Where did you get those numbers from?

DGX Spark has a maximum of 273 GB/s bandwidth in ideal scenarios (hard to reach)

That puts it between an M5 (153) and M5 Pro (307)

The 900 GB/s is from the NVLink-C2C interconnect, if you were wondering about that. They quote "up to 900 GB/s of bidirectional bandwidth between GPU and CPU".

Mind you thats not to/from memory, which indeed only has 273 GB/s.

Ah I see. But the only C2C equivalent on the Apple side is the UltraFusion which is 2.5TB/s if I recall correctly.
