Last week AMD published their Zen 3 support for GCC code compiler. That initial support, which has already been merged into GCC 11, is the initial support flipping on newly supported instructions but not yet offering any tuned scheduler model or other optimizations compared to the existing Zen 2 path. In any case, here is a look at the performance changes with building the open-source benchmarks under test with "znver3" compared to the prior Zen 2 and Zen 1 targets along with generic x86_64 and then also looking at the performance if catering the compiler targets for Intel's Skylake and Haswell processors.

It's been just over one month since AMD launched the Ryzen 5000 series as the first processors part of the Zen 3 family. The Linux performance continues to be terrific with the Ryzen 5600X / 5800X / 5900X / 5950X parts in our continued benchmarking...

Well here is a surprise for those that have long used CentOS as the community-supported rebuild of Red Hat Enterprise Linux... CentOS 8 will end in 2021 and moving forward CentOS 7 will remain supported until the end of its lifecycle but CentOS Stream will be the focus as the future upstream of RHEL...

After the Radeon RX 6800 series launched just under a month ago, the flagship AMD Radeon RX 6900 XT is launching today. This is currently the most powerful RDNA 2 graphics card and should work under Linux with the open-source driver stack but the card is likely to be scarcer than even the RX 6800 series...
