On the CPU-only side of things though, I hope 5 racks of Epyc 9965s (491,520 cores) will yield better than 10 PF/s, seeing how Wisteria/BDEC-01 (Odyssey), Crossroads, Shaheen III – CPU, and MareNostrum 5 GPP get from 22 to 40 PF/s of Rmax with 369K, 661K, 878K, and 726K cores, respectively (less than twice the 490K). Maybe the Zen 5c is not optimal for this use case and a “plain vanilla, fatter cached Zen 5, variant of the top bin Turin processor”, say the “Epyc 9755 that HPE has not chosen”, would indeed be better in this (possibly besting Archer2 on HPCG, with fewer cores …)!

It would be a pain in the neck, but it might make sense.

Iirc there have been many stories lately about compute being restrained because the feedtroughs are too slow.

I think they want a hearty soup, and perhaps we shall see one also being sold.
