@PaulAlcorn , as far as I can tell, this article doesn't actually seem to link to the phoronix article, which is here:

​

These impressive gains might also extend to Intel's Xeon 6 'Granite Rapids' family of Xeon CPUs as well, though that remains to be confirmed.

Granite Rapids & Sierra Forest might see performance gains, but they would be mostly for different reasons. The AMD P-State driver definitely won't work on Xeons, which is the only factor cited here.

The Phoronix article also mentions:

"upgrading from Python 3.12 to Python 3.13, a newer OpenJDK 21 revision, and many other software updates that landed over the past six months."

Unfortunately, it seems Ubuntu 25.04 will use the 6.14 kernel. That means it won't have the patches to use the AMD-specific INVLPGB instruction, which invalidates TLB entries on other cores.

At least that means AMD still has gas left in the tank, although Intel might also have some untapped potential left in Granite Rapids.
