The recent rumors panned out and NVIDIA just announced they have reached a definitive deal with SoftBank to acquire Arm...

Last week we reported on a Linux 5.9 kernel regression following benchmarks from Linux 5.0 to 5.9 and there being a sharp drop with the latest development kernel. That kernel regression was bisected to code introduced by Linus Torvalds at the start of the Linux 5.9 kernel cycle. Unfortunately it's not a trivial problem and one still being analyzed in coming up with a proper solution. So the short story is it's a work-in-progress while this article has some additional insight and benchmarks done over the course of the past few days.

As part of re-testing all hardware prior to major GPU/driver launches, here is a look at the latest NVIDIA OpenCL/CUDA performance on Linux -- complementing the recent Blender 2.90 benchmarks and the latest NVIDIA vs. AMD Linux gaming performance. In still waiting to find out when we will get any NVIDIA Ampere hardware for Linux testing, I have been having some benchmarking fun and extended this to a 24-way graphics card comparison back to Maxwell in looking at not only the raw GPU compute performance but also the performance-per-Watt / power consumption and GPU thermal values.

The Linux 5.0 to 5.9 kernel benchmarking posted this week showed TensorFlow Lite running slower since the Linux 5.5 kernel... On top of looking at the new Linux 5.9 regressions, I also spent some time bisecting and figuring out what happened for TensorFlow Lite last year that has at least for the system under test caused it to run slower for all the kernel releases this year as shown in the aforelinked article.
