Last week Intel began shipping their 13th Gen Core "Raptor Lake" processors. As noted in that launch-day article last week, unfortunately I wasn't able to deliver my usual Linux performance review in time due to hitting some DDR5 issues with my test platform, but those have now been resolved with a new Z790 motherboard. So as the first of my Raptor Lake Linux benchmarks, here is a look at how the top-end Core i9 13900K performs against the AMD Ryzen 7000 series on Ubuntu Linux along with the older Intel/AMD processors.

Needless to say, there also wasn't any progress on the re-clocking front for getting the GTX 900 series and later running in a performant manner on this open-source driver. But the Nouveau developers at Red Hat haven't simply been idling but rather have been working on the NVIDIA GPU System Processor (GSP) support for improving the RTX 20 "Turing" support and newer...
