With having a new Lenovo ThinkPad T14s Gen 6 laptop in the lab, a lot of Linux benchmarks are forthcoming from this ThinkPad laptop powered by an AMD Ryzen AI 7 PRO 360 SoC. This AMD Zen 5 SoC with Radeon 880M RDNA 3.5 integrated graphics had me curious how the Windows 11 vs. Linux iGPU performance is looking now more than a half-year after launch. Prior to blowing out the Microsoft Windows 11 Pro installation that shipped on the ThinkPad T14s Gen 6 and loaded with the latest AMD drivers and Windows 11 updates, I ran some graphics benchmarks for seeing how they stack up against the open-source AMD graphics drivers found on the brand new Ubuntu 25.04 release.

The ZLUDA open-source project for "CUDA on non-NVIDIA GPUs" continues being developed for enabling CUDA like GeekBench and AI workloads on AMD GPUs and other hardware vendors.

Last month I posted benchmarks showing the performance when using the new 3D V-Cache Optimizer driver on Linux using the flagship Ryzen 9 9950X3D. This optimizer driver allows tuning the "amd_x3d_mode" for indicating your preference for the CCD with the higher frequency or larger cache size. For some additional insight into the 3D V-Cache Optimizer driver performance impact on Linux, here are benchmarks looking at the difference while using the AMD Ryzen 9 9900X3D.

Going back to 1972 is the General Purpose Interface Bus (GPIB, a.k.a. IEEE-488) as a parallel interface bus developed by HP. GPIB pre-dates the Linux kernel itself while it wasn't until last year that the GPIB driver subsystem was added to the Linux kernel's staging area with GPIB still seeing some use by scientific equipment and other devices. For Linux 6.15, the GPIB code has seen a thorough round of code clean-ups and improvements...
