A100 PCIe 80GB vs B200 (HGX, per GPU): specs and rental cost comparison
Direct answer
A100 PCIe 80GB vs B200 (HGX, per GPU): A100 PCIe 80GB is cheaper on the lowest tracked rental row at $1.39 per GPU-hour, versus $5.89 for B200 (HGX, per GPU). That makes B200 (HGX, per GPU) about 324% more expensive per GPU-hour on the cheapest rows in the ByteCosts GPU catalog. A100 PCIe 80GB has 80 GB VRAM and B200 (HGX, per GPU) has 180 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.
