Last week AMD formally announced the Radeon RX 9070 series graphics cards that will begin shipping tomorrow at $549 for the Radeon RX 9070 and $599 for the RX 9070 XT. Today the review embargo is lifted so we can now share Linux performance benchmarks and more details on the open-source Linux driver support for these first AMD RDNA4 graphics cards.

In addition to the Radeon RX 9070 series Linux gaming/graphics benchmarks with today's embargo lift, I've also spent some time working on some GPU compute benchmarks for these first RDNA4 graphics cards. Here is a look at some initial GPU compute benchmarks of the Radeon RX 9070 and Radeon RX 9070 XT graphics cards, mostly on cross-vendor OpenCL benchmarks, and a few words on the GPU compute stack support for the Radeon RX 9070.

In addition to Vulkan-powered AI / machine learning talks at last month's Vulkanised 2025 conference, another interesting topic at this annual Vulkan developer conference was around improving the Vulkan API and making it easier for new developers and maximizing the potential with new GPU hardware...

Linux already supports a number of XP-Pen drawing tablets while the upcoming Linux 6.15 kernel is set to include support for another one: the XP-Pen Artist Pro 19. This XP-Pen Artist Pro 19 is a big, 4K resolution display drawing tablet that retails for nearly $800 USD and features dual stylus, 16K pressure levels, and a nice display for this 19-inch drawing surface...

Sven Peter continues work on upstreaming more of the Apple SoC support to the mainline Linux kernel. On the DeviceTree side following the DT support for Apple T2 SoCs sent out last month, another set of updates were submitted this week ahead of the Linux 6.15 merge window...

Released last year shortly after the EPYC 9005 "Turin" processor launch was ZenDNN 5.0 for Zen 5 optimized CPU inferencing with the likes of PyTorch and TensorFlow. ZenDNN 5.0 delivers up to a 400% performance uplift according to AMD engineers. Out today is ZenDNN 5.0.1 with further optimizations, particularly around recommendation engines and large language models (LLMs)...

Ahead of NVIDIA GeForce RTX 5070 graphics cards seeing retail availability tomorrow, today the review embargo expires on the GeForce RTX 5070 Founders Edition graphics cards. I've been testing out the GeForce RTX 5070 under Linux and today have a number of GPU compute benchmarks to share.

Open-sourced back in January was the Yandex Perforator as a new software project for uncovering code inefficiencies and potentially "save billions of dollars" in expenses. Perforator has continued evolving since its open-source announcement and out today is Perforator 0.0.5 as the latest milestone...

The AMD BC-250 is a crypto mining GPU launched by AMD back during the Bitcoin mining craze when it was profitable using GPUs for mining. At its heart is a Navi "RDNA1" GPU similar to the APU found within the Sony PlayStation 5. The AMD BC-250 can be found used these days for $50~100 USD and with the latest open-source Mesa graphics driver code for Linux systems can now be used with the Vulkan API for graphics/gaming...

While AMD hasn't released an updated Windows driver for the Radeon R9 290 "Hawaii" GPUs since 2022 for Windows 10, over in the Linux/open-source space the driver support continues. It will hopefully continue reliably too now that the Mesa RADV continuous integration (CI) has added driver testing with an old Hawaii GPU...

Going back nearly one year Intel has been working on Linux driver support for a new adaptive sharpening filter with Lunar Lake graphics. That's culminated into working on a common DRM sharpness property for communicating sharpness preferences and this week the latest patch series for that property was posted...

SiFive recently sent over their new HiFive Premier P550 developer board and as part of that fresh RISC-V CPU testing I've also been re-testing the prior SiFive HiFive Unmatched developer board from 2020~2021 for reference. Out of curiosity, I've carried out some tests using the HiFive Unmatched to look at how the Ubuntu Linus RISC-V performance has evolved from Ubuntu 21.04 when I first tested that RISC-V quad-core developer board, Ubuntu 22.04 LTS, and now the latest Ubuntu 24.04 LTS packages.

