Yeah exactly. Shader model 121 is different to SM 120 (consumer Blackwell) and is different again to data centre Blackwell SM100.
The promise of this chip was “write your code locally, then deploy to the same architecture in the data centre!”
Which is nonsense, because the GB10 is better described as “Hopper with Blackwell characteristics” IMO.
Still great hardware, especially for the price and learning. But we are only just starting to get the kernels written to take advantage of it, and mma.sync is sad compared to tcgen05
