01 Side by side

What is the difference between the L40S and the A40?

Every figure is the one we rent against, taken from the same catalogue the dashboard prices from. Per-GPU-hour is the flat monthly price divided by 720 hours; you are never billed by the hour.

02 Verdict

Which should you rent?

Both cards carry 48 GB, so capacity is not what decides this one. The L40S supports FP8 and the A40 does not, which roughly halves the memory a quantised model needs and is the largest practical difference between the two. Bandwidth is 864 GB/s against 696 GB/s, and for single-stream token generation it is bandwidth that sets the speed, not the FLOPS figure on the spec sheet. The L40S costs 117% more per month, $520 against $240, or $0.72 against $0.33 per GPU-hour.

04 Questions

L40S against A40

Is the L40S better than the A40?

For anything memory-bound the L40S wins: 48 GB at 864 GB/s against 48 GB at 696 GB/s. For work that already fits in 48 GB the A40 is the better buy, because it costs $240 a month against $520 and the job finishes either way.

What is the price difference between the L40S and the A40?

At GPU Rent Hub the L40S is $520 a month and the A40 is $240, a gap of $280. Weekly terms are $148 and $68. Both prices are flat and include power, cooling, a public IPv4 and 20 TB of outbound traffic.

How much VRAM does the L40S have compared to the A40?

The L40S has 48 GB of GDDR6 ECC and the A40 has 48 GB of GDDR6 ECC. 48 GB with FP8 support and RT cores, the best inference card per dollar in our fleet.

Can I rent either card without KYC?

Yes. Both are rented on the same terms: an account is a username and a password, payment is Bitcoin, Ethereum, USDT, USDC, Monero, Solana or Litecoin, and no identity document is requested or stored at any point.

Which one is available today?

Stock moves. As of 2026-09-01 there were 74 L40S and 37 A40 cards free across DFW-1, IAD-1 and PDX-1. The per-region table above comes from the same inventory the dashboard deploys against.

Can I put several L40S cards in one machine?

Yes. Multi-GPU configurations sit on a single node with PCIe Gen4 peer-to-peer between the cards, and ordering two, four or eight takes 5%, 8% or 10% off the per-card price.