Mozilla Firefox 136.0 release binaries are now available online ahead of tomorrow's official release announcement. Particularly on the Linux side, Firefox 136 is one of the more exciting updates in recent times...

Back in December Linux kernel patches were posted by a Meta engineer for making use of the AMD INVLPGB instruction found with Zen 3 and newer processors. The Linux kernel would use INVLPGB for invalidating TLB entries for a range of pages with broadcast. After these patches went through 14 rounds of review since December, it looks like this AMD broadcast TLB invalidation support is now ready for the mainline Linux kernel!..

Raspberry Pi has been on a spree lately with many new product launches such as the Raspberry Pi 500, Raspberry Pi Monitor, Raspberry Pi 5 16GB, and Compute Module 5 in the past few months. Today the company announced an expansion of their offerings in the Compute Module 4 line-up...

Open-sourced back in 2019 was the OpenPOWER Microwatt as an open-source, soft processor core of Power ISA 3.0 and intended for use on FPGA boards and then there was seemingly short-lived work to fabricate a Microwatt chip and Microwatt also found its way for use within a BMC implementation. Linux 5.14 added support for this soft CPU core while the upcoming Linux 6.15 cycle is set to introduce SMP support for Microwatt...

The outlook for using Vulkan within machine learning software is quite positive and even able to offer similar performance to NVIDIA's prized CUDA...

Back in 2023 ONNX and AMD announced TurnkeyML as an "AI insights toolchain". There hasn't been too much news about TurnkeyML since then and they now describe the project itself as a "no-code AI toolchain" while this week brought the release of the big TurnkeyML 6.0 software...

Back during January Steam on Linux dropped by 0.23% to a 2.06% marketshare while overnight the numbers were published for February 2025.....

A pull request was sent out on Friday that could potentially land for the upcoming Linux 6.15 kernel to transition ARM's kernel entry code from some architecture-specific Assembly over to using the generic entry code path. It means more unification and transitioning some Assembly code over to C, but it also comes with some hits to performance...

Following the official SDL 3 release back in January, SDL 3.2.6 was released this weekend as the newest iteration of this widely-used software/hardware abstraction layer that is commonly leveraged by cross-platform games...

Last month I wrote about new code slated to be added for Linux 6.15 that would provide a cross-driver/standardized means of reporting to user-space over hung GPUs. For the likes of the AMD and Intel graphics drivers initially, user-space will be notified via this new wedged event when a GPU is hung in case user-space wants to take additional actions to try to recover the GPU or at least properly note the troubled state of the GPU. There are now proposed patches under review for further extending this functionality...

Last week AMD sent out a big batch of new graphics driver code for Linux 6.15 including new GPU support, OEM i2c support for RGB lighting and other features, and other updates. Another round of AMDGPU/AMDKFD feature code targeting the upcoming Linux 6.15 merge window was sent out on Friday...

A fix was merged to the Linux 6.14 kernel on Friday -- and also for back-porting to existing Linux stable kernels over the coming days -- for fixing an annoying problem with Intel Core 2 processors. The problem, which was introduced to the Linux kernel back in 2019, could lead to system stalls and boot delays for those still using Intel Core 2 CPUs with modern distributions...

While a shorter month, there were still 263 original articles published on Phoronix during February.

AMD has been investing a lot into the ROCm compute stack to make it a more formidable contender against the NVIDIA CUDA software ecosystem. From better documentation and improved application/API coverage to expanding their range of supported AMD GPUs, there's been a lot going on. So with this morning's much anticipated Radeon RX 9070 series launch announcement ahead of product availability next week, you are probably wondering about Radeon RX 9000 series support for ROCm too... Here's what I know so far...

An AMD engineer presented earlier this month at the Vulkanised 2025 conference in Cambridge (UK) around the work they are pursuing for AI using the MLIR intermediate representation, IREE, and the role that Vulkan/SPIR-V can play for AI acceleration across AMD's wares as well as other hardware...
