01 Side by side

What is the difference between the L40S and the RTX 4090?

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?

The L40S carries 24 GB more memory, which is the only thing that decides whether a model loads at all. Bandwidth is 864 GB/s against 1.01 TB/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 33% more per month, $520 against $390, or $0.72 against $0.54 per GPU-hour.

04 Questions

L40S against RTX 4090

Is the L40S better than the RTX 4090?

For anything memory-bound the L40S wins: 48 GB at 864 GB/s against 24 GB at 1.01 TB/s. For work that already fits in 24 GB the RTX 4090 is the better buy, because it costs $390 a month against $520 and the job finishes either way.

What is the price difference between the L40S and the RTX 4090?

At GPU Rent Hub the L40S is $520 a month and the RTX 4090 is $390, a gap of $130. Weekly terms are $148 and $110. 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 RTX 4090?

The L40S has 48 GB of GDDR6 ECC and the RTX 4090 has 24 GB of GDDR6X. 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 265 RTX 4090 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.
