Hmm, the 128-core Ampere Altra CPU is already available, and in a case from System76. I wonder what else differentiates it.
If they're going to build CPUs I wish they had used Risc-V instead. They are using it somewhat already.

The CPU is integrated with two Rubin GPUs but each of the CPU cores has dedicated FP8 acceleration as well.

The Nvidia CPUs are designed for a very specific use case. They are designed for high performance with less concern about cost control.
The newer AmpereOne CPUs use DDR5 with the AmpereOne M supporting even higher memory bandwidth. Even then, I doubt the AmpereOne CPUs will match the performance of the Nvidia Rubin CPUs. But the Ampere processors are available for general use. I am guessing that Nvidia is only going to sell the complete rack system and only to high-volume customers.
