AMD Ryzen 9 9900X3D Impact Of The 3D V-Cache Optimizer Linux Driver

Last month I posted benchmarks showing the performance when using the new 3D V-Cache Optimizer driver on Linux using the flagship Ryzen 9 9950X3D. This optimizer driver allows tuning the “amd_x3d_mode” for indicating your prefereoce for the CCD with the higher frequency or larger cache size. For some additional insight into the 3D V-Cache Optimizer driver performance impact on Linux, here are benchmarks looking at the difference while using the AMD Ryzen 9 9900X3D.

Linux 6.15 Further Improves AMD P-State Driver, Intel Dev Tackles A ~50% SPEC Regression

Linux power management and ACPI subsystems maintainer Rafael Wysocki last week sent out the assortment of ACPI/PM material for the new Linux 6.15 kernel cycle. The AMD P-State driver continues to be heavy with its code churn and there have been various other optimizations and code clean-ups. The CPUIdle Menu governor also received some performance tuning worth mentioning…
