Phoronix: Intel Xeon Platinum 8380 Performance Is Looking Great For Linux 6.0

Not only is the AMD EPYC performance looking real good for Linux 6.0, but many of the scheduler changes and common kernel improvements also carry over well for Intel's Xeon Platinum 8380 "Ice Lake" server processors too. For your viewing pleasure this weekend are some initial benchmarks looking at Linux 5.19 stable compared to Linux 6.0 Git as we approach the end of the merge window...

Stay tuned for more benchmarks and kernel coverage over the coming weeks on Phoronix.

Amazing results. I wonder if the results will be noticeably better with performance governor? Thanks for the benchmarks btw.

Those are impressive improvements!

What's the "core reason" for these fairly substantial improvements for both Intel & AMD ?

Ha just wait till the next mitigation patch hits in.

Look on it from the bright side. Most of the problems come from out-of-order execution and speculation. So at most, we'll degrade to the performance of an Atom core (which should be an in-order design). On the other hand, if we are able to shuffle evermore I/O from left to right, that should benefit all CPUs, in-order designs included.
