H100 vs RTX 3060: Specs, VRAM & Price
Short answer: choose the H100 when 80 GB of VRAM is the gating requirement. Choose the RTX 3060 when 12 GB is enough for the workload and the lower hourly rate points that way.
The H100 has 80 GB of VRAM; the RTX 3060 has 12 GB.
You can rent both by the hour, no purchase required. H100 from $2.19/GPU/hr; RTX 3060 from $0.110/GPU/hr. The RTX 3060 is 95% cheaper at the entry rate.
H100
Good for training and serving frontier-scale LLMs
RTX 3060

H100 vs RTX 3060: common questions
Is the H100 or the RTX 3060 better for AI?
Short answer: choose the H100 when 80 GB of VRAM is the gating requirement. Choose the RTX 3060 when 12 GB is enough for the workload and the lower hourly rate points that way.
Is the H100 or the RTX 3060 cheaper to rent?
On Aquanode's live marketplace the H100 starts at $2.19/GPU/hr (median $4.09/GPU/hr) and the RTX 3060 starts at $0.110/GPU/hr (median $0.231/GPU/hr). The RTX 3060 is the cheaper of the two at the entry rate, by 95%.
What is the difference between the H100 and the RTX 3060?
The H100 has 80 GB of VRAM against the RTX 3060's 12 GB; the H100 is a Hopper part and the RTX 3060 is Ampere (compute capability 9.0 vs 8.6); only the H100 supports FP8 compute. On price, the H100 lists from $2.19/GPU/hr and the RTX 3060 from $0.110/GPU/hr.
How widely available are the H100 and the RTX 3060?
The H100 is listed in 8 regions and the RTX 3060 in 1 region right now.
How much does 1,000 GPU-hours cost on the H100 vs the RTX 3060?
At the lowest rates listed today, 1,000 GPU-hours costs $2,189 on the H100 and $110 on the RTX 3060, a difference of $2,079 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the H100 have compared to the RTX 3060?
The H100 has 80 GB of VRAM; the RTX 3060 has 12 GB.
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 H100 page and RTX 3060 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.
