"According to the Grace Blackwell's datasheet- Up to 480 gigabytes (GB) of LPDDR5X memory with up to 512GB/s of memory bandwidth. It also says it comes in a 120 gb config that does have the full fat 512 GB/s."

"up to 512GB/s of memory bandwidth per Grace CPU"

- moffkalast 2y agoYep I think that's it. So it's referencing the GB200, it could have absolutely nothing in common with this low power version.
- sliken 2y agoKeep 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.
