What's the cheapest 80 GB GPU to rent?

The cheapest 80 GB-class GPU today is the NVIDIA A100 80GB PCIe at $1.40/GPU-hr median across tracked providers.

• 80 GB is the workhorse tier: it fits 70B-class models at 8-bit and most fine-tuning setups.
• Per unit of compute the ranking can flip: the NVIDIA A100 80GB PCIe costs $4.47/PFLOP-hr vs the H100 SXM's $3.91 (BF16, dense).
• Older generations get cheaper per hour but not always cheaper per FLOP — check each SKU page's cost-of-compute line.
