This is an huge deal : the 5700U is faster than the Mac M1 at the same wattage https://www.cpubenchmark.net/compare/Apple-M1-8-Core-3200-MHz-vs-AMD-Ryzen-7-5700

If you have embarrassingly parallel loads, sure. But: CPU Single Thread Rating Apple M1 - 3,778 AMD 5700U - 2,636 suggests that "is faster" is going to depend on your perspective. Most loads I care about are single threaded. The 5700U is 8% faster on a synthetic multi-core benchmark vs. 30% slower on a single core benchmark. I know which CPU I'd choose if I had a choice.

  We're lucky now to be in the ballpark.

  I also doubt the AMD chip got those results anywhere near the 15w TDP. I didn't find concrete numbers on the 5700U, though. I would take an AMD chip over the M1 in a desktop any day, but not in a laptop.

  Woah. Nice quote about "CPU Single Thread Rating". Can you share a source? I can understand why there is this real push to reverse engineer the M1 platform to get Linux running on it! The efficiency per watt is amazing.

  It is even worst considering 1. The Max boost clock of 5700U is 4.3Ghz. Compared to M1 at 3.2Ghz 2. The TDP of 5700 is Typical TDP, it doesn't actually take into account of boost. Not that it matters in a single thread performance comparison because it wont use 15W per single core, but still relevant info to keep in mind. On the other hand this is a Zen 2 on 7nm compared to M1 on 5nm. The Gap would be less if it was on Zen 3 and 5nm. But even then my guess it would something like 3000, still quite a bit to go to catch up with 3800.

Now imagine if AMD could also use 5nm like Apple. Chip shortage is hurting a lot.
