AMD Inception "SRSO" Mitigation Cleanup & Fixes Head To Linux 6.5-rc7

Posted on by

Earlier this month the AMD Inception vulnerability was disclosed and quickly mitigated within the mainline Linux kernel and back-ported to the stable kernels. In the rush to get the code merged and the mitigation being under embargo until the disclosure date, some bugs and clean-ups with the mitigation code were discovered. That revised code was now submitted today for merging ahead of the Linux 6.5-rc7 kernel release this weekend…

AMD Ryzen 7 7840U Windows 11 vs. Linux CPU Performance

Posted on by

Over the past month I’ve been delivering a number of Linux laptop tests with the AMD Ryzen 7 7840U for that Zen 4 “Phoenix” SoC within an Acer Swift Edge 16. One of the requests that has come up with my ongoing testing has been how well the default Microsoft Windows 11 installation compares to loading up Linux on this 8-core AMD Zen 4 laptop. Well, in this article is a look at the Linux performance compared to Windows 11, including when making use of the Linux 6.5 development kernel where AMD P-State is now the default and also for seeing what workloads are impacted by the recent AMD Inception vulnerability.

Firefox 117 Beta 8 vs. Google Chrome 116 Linux Browser Performance

Posted on by

Given all the interest this week in Firefox outperforming Google Chrome in SunSpider, I decided to run some fresh Linux desktop web browser benchmarks on my end. For today’s comparison is a look at the newly-released Chrome 116 up against Firefox 117b8 that will be released as stable in just over one week…

SUSE To Be Taken Private By Its Largest Shareholder

Posted on by

The SUSE organization has changed hands many times over the years… From being its own independent company to the notable acquisition by Novell two decades ago. Over the past decade SUSE has changed hands between Attachmate, Micro Focus, EQT Partners, and then went public back in 2021 on the Frankfurt Stock Exchange. Now two years later its being taken private…

AMD Isn't Done Yet Optimizing The Mesa RadeonSI Driver For Workstation OpenGL

Posted on by

While over the past several years AMD landed numerous significant improvements to their RadeonSI driver for benefiting OpenGL workstation use-cases, that quest isn’t yet over and more optimizations continue to be pursued. There are additional optimizations on the horizon for the RadeonSI Gallium3D driver for benefiting OpenGL on Linux workstations…

Amazon's New EC2 M7a AMD EPYC "Genoa" Instances Deliver Leading Performance In The AWS Cloud

Posted on by

While back in November was when AWS originally announced new EC2 instances powered by 4th Gen AMD EPYC “Genoa” processors, only this week did they bring their M7a general purpose instances to a general availability state where anyone can access them. Being very impressed with 4th Gen EPYC bare metal as well as with Azure’s HPC cloud, I fired up some benchmarks of the new Genoa-powered EC2 M7a instance compared to the new M7i instances powered by Intel Xeon Scalable “Sapphire Rapids” as well as showing how the competition is to Amazon’s in-house Graviton ARM-based server processors.

Initial AVX10.1 Support Merged Into The GCC Compiler

Posted on by

It was less than one month ago that Intel announced AVX10 as the successor to AVX-512. In that time Intel engineers have begun posting AVX10.1 enablement patches for GCC as well as beginning AVX10 discussions for the LLVM compiler stack. Overnight already the initial AVX10.1 enablement code has been merged into the GNU Compiler Collection…

StarFive VisionFive 2 Quad-Core RISC-V Performance Benchmarks

Posted on by

SiFive’s HiFive Unmatched development board was interesting when it began shipping in 2021 with 16GB of RAM and four U74-MC RISC-V cores along with one S7 core. But pricing was rather steep at $665 USD. Fast forward two years, the StarFive VisionFive 2 has begun to enjoy wide availability and for $100+ this RISC-V development board features a quad-core RISC-V processor via the StarFive JH7110 SoC with integrated GPU, up to 8GB of RAM, HDMI 2.0 output, dual Gigabit Ethernet, dual USB 3.0 ports, and more for around $100 USD. Here are some benchmarks of this most interesting RISC-V single board computer in the ~$100 space to be released yet.
