The NVIDIA H100 is still the most widely deployed data-center GPU for AI training and inference in 2026. This guide covers every spec variant, real cloud rental rates, the buy-vs-rent break-even math, and how the H100 stacks up against the A100 and H200 — so you can make a cost-justified decision fast.
The NVIDIA B200 (Blackwell) is the most capable cloud GPU you can rent right now — but prices vary by 4–7× across providers. This guide breaks down current per-hour B200 pricing, compares hyperscalers vs. specialist clouds, explains spot vs. reserved strategies, and helps you decide when the B200 premium actually pays off.
NVIDIA H100 cloud rental costs roughly $1.99/hr on RunPod, $2.49/hr on Lambda Labs, and about $1.87/hr on Vast.ai, dropping to ~$1.03/hr on spot (Spheron). Hyperscalers charge far more — up to ~$12/hr on Azure. The most striking fact about H100 pricing in 2026: the same GPU can cost nearly 14x more on one provider than … Read more
Renting a cloud GPU costs roughly $0.20–$0.50/hr for a consumer RTX 4090, $1.50–$3.60/hr for an NVIDIA H100 on specialized AI clouds (up to ~$14/hr on hyperscalers), and $2.25–$6/hr for a B200. Spot pricing cuts these 50–80% for interruptible workloads. Your actual cost depends on the GPU, the provider tier, and whether you use on-demand or … Read more
