L40S vs RTX PRO 5000: Specs, VRAM & Price
Short answer: choose the RTX PRO 5000 when you want the lower hourly rate and the specs are otherwise a wash. Choose the L40S when L40S pricing or availability works better where you're deploying.
Both the L40S and the RTX PRO 5000 ship with 48 GB of VRAM.
You can rent both by the hour, no purchase required. L40S from $1.03/GPU/hr; RTX PRO 5000 from $0.918/GPU/hr. The RTX PRO 5000 is 11% cheaper at the entry rate.

L40S vs RTX PRO 5000: common questions
Is the L40S or the RTX PRO 5000 better for AI?
Short answer: choose the RTX PRO 5000 when you want the lower hourly rate and the specs are otherwise a wash. Choose the L40S when L40S pricing or availability works better where you're deploying.
Is the L40S or the RTX PRO 5000 cheaper to rent?
On Aquanode's live marketplace the L40S starts at $1.03/GPU/hr (median $2.47/GPU/hr) and the RTX PRO 5000 starts at $0.918/GPU/hr (median $0.999/GPU/hr). The RTX PRO 5000 is the cheaper of the two at the entry rate, by 11%.
What is the difference between the L40S and the RTX PRO 5000?
Both cards report 48 GB of VRAM; the L40S is an Ada Lovelace part and the RTX PRO 5000 is Blackwell (compute capability 8.9 vs 12.0); both run BF16, FP8, INT4 workloads in hardware. On price, the L40S lists from $1.03/GPU/hr and the RTX PRO 5000 from $0.918/GPU/hr.
How widely available are the L40S and the RTX PRO 5000?
The L40S is listed in 4 regions and the RTX PRO 5000 in 1 region right now.
How much does 1,000 GPU-hours cost on the L40S vs the RTX PRO 5000?
At the lowest rates listed today, 1,000 GPU-hours costs $1,028 on the L40S and $918 on the RTX PRO 5000, a difference of $110 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the L40S have compared to the RTX PRO 5000?
Both the L40S and the RTX PRO 5000 ship with 48 GB of VRAM.
Does the L40S or the RTX PRO 5000 support NVLink?

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 L40S page and RTX PRO 5000 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.
