A100 vs H200: Specs, VRAM & Price
Short answer: choose the H200 when 141 GB of VRAM is the gating requirement. Choose the A100 when 80 GB is enough for the workload and the lower hourly rate points that way.
The A100 has 80 GB of VRAM; the H200 has 141 GB.
You can rent both by the hour, no purchase required. A100 from $1.10/GPU/hr; H200 from $3.98/GPU/hr. The A100 is 72% cheaper at the entry rate.
A100
Good for training and inference on models that don't need FP8 kernels
H200
Good for training and serving frontier-scale LLMs

A100 vs H200: common questions
Is the A100 or the H200 better for AI?
Short answer: choose the H200 when 141 GB of VRAM is the gating requirement. Choose the A100 when 80 GB is enough for the workload and the lower hourly rate points that way.
Is the A100 or the H200 cheaper to rent?
On Aquanode's live marketplace the A100 starts at $1.10/GPU/hr (median $1.72/GPU/hr) and the H200 starts at $3.98/GPU/hr (median $5.43/GPU/hr). The A100 is the cheaper of the two at the entry rate, by 72%.
What is the difference between the A100 and the H200?
The A100 has 80 GB of VRAM against the H200's 141 GB; the A100 is an Ampere part and the H200 is Hopper (compute capability 8.0 vs 9.0); only the H200 supports FP8 compute. On price, the A100 lists from $1.10/GPU/hr and the H200 from $3.98/GPU/hr.
How widely available are the A100 and the H200?
The A100 is listed in 5 regions and the H200 in 4 regions right now.
How much does 1,000 GPU-hours cost on the A100 vs the H200?
At the lowest rates listed today, 1,000 GPU-hours costs $1,102 on the A100 and $3,982 on the H200, a difference of $2,880 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the A100 have compared to the H200?
The A100 has 80 GB of VRAM; the H200 has 141 GB.
Does the A100 or the H200 support NVLink?
Yes, both support a multi-GPU interconnect: the A100 has NVLink 3, 600 GB/s and the H200 has NVLink 4, 900 GB/s bidirectional.
How this comparison is calculated
Every price is normalized to a per-GPU hourly rate using the same pipeline as every other pricing surface on Aquanode, and only the cheapest qualifying offer per provider is shown. A dash means that provider does not currently list that GPU.
Architecture, compute capability and supported precisions come from each vendor's published datasheet for that generation, not from the marketplace feed. This page regenerates at most once per hour.
Memory bandwidth, tensor TFLOPS, NVLink/interconnect and max board power are the same verified-from-datasheet figures shown on each model's own A100 page and H200 page, which link the primary vendor source for that model. A dash here means Aquanode hasn't verified that figure from a primary source yet, never a guess.
