As I wrote about last week within the Supermicro H13SSL-N EPYC Turin motherboard review, one of the factors leading me to purchasing that EPYC 9005 series motherboard was that this board offered support for full 12 channel DDR5-6000 memory performance compared to some of the other lower-cost Socket SP5 motherboards offering just 8 memory channels. For those wanting to quantify the performance difference between eight and twelve memory channels with AMD EPYC 9005 "Turin" processors, here are some benchmarks for showing the workloads that can really benefit from all 12 memory channels and other workloads where eight memory channels can be largely sufficient if looking to minimize costs.

Merged last year for Linux 6.6 was multi-grain(ed) timestamps to address the current coarse-grained timestamps when updating creation time and modification time that a lot of I/O activity can happen in the once-per-jiffy timestamp. Just a few weeks in the Linux 6.6 kernel, multi-grain timestamps were removed due to bugs. The multigrain code went back to be reworked and now just over one year later the code has been re-merged into the mainline Linux kernel...

Over the past year we have seen Canonical engineers focus more on optimizing the performance potential of Ubuntu Linux. With Ubuntu 25.04 they are now using the -O3 compiler optimization level by default and there has been other efforts like better performance tooling on Ubuntu and frame pointers by default.

At the beginning of November I wrote about AMD Linux engineers posting Linux patches enabling a new "ERAPS" feature for Zen 5. ERAPS wasn't talked about by AMD at the Zen 5 launches of the Ryzen 9000 / Ryzen AI 300 series or with the more recent EPYC 9005 "Turin" launch but when enabled, the Enhanced Return Address Prediction Security feature can help deliver some additional gains on new AMD Zen 5 systems by allowing some existing software security mitigations to be avoided. Here are some preliminary comparison benchmarks showing the benefit in affected workloads for using ERAPS on Linux with AMD Zen 5.
