Last week we looked at the Windows vs. Linux performance on the AMD Ryzen 9 5900X where there was some very friendly competition and much closer results than we are used to seeing for modern, high-end x86_64 processors between the two operating systems. As a follow-up to that testing, here are results of Windows 10 October 2020 Update with Windows Subsystem for Linux (both WSL1 and WSL2) compared to the performance in turn off bare metal Ubuntu 20.04.1 LTS and Ubuntu 20.10 on the same system.

While the talk in recent weeks has been about the performance of Apple's M1 ARM chip and then rumors there might be a 32 core chip in the pipe, there is already something much stronger: Ampere Altra has begun shipping and its flagship 80-core SoC with up to two sockets per server can easily take on the AMD EPYC 7742 "Rome" and Intel Xeon Platinum 8280 "Cascade Lake" performance across a variety of workloads. Here is our initial look at the Ampere Altra performance on Linux in our independent performance benchmarks.

Initially found with "Elkhart Lake" SoCs and likely to be found on further future Intel client SoCs is the integrated memory controller supporting in-band ECC (IBECC). Coming with Linux 5.11 is the "IGEN6" EDAC driver for handling this error detection and correction on Intel SoCs sporting IBECC...

Back in October Intel announced Iris Xe MAX as discrete graphics for laptops. The overall Linux state for Xe MAX hasn't been too clear and we haven't had any hardware access to this Intel laptop discrete graphics hardware to report our own findings, but their developers have now cleared up the situation. The good news is the Xe MAX graphics can be used for a GPU-accelerated Linux virtual machine. The bad news is the Xe MAX support doesn't yet allow for dGPU usage by the host outside of a virtual machine context as it needs "two different [Linux] kernels" for operation in conjunction with the integrated graphics...
