HOW TO CHOOSE
GB200 vs B200
The GB200 is the Grace-integrated, rack-scale form of B200-class silicon with NVLink 5 fabric. Same-generation compute, but bought as rack-scale slices versus standalone 8-GPU nodes. If you do not need the NVLink domain, B200 rows are the same chip class for less.
Workload fit
B200: frontier pre-training, fp4 inference, large moe training. GB200: frontier llm training, massive-scale inference, anything small.
B200 VS GB200 - FAQ
Which is cheaper to rent, B200 or GB200?
By today's published on-demand rates: B200 starts at $2.490/GPU/hr (median $6.25, 36 providers) and GB200 starts at $8.000/GPU/hr (median $16.00, 2 providers). The cheapest live listing is the B200 at SpotGPUs. Figures recompute from the panel on every refresh.
B200 or GB200 - which should I rent?
B200: The B200 is Blackwell's datacenter flagship: roughly 2.3x the H100's dense compute, a new FP4 precision that doubles effective inference throughput, 192 GB at 8 TB/s, and NVLink 5 at 1.8 TB/s. GB200: GB200 is not a card but a module - one Grace CPU plus two Blackwell GPUs - and the NVL72 rack built from 36 of them is the 2025-2026 frontier training system. The side-by-side spec table and live price rows above give the full picture.
