Back in October following the launch of the EPYC 9005 "Turin" processors I ran an AVX-512 performance comparison for the EPYC 9755 with 512-bit data path vs. 256-bit data path vs. AVX-512 disabled. That was interesting for showing the benefits of Zen 5's full 512-bit data path support compared to the "double pumped" approach with Zen 4 or optionally used via a BIOS option on Zen 5. AVX-512 continues to prove to be very performant and power efficient with AMD Zen 5 processors unlike with the early generations of AVX-512 on Intel processors. Here is a fresh look at the AVX-512 performance on a Supermicro server with an AMD EPYC 9655 processor.

Earlier this month the Raspberry Pi 5 16GB was announced for finally pushing the Raspberry Pi single board computers beyond an 8GB limit for RAM. This opens up the Raspberry Pi 5 to new use-cases, more multi-tasking, and other applications where 8GB of RAM / 2GB per core was a bottleneck. In my tests thus far of the Raspberry Pi 5 16GB it's been working out well and helping the performance of some workloads by reducing the memory pressure / swapping.
