Back in October following the launch of the EPYC 9005 "Turin" processors I ran an AVX-512 performance comparison for the EPYC 9755 with 512-bit data path vs. 256-bit data path vs. AVX-512 disabled. That was interesting for showing the benefits of Zen 5's full 512-bit data path support compared to the "double pumped" approach with Zen 4 or optionally used via a BIOS option on Zen 5. AVX-512 continues to prove to be very performant and power efficient with AMD Zen 5 processors unlike with the early generations of AVX-512 on Intel processors. Here is a fresh look at the AVX-512 performance on a Supermicro server with an AMD EPYC 9655 processor.

One of the important pieces of open-source software still working toward proper Wayland support is the Chromium Embedded Framework "CEF" that in turn is depended upon by software like Steam, OBS Studio, Spotify, and many other software packages for having an in-app browser-type experience. The good news is there has been some recent progress on native Wayland support for CEF...

Intel Co-CEO Michelle Johnston Holthaus announced during their Q4 earnings call this evening that they will not be bringing their "Falcon Shores" AI / HPC chip to market. Falcon Shores was to be their next-gen GPU accelerator to effectively succeed their Gaudi AI chips. Instead Falcon Shores will be used as an internal test vehicle while preparing the hardware/software ecosystem for Jaguar Shores as its successor...

Over the past week I have published a number of GeForce RTX 5090 Linux compute benchmarks as well as the GeForce RTX 5080 on Linux. With that early NVIDIA R570 Linux driver build as part of the CUDA 12.8 package I was asked to wait on Linux gaming benchmarks until the proper RTX 50 Linux driver is released. Well, it was released this morning with the NVIDIA 570.86.16 Linux beta availability and have in turn been pushing the GeForce RTX 5080 and RTX 5090 through a number of Linux gaming/graphics benchmarks.

Last week saw the big set of Bcachefs updates merged for the Linux 6.14 kernel that included the last anticipated big on-disk format change as well as scalability improvements. It was a particularly big pull after Bcachefs missed out on any changes being upstreamed for Linux 6.13. This week a set of follow-on fixes/improvements have been merged for this experimental copy-on-write file-system...
