Phoronix recently benchmarked AMD's most sophisticated Ryzen mobile architecture, the 7040 mobile series, in AVX-512 workloads to see how performant it is compared to Intel's last two generations of AVX-512-supported CPUs in the mobile space. Turns out, AMD's Phoenix series CPUs are incredibly effective AVX-512 chips, easily beating out the competition in power efficiency and performance.
The CPUs Phoronix tested included a Ryzen 7 7840U, as well as Intel's older i7-1165G7, and i7-1065G7 — which were the last mobile CPUs to support AVX-512. The AMD chip blew past the older Intel CPUs outperforming the 1165G7 by 46% and outperformed the older 1065G7 by a whopping 63%. The Ryzen 7 chip also saw the highest performance gain when enabling AVX-512, with a 54% performance margin when enabling or disabling AVX-512. The Intel chips weren't even close, with a performance margin of 35%.
