What is their performance?
Re: Talos II
#13Looks interesting, I didn't even know that you still could buy PowerPC she. Anyone know of pros and cons?
POWER was historically the architecture for "I don't care about efficiency, I just want a fast machine!". This hasn't really changed. For some applications they are still substantially faster than any x86 system, but they're almost always far less power efficient. That's why they're not widely adopted in data centres.
That may be a con for a data center or battery-powered device, but not so much for a workstation.

POWER CPU cores typically have N-way hardware threads, like 8 or so usually. So you're probably looking at something closer to 32 hardware threads per socket. The original Talos offered 12 core variants (96 per socket!) but had no dual socket config. Also, the memory bandwidth and cache on these things is insane even compared to top of the line, absolute highest-end Xeons, so there are many factors besides raw CPU count.
I don't know if those numbers are upped with a POWER9 CPUs (I wasn't even sure if POWER9 was really shipping yet?)

#17How would this compare to a ThreadRipper/EPYC system? Any advantages in favor of Talos?
Huge memory BW, CAPI2, 8-way SMT, 120MB L3 cache, L4 cache, compression and crypto coprocessor, etc...

#18I wish I could afford one.

#19Earlier quoted context omitted.
Do you not consider the freedom aspects (e.g. sources to the secure boot implementation, no x86, etc) as advantages in favour of Talos?
That's definitely nice! Any other advantages?
The Power9 should be more performant than EPYC/ThreadRipper and CAPI gives you higher memory bandwidth to a GPU.
