recent phonics Benchmarked We used AMD’s most sophisticated Ryzen mobile architecture, the 7040 Mobile Series, with AVX-512 workloads to see how well it performed compared to the last two generations of Intel’s AVX-512 capable CPUs in the mobile space. confirm. We found AMD’s Phoenix series CPUs to be highly efficient AVX-512 chips, easily beating the competition in terms of power efficiency and performance.
The CPUs Phoronix tested included the 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 far outperformed the old Intel CPU, beating the 1165G7 by 46% and the old 1065G7 by a whopping 63%. The Ryzen 7 chips also saw the best performance boost with AVX-512 enabled, with a performance margin of 54% with and without AVX-512 enabled. It fell short of Intel chips with a 35% performance margin.
AMD’s performance boost with AVX-512 is impressive, especially considering Zen 4 (the CPU architecture used by the 7840U) was Team Red’s first architecture to adopt the new instruction set. Conversely, Intel has years of experience developing his AVX-512 capable architecture, but has been unable to extract the same performance margins as AMD. Intel also had to address other architectural oddities found in Rocket Lake and Alder Lake when it comes to AVX-512 performance and features that aren’t found in AMD’s Zen 4 architecture.
AVX-512 is a relatively new instruction set originally developed by Intel in the mid-2010s. This instruction set provides more efficient data processing compared to other AVX standards and can power highly complex computational workloads such as scientific simulation, 3D modeling, analytics, data compression, and deep learning.
This instruction set was first adopted in desktop consumer chips, beginning with HEDT processors in Intel’s Skylake-X CPU lineup in 2017. Since then, this instruction set has been introduced into desktop and mobile consumer his chips such as Rocket Lake, Tiger Lake and Ice Lake.
Unexpectedly, however, Intel dropped support for AVX-512 altogether upon Alder Lake’s launch, even though that architecture featured improved AVX-512 features over Rocket Lake. The problem was Intel’s inability to get his AVX-512 working in conjunction with his E-core, which doesn’t support his AVX-512 at all. Oddly enough, AVX-512 actually worked on P cores for a while, as long as I disabled the E cores from the BIOS.
Ironically, AMD was busy integrating AVX-512 into its Zen 4 CPU architecture when Alder Lake was discontinued, so 2022 could be the worst year for Intel to drop AVX-512 support on the consumer side. One of the years.
So not only will AMD’s Zen 4 mobile CPUs feature AVX-512 support, but they will also be the only player in the space until Intel decides to reintroduce AVX-512 in their consumer mobile chips in the future. I have. This will greatly improve the performance of AMD powered notebooks for users who can take advantage of AVX-512’s high speed processing capabilities.
