    If we even could see a dual AMD Epyc system, finally. - Bridgman?

      Well that explains why Intel tried to prevent people doing benchmarks of their latest microcode... that's a much bigger drop in performance than AMD suffers.

        It doesn't, the microcode update provides an optimization for virtual machines, so it makes things a little faster. They probably forgot to update the license after issuing a pre-release version.

              I hope distros put an easy switch somewhere to disable these mitigations for those of us seeking performance.

                hahahaha 10-20% drop in performance on Intel, it's over, Intel is bankrupt and finished

                  It would be great if you had a --relative flag or something for the graphs because a chart that starts in the middle and moves to the left and right from the center.

                    So wait you're saying this is actually faster? And you don't see the problem here?

                      Skylake takes the biggest hit so why not a comparison with common and recent processors?: i7-8700K vs R7 2700X?
