Linux 4.14 Kernel Benchmarks With The Intel Core i9 7980XE

Following my Linux benchmarks of the newly-launched Core i9 7960X and Core i9 7980XE processors, here are benchmarks of the 18 core / 36 thread Extreme Edition processor when running on Linux 4.14.

Linux 4.14 has quite a few new features in the works from EXT4 scalability work, the PCID support for potential performance benefits with Intel CPUs, DRM driver improvements, and more. Out of curiosity I ran some early Linux 4.14 Git benchmarks on the Core i9 7980XE system.

Tests were compared to Linux 4.12 and 4.13 stable. Also a run with nopcid on Linux 4.14 for looking at whether the PCID code is making an impact on this system.

EXT4 writes are faster in some instances. Our EXT4 results on Linux 4.14 have been mixed but overall an improvement thanks to the scalability work that was merged.

Those using the AMDGPU DRM driver may see some performance improvements.

But on this high core count rig, not many of the CPU-bound tests saw much of a change with Linux 4.14.

Himeno is among the few tests looking to do slightly better with Linux 4.14.

Redis is looking to be a little bit faster.

More data over on while tests on more systems are forthcoming.
