They seem to be the best "communicators" on the market. With 1TB DDR5 and PCIe 5.0 support, a POWER10 will be the fastest "glue" between DDR5 and GPUs.
Which is pretty much how it works in the Summit supercomputer (POWER9).
--------
From a CPU-perspective, its going to be more costly than a Xeon or EPYC and not as fast at crunching numbers. But POWER9 (and I expect POWER10) usually had the best L3 cache and RAM performance.
The 1TB/sec OpenCAPI link to FPGAs or GPUs continues that tradition. That's an absurdly huge communication path between CPUs and/or GPUs or whatever else is on the motherboard.
