    Phoronix: Intel i9-12900K Alder Lake Linux Performance In Different P/E Core Configurations

    One of the much requested Linux benchmarks since the debut of Intel Alder Lake last month has been for seeing the Core i9 12900K in different core configurations with its mix of P and E cores. Now that the Linux kernel activity has begun settling down around Alder Lake, here are those benchmarks for reference purposes with toggling Hyper Threading and different P and E core counts enabled.

    Wow, what a mess for a CPU meant to be an all-purpose design. Not what I had expected.

          Um, what did you expect? I see an impressive uArch which has the best in the world x86 single- and multi-threaded performance (in terms of performance per core). The temps are a bit high but that can be easily fixed by setting PL1/PL2 limits. A sweet spot for 12900K is around 170-190W.

            It would have been infinitely valuable if there was a Ryzen 9 5900X in each of those tests to compare with

            Interesting to see the mess the E-cores are in games, something that hardware Unboxed tried to show unsuccessfully

              Another one with "the mess". Are you sure you're using the right word here? HW Unboxed has actually praised Alder Lake and put it above Ryzens in their "Best 2021 CPUs":

                Oh, nvidia fanboy chose another company for his fetish. Maybe because of DLSS blurry failure that he promoted as a miracle, the best in the world and so on.. It seems birdie is just AMD hater.

                  I did not know we had the writer of UserBenchmark here, what a honor

                    Michael you say it gives the option to enable AVX 512 but you dont specify if you did or not, could you clarify?
