Here is a fresh look at the NVIDIA GeForce and AMD Radeon Linux graphics card performance as we start 2018. Testing was done using the latest Linux 4.15 Git kernel -- including the KPTI page table isolation support -- as well as using the newest Mesa 17.4-dev driver code for RadeonSI/RADV and on the NVIDIA side is their brand new 390.12 beta driver.

There's still a week and a half to go until the Linux 4.15.0 stable kernel release is expected and that rings in the Linux 4.16 merge window. On top of various Linux 4.16 changes already talked about, here's a look at some of the other kernel features/additions expected for this next release cycle...

Over the past week I have posted many KPTI and Retpoline benchmarks for showing the performance impact of these patches to combat the Spectre and Meltdown vulnerabilities. But with my testing so far I haven't done any showing the combined impact of KPTI+Retpoline on Ubuntu versus a completely unpatched system. Here are some of those results...

Yesterday Intel landed KPTI page table isolation and Retpoline support in their Clear Linux distribution. Given that one of the pillars of this Intel Open-Source Technology Center platform is on delivering optimal Linux performance, I was curious to see how its performance was impacted. Here are before/after benchmarks on seven different systems ranging from low-end Pentium hardware to Xeon servers.

While the Kernel Page Table Isolation (KPTI) patches were quick to land in the mainline Linux kernel for addressing the Meltdown CPU vulnerability, the "Retpoline" patches are still being worked on as the leading approach on the Linux side for dealing with the Spectre CPU vulnerability. The Retpoline patches are said to have little impact on performance, but here are our benchmarks of these kernel patches for seeing how they affect a variety of AMD and Intel systems.
