B300 vs H100 NVL 94GB: specs and rental cost comparison
B300 vs H100 NVL 94GB: H100 NVL 94GB is cheaper on the lowest tracked rental row at $0.36 per GPU-hour, versus $6.60 for B300. That makes B300 about 1727% more expensive per GPU-hour on the cheapest rows in the ByteCosts GPU catalog. B300 has 288 GB VRAM and H100 NVL 94GB has 94 GB VRAM. The tables compare source-backed specs and value metrics only where both GPUs have a real spec field and a tracked rental rate. Rental prices are list rates per GPU-hour, before committed-use discounts, capacity limits, or region constraints.
