AVX-512's Enormous Advantage For AMD EPYC 4005 Series Performance
First up was the NAMD 3.0 molecular dynamics software package, which is best suited for EPYC 9005 class server processors but for EPYC 4005 does good for exhibiting the impact of AVX-512. Even with the EPYC 4345P and disabling AVX-512, at the same core/thread count as the Xeon 6369P it was still 28% faster than the Intel Xeon 6369P flagship SKU of the Xeon 6300 series. In this exceptional case thanks to AVX-512 is more than 2x the performance than when having it disabled.
AVX-512 with the EPYC 4005 series can be of enormous benefit to Advanced Vector Extensions 512 capable workloads, as shown in tests as well with the EPYC 9004/9005 series and AMD Ryzen 7000/8000/9000 series too.
As shown in other HPC software packages able to make use of AVX-512, there can be huge advantages to leveraging AVX-512 on AMD Zen 5 processors. Even without AVX-512 being enabled, the EPYC 4345P 8-core processor was still surpassing the Xeon 6369P competition while in its standard load-out configuration easily whoops that Xeon E-2400 series successor while the EPYC 4585PX performance is in a whole separate ballpark.
