L40 vs RTX 3070: Specs, VRAM & Price
Short answer: choose the L40 when 48 GB of VRAM is the gating requirement. Choose the RTX 3070 when 8 GB is enough for the workload and the lower hourly rate points that way.
The L40 has 48 GB of VRAM; the RTX 3070 has 8 GB.
You can rent both by the hour, no purchase required. L40 from $0.759/GPU/hr; RTX 3070 from $0.143/GPU/hr. The RTX 3070 is 81% cheaper at the entry rate.
L40

L40 vs RTX 3070: common questions
Is the L40 or the RTX 3070 better for AI?
Short answer: choose the L40 when 48 GB of VRAM is the gating requirement. Choose the RTX 3070 when 8 GB is enough for the workload and the lower hourly rate points that way.
Is the L40 or the RTX 3070 cheaper to rent?
On Aquanode's live marketplace the L40 starts at $0.759/GPU/hr (median $0.902/GPU/hr) and the RTX 3070 starts at $0.143/GPU/hr (median $0.143/GPU/hr). The RTX 3070 is the cheaper of the two at the entry rate, by 81%.
What is the difference between the L40 and the RTX 3070?
The L40 has 48 GB of VRAM against the RTX 3070's 8 GB; the L40 is an Ada Lovelace part and the RTX 3070 is Ampere (compute capability 8.9 vs 8.6); only the L40 supports FP8 compute. On price, the L40 lists from $0.759/GPU/hr and the RTX 3070 from $0.143/GPU/hr.
How widely available are the L40 and the RTX 3070?
The L40 is listed in 3 regions and the RTX 3070 in 1 region right now.
How much does 1,000 GPU-hours cost on the L40 vs the RTX 3070?
At the lowest rates listed today, 1,000 GPU-hours costs $759 on the L40 and $143 on the RTX 3070, a difference of $616 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the L40 have compared to the RTX 3070?
The L40 has 48 GB of VRAM; the RTX 3070 has 8 GB.
Does the L40 or the RTX 3070 support NVLink?
Neither the L40 nor the RTX 3070 has a dedicated GPU-to-GPU interconnect.
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 L40 page and RTX 3070 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.
