Ryzen Threadripper Workstations
Earlier this month I posted some initial CPU benchmarks of the NVIDIA GH200 Grace Hopper up against AMD EPYC Zen 4 and Intel Xeon Emerald Rapids processors. That was a very interesting battle and showed the interesting capabilities of the 72 Arm Neoverse-V2 cores. With this GPTshop.ai GH200 system actually being in workstation form, I also ran some additional benchmarks looking at the CPU capabilities of the GH200 compared to AMD Ryzen Threadripper 7000 series workstations.
AMD Radeon RX 7900 GRE Linux Performance
Last July AMD launched the Radeon RX 7900 GRE graphics card in China with a reduced Navi 31 GPU. Beginning tomorrow, 27 February, the Radeon RX 7900 GRE is being made available worldwide. Today the review embargo expires on the Radeon RX 7900 GRE for the worldwide scope and within the US will be priced around $549 USD.
The Importance Of The TUXEDO Driver Package On Their Newer Ryzen Laptops
As an important notice to those with new TUXEDO laptops such as the TUXEDO Pulse 14 Gen 3 powered by the Ryzen 7 7840HS, installing their DKMS-based driver package can be very important if aiming to achieve maximum performance.
And then the most popular news for the month:
HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD
One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed.

Orange Pi Neo Coming As A Ryzen 7 + Linux Powered Handheld Device
When hearing of "Orange Pi Neo" this weekend from sources at FOSDEM 2024, I just assumed it was yet another Orange Pi single board computer... But then to hear it's a handheld game console from Orange Pi again gives off the impression of some low-power ARM device. It turns out though that the Orange Pi Neo is a forthcoming AMD Ryzen powered handheld gaming console.
Torvalds Has It With "-Wstringop-overflow" On GCC Due To Kernel Breakage
One of the new features for Linux 6.8 that was merged late was enabling the -Wstringop-overflow compiler option to warn about possible buffer overflows in cases where the compiler can detect such possible overflows at compile-time. While it's nice in theory, issues on GCC has led Linus Torvalds to disabling this compiler option as of now Linux 6.8.

X.Org Server Clears Out Remnants For Supporting Old Compilers
There are still no signs of a new X.Org Server feature release coming in the near-term with most of the major stakeholders divesting from the xorg-server besides the XWayland portion of the code-base. But for those interested in the past few days there have been some NetBSD/OpenBSD build fixes to the X.Org Server as well as clearing out some remnants of old compiler support.
Qualcomm Hardware Support Increasingly In Good Shape On The Mainline Linux Kernel
After years of work by Qualcomm and Linaro engineers, the Qualcomm SoC support on the mainline Linux kernel has finally matured enough that new hardware support tends to come rather quickly and be well supported. With the forthcoming Linux 6.8 kernel the new Snapdragon 8 Gen 3 can boot on the mainline kernel, the Snapdragon-powered ThinkPad X13s has been popular with Linux developers thanks to the upstream support, and other Qualcomm-powered devices tending to play more nicely with upstream Linux these days rather than having to resort to vendor kernel builds.

Cleaning Up A Mess: Linux 6.9 Likely To Land Rework Of x86 CPU Topology Code
Longtime Linux kernel developer Thomas Gleixner with Intel-owned Linutronix has been spending much time over the past several months reworking the Linux kernel's x86 CPU topology evaluation code. This is to clean-up a mess of aging kernel code as well as some areas of the code being incorrect in today's era of hybrid Intel Core processors with a mix of P / E cores with the E cores lacking SMT/HT and thus throwing off prior kernel assumptions. With the code now queued up in a TIP branch today, it looks like that CPU topology rework could be good to go with Linux 6.9.

AMD Zen 5 Compiler Support Posted For GCC - Confirms New AVX Features & More
Making for a very exciting Saturday morning, AMD just posted their initial enablement patch for plumbing Zen 5 processor support "znver5" into the GNU Compiler Collection! With GCC 14 due to be released as stable in March~April as usual for the annual compiler release, it's been frustrating to see no Zen 5 support even while Intel has already been working on Clear Water Forest and Panther Lake support with already having upstreamed Sierra Forest, Granite Rapids, and other new CPU targets months ago... Well, Granite Rapids was added to GCC in late 2022. But squeezing in as what should now be merged in time is the initial AMD Zen 5 support!
