Ahead of launch for new discrete/integrated graphics backed by open-source Linux drivers, it can often be difficult to ascertain the level of support pre-launch given the complexity of today's GPUs, we are past the days of long monolithic patch series for new hardware enablement, and also not knowing about what features may be added for the next-generation hardware. But if latest Mesa developer comments hold, it looks like for Intel Xe2 graphics the open-source Vulkan driver at least has "most" of the code now in place...

Last week I published some initial benchmarks of the Amazon/AWS Graviton4 processors now available within the EC2 cloud using the new "R8g" instances. That initial comparison was a 64 vCPU comparison of Graviton4 against AMD EPYC and Intel Xeon 64 vCPU AWS instances. In today's article is a look at the 96-core Graviton4 bare metal performance using the "r8g.metal-24xl" AWS instance type. The Graviton4 r8g.metal-24xl performance was then compared in today's article against various bare metal AMD EPYC, Ampere Altra Max, and Intel Xeon processors in the lab at Phoronix.

Toward the end of 2022 a GCC AArch64 compiler change was quietly made by Arm that allows "-march=native" to be handled on 64-bit ARM by treating it as the equivalent "-mcpu=native" option. The change happened to fly under my radar at that time and didn't draw much attention at large while now it's finally being officially documented in hopes of similar behavior being adopted by other compilers for AArch64...
