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

- MrBuddyCasino 3mo agoThe 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.
- dagmx 3mo agoAh I see. But the only C2C equivalent on the Apple side is the UltraFusion which is 2.5TB/s if I recall correctly.
- MrBuddyCasino 3mo agoYes its not an "Apple M killer" at all. Also, the available official performance numbers are partially overstated (1 Petaflop is only possible for sparse FP4 models, "in theory"). Perhaps a sobering rule of thumb: if it was actually useful, you couldn't buy them because someone would scoop them all up to shove them in a DC and make money with it.
