On: IBM Preps Power9 for AI and HPC Launch, Forges Big NUMA Iron

[sp332]

IBM only has 3 processors announced so far and they look pretty similar. https://en.wikipedia.org/wiki/POWER9#Variants Also the CPU page https://raptorcs.com/content/CP9M01/intro.html says "additional Sforza CPU options are planned" so... they're probably Sforza.

It seems they're all in the Sforza family. I'd like to see their bigger brothers, though this workstation seems quite impressive by itself.

The Zaius/Barreleye systems use the LaGrange chips instead; the quick breakdown I made for wikipedia was:

    Sforza —   50 mm × 50 mm,     4 DDR4, 48 PCIe Lanes, 1 XBus 4B
    Monza —    68.5 mm × 68.5 mm, 8 DDR4, 34 PCIe Lanes, 1 XBus 4B
    LaGrange — 68.5 mm × 68.5 mm, 8 DDR4, 42 PCIe Lanes, 2 XBus 4B

Though I have no idea what XBus is.
