    Haha, well, I recently discovered a Bavarian-focused butcher shop / store in Wisconsin that sells various Bavarian products and mails them... So I was ordering some things that I hadn't had in years, to much enjoyment - mostly some good meats. But they also happened to sell Paulaner Spezi... Spezi in America is rare and I haven't had any in ~8 years.

    Anyways, that box happened to arrive this past week and I had the cans sitting in the server room. So when it came time to taking some quick pictures for the article and seeing the Paualaner Spezi can orange color was close to the Ryzen coloring, I decided to toss it in the background to help prop up the CPUs.

    And, yes, the Spezi was tasty for not having it in many years.

      8 years certainly is a long time - at least you got the good stuff, Paulaner Spezi is way better than the "original" Spezi. By the way - mixing Coke and Fanta orange 50/50 works good as well as a replacement - though I think Coke tastes a little different in the US, so it might be a bit strange.

      Prost!

        Did some testing on my own on a dual AMD EPYC 7742 system. In most benchmarks there was no benefit of 5.11 or newer over 5.8.

        It seems that benchmarks in the article were somewhat cherry-picked. When looking at openbenchmarking.com most of these tests (especially the video encoding test) clearly favour lower core count, but high frequency CPUs. This is also the case for https://openbenchmarking.org/test/pts/build-godot-1.0.0 Here a single EPYC 7763 is faster than dual 7763. Also a dual 7443 (24-core) is faster than a dual 7763 (64-core).

        So in conclusion, the 5-6% improvement with 5.11 seems to be restricted to lower core count, higher frequency CPUs?
