With the recent release of the GCC 9 stable compiler there is the initial "AMD GCN" GPU target/back-end merged. However, for this GNU Compiler Collection release the AMD GCN target isn't all that useful but continued work on it gives us hope of seeing it in good shape for next year's GCC 10 release...

It's been three months now since the AMD Radeon VII 7nm "Vega 20" graphics card was released and while we hopefully won't be waiting much longer for Navi to make its debut, for the time being this is the latest and great AMD Radeon consumer graphics card -- priced at around $700 USD. Here are some fresh benchmarks of the Radeon VII on Linux and compared to various high-end NVIDIA graphics cards while all testing happened from Ubuntu 19.04.

Since the release of Red Hat Enterprise Linux 8.0 at the start of May we've been running various benchmarks of this latest enterprise Linux platform. Our tests to date have been with Intel Xeon hardware where it's been performing well and a nice speed-up over RHEL 7 with modern Xeon Scalable CPUs. Similarly, AMD EPYC is also much faster with RHEL 8.0 thanks to the much newer Linux kernel, compiler, and other software updates.

Following the recent desktop CPU benchmarks and server CPU benchmarks following the MDS/ZombieLoad mitigations coming to light and looking at the overall performance cost to mitigating these current CPU vulnerabilities, there was some speculation by some in the community that the older dual-core CPUs with Hyper Threading would be particularly hard hit. Here are some benchmarks of a Lenovo ThinkPad with Core i7 Broadwell CPU looking at those mitigation costs...

The past few days I've begun exploring the performance implications of the new Microarchitectural Data Sampling "MDS" vulnerabilities now known more commonly as Zombieload. As I shared in some initial results, there is a real performance hit to these mitigations. In this article are more MDS/Zombieload mitigation benchmarks on multiple systems as well as comparing the overall performance impact of the Meltdown/Spectre/Foreshadow/Zombieload mitigations on various Intel CPUs and also AMD CPUs where relevant.
