Keep in mind the "full" grace is a completely different beast with Neoverse cores. This new GB10 uses different cores and might well have a different memory interface. I believe the "120 GB" config includes ECC overhead (which is inline on Nvidia GPUs) and Neoverse cores have various tweaks for larger configurations that are absent in the Cortex-x925. I'd be happy to be wrong, but I don't see anything from Nvidia that implies a 512 bit wide memory interface on the Nvidia Project DIgits.
