    The article investigates avx 512 performance, it doesn't compare apples to oranges. But the perf per watt is core count agnostic, and intel is getting decimated there.

    Of course those are older gen chips as well, I suspect 12 and 13 gen will to a tad better.

    libxsmm with MNK=64 is a bandwidth limited operation and therefore not well suited for this comparison. You need a much larger matrix size to get the arithmetic intensity up high enough to make it compute bound. Only then will you see any impact from avx-512. I also notice in the first libxsmm plot that it was compiled with march=core-avx2!?

    My next thought was: "wow that Tiger Lake laptop is really smoking the Ice Lake". But, then I noticed the difference in power consumption and it seemed to explain a lot of that. In fact, the Tiger Lake laptop's power consumption went up by even more than its performance, which is why it's consistently worse than Ice Lake on the perf/W graphs.

    Finally, looking at power consumption, it's pretty impressive to see the 7840 is much closer to Ice Lake than Tiger Lake. On all the perf/W metrics, the new Ryzen really smokes them both.

    Amd beating intel at its own game in avx 512 and smt.

    Meanwhile, intel mocked amd's glue (which captured billions worth of market), then went on to pimp their own super-glue, then evidently super-glued their fingers together.

    Phoronix: AMD Ryzen 7040 Series Shows Great AVX-512 Performance For Laptops / Mobile / Edge

    Similar to what I have shown with the Ryzen 9 7950X AVX-512 desktop performance and AMD EPYC 9004 series AVX-512 server performance, the new Ryzen 7040 series mobile processors are exhibiting great AVX-512 performance for laptops. In today's article is a look at the performance impact when toggling AVX-512 capabilities for a Ryzen 7 7840U "Phoenix" SoC compared to toggling AVX-512 with prior Intel Tiger Lake and Ice Lake laptops that offer AVX-512.
