Yet another AMD performance evaluation where the author is comparing against Intel CPUs from years ago. I get that that author might have only had access to these older Intel chips, but why go through the process of doing a lengthy comparison that really isn’t worthwhile?

Intel's later mobile processors don't have AVX-512, so this comparison is fair.

In addition to the linked articles from the start of this article (including Milan performance), they've previously compared Ice Lake vs Sapphire Rapids vs Genoa (https://www.phoronix.com/review/intel-sapphirerapids-avx512)

Newer Intel CPUs do not support AVX512. Tiger Lake is the most recent laptop CPU that does.

Didn't Intel kill AVX512 support on their 12th gen CPUs?

Intel removed AVX512 from their recent consumer chips, no?

Yes, but wouldn’t you have found this review more valuable if the comparison was made with a recently available Intel CPU that supported AVX-512 versus one from 2019?

Michael buys all these machines with his own money. You can buy him one, snark semi intended.

Yep sadly most laptop vendors don't care much about Linux... Or the Linux laptop vendors and others that do offer review samples, want them back in 30 days. So really doesn't work for long-term comparisons like this... But as mentioned by other commenters, the older Ice Lake and Tigerlake were explicitly used because they have AVX-512 support. For those just wanting to see newer AMD vs. newer Intel, that has already been covered in a separate article but this article here is specifically around "AVX-512".

Tigerlake is the most recent Intel laptop CPUs to officially support AVX-512... Thus can't do an Intel AVX-512 on/off comparison with any newer Intel laptop.

If you just want to see how the new AMD 7840U compares to a recent Intel Alder Lake, that's already been covered separately in: https://www.phoronix.com/review/amd-ryzen7-7840u
