For NUMA aware software the NPS/SNC tuning can be an easy win for performance.
👁 Rodinia benchmark with settings of Test: OpenMP Streamcluster. Default - Disabled was the fastest.
But it's not a universal win so it really comes down to what workloads you're running most frequently to know whether it's a worthwhile adjustment on your HEDT/workstation.
The performance benefits though from this simple BIOS adjustment can be quite beneficial though for various real-world workloads like the computational fluid dynamics (CFD) performance with the OpenFOAM software.
For those using AMD Ryzen Threadripper 7000 series in production it's certainly a worthwhile consideration to make prior to deployment for evaluating the best Sub-NUMA Clustering / Nodes Per Socket configuration for your environment.
