With the recently released AMD ROCm 6.4 release for this open-source GPU compute stack for Radeon and Instinct hardware there are yet more indications around AMD's growing software ecosystem expansion. With ROCm 6.4 are additions to the HIP API for allowing linking of SPIR-V code objects, which is the intermediate representation used by Vulkan as well as with OpenCL and other Khronos APIs...

GCC Patch Revived For -mtune=generic Showing Nice Benefits On Intel & AMD CPUs

Phoronix - Tue, 04/22/2025 - 01:26
A 2021 era patch for the GNU Compiler Collection (GCC) has been revived and discussed in recent days around simplifying the memcpy and memset inlining strategies when compiling code with the "-mtune=generic" option. The patch takes the approach during that generic tuning to try to avoid branches. In doing so, some nice performance benefits are observed in some benchmarks...

Ubuntu 25.04 vs. Windows 11 CPU Performance For The AMD Ryzen AI 7 PRO 360

Earlier this month was a look at the AMD RDNA 3.5 graphics between Windows 11 and Ubuntu 25.04 using a Ryzen AI 7 PRO 360 "Strix Point" SoC within a Lenovo ThinkPad T14s Gen 6. That was an interesting benchmark battle and providing a fresh look at the open-source AMD Linux graphics driver stack relative to Radeon Software on Windows. For those curious about the current Zen 5(C) performance, today's article are all of the CPU benchmarks for the AMD Ryzen AI 7 PRO 360 performance under the newly-released Ubuntu 25.04 and Windows 11 as pre-loaded by Lenovo.
