For those wondering how the open-source Radeon Linux graphics drivers compare to the Radeon Software Windows drivers for the recently released Radeon RX 6800 XT, here are some preliminary data points looking at the OpenGL / Vulkan performance between Windows and Linux for RDNA 2.

One of the big features to look forward to with Intel's Xeon "Sapphire Rapids" is the introduction of AMX as the Advanced Matrix Extensions. While Sapphire Rapids looks to be at least one year out still, the company's open-source compiler engineers have already been hard at work on the software infrastructure support...

Back in May was AMD's celebration of the GPUOpen re-launch and that included the introduction of the Radeon Memory Visualizer (RMV) as their newest tool at the time. But rather strange for being a "GPUOpen" development tool is that it was Windows-only and not actually open-source. Today that has now changed with Radeon Memory Visualizer going open-source...

Last week AMD published their Zen 3 support for GCC code compiler. That initial support, which has already been merged into GCC 11, is the initial support flipping on newly supported instructions but not yet offering any tuned scheduler model or other optimizations compared to the existing Zen 2 path. In any case, here is a look at the performance changes with building the open-source benchmarks under test with "znver3" compared to the prior Zen 2 and Zen 1 targets along with generic x86_64 and then also looking at the performance if catering the compiler targets for Intel's Skylake and Haswell processors.

It's been just over one month since AMD launched the Ryzen 5000 series as the first processors part of the Zen 3 family. The Linux performance continues to be terrific with the Ryzen 5600X / 5800X / 5900X / 5950X parts in our continued benchmarking...
