GPU MODELS / ALTERNATIVES TO B300
Alternatives to the B300
The B300 (Blackwell Ultra) is NVIDIA's inference-first Blackwell refresh: 288 GB of HBM3e - half again the B200's memory - with FP4 throughput tuned for reasoning models that generate long chains of thought. It targets the largest serving deployments; training fleets stay on B200-class parts.
People usually compare the B300 against B200. Prices below are live on-demand published rates from the panel.

B200
Same bandwidth, 50% more memory, more FP4. Serving fleets with huge models take the B300; everyone else compares live rates.
B300 ALTERNATIVES - FAQ
What is the best alternative to the B300?
It depends on the workload. 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. Live rates for each are in the table above.
Why look for B300 alternatives?
Training fleets - it is an inference-first part.
How much does the B300 cost compared to its alternatives?
Each alternative's current cheapest published rate is listed in the table above; figures recompute hourly from provider-published prices.
