Along with Linux 6.6 delivering higher outcomes on AMD EPYC servers, Intel Xeon Max / Sapphire Rapids can also be selecting up some efficiency wins on this forthcoming model of the Linux kernel. Listed here are some comparability benchmarks wanting on the Intel Xeon Max 9480 2S efficiency between Linux 6.5 steady and the upcoming Linux 6.6 kernel.
This text provides a straight-forward take a look at how Linux 6.5 steady compares to a latest Linux 6.6 Git state for the efficiency variations when operating two Intel Xeon Max 9480 processors (Sapphire Rapids with HBM2e) in caching mode on a Supermicro X13DEM platform.
The entire {hardware} was saved the identical as all the time throughout testing and simply switching out the kernel model in use. For simple reproducibility the Linux kernel photos have been obtained by way of the Ubuntu Mainline Kernel PPA.
Total there are a variety of minor enhancements for the Intel Sapphire Rapids efficiency on Linux 6.6. This new kernel brings the EEVDF scheduler and different enhancements. The positive aspects tended to not be as vital although as on the AMD EPYC facet the place Linux 6.6 additionally has some new optimizations for benefiting chiplet CPUs and different AMD-focused enhancements. In any case Linux 6.6 is constant to look fairly good for each AMD and Intel platforms.
