HOW TO CHOOSE
GB300 vs B200
The B200 is the mainstream Blackwell; GB300 adds memory and FP4 throughput for reasoning-class models. For most training the B200 is the practical part.
Workload fit
B200: frontier pre-training, fp4 inference, large moe training. GB300: frontier training, reasoning-model serving, anything small.
