01 Side by side

What is the difference between the RTX 5090 and the L40S?

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 cheaper L40S carries 16 GB more memory, so on capacity alone it is the better card. Bandwidth is 1.79 TB/s against 864 GB/s, and for single-stream token generation it is bandwidth that sets the speed, not the FLOPS figure on the spec sheet. The RTX 5090 costs 4% more per month, $540 against $520, or $0.75 against $0.72 per GPU-hour.

04 Questions

RTX 5090 against L40S

Is the RTX 5090 better than the L40S?

For anything memory-bound the RTX 5090 wins: 32 GB at 1.79 TB/s against 48 GB at 864 GB/s. For work that already fits in 48 GB the L40S is the better buy, because it costs $520 a month against $540 and the job finishes either way.

What is the price difference between the RTX 5090 and the L40S?

At GPU Rent Hub the RTX 5090 is $540 a month and the L40S is $520, a gap of $20. Weekly terms are $155 and $148. Both prices are flat and include power, cooling, a public IPv4 and 20 TB of outbound traffic.

How much VRAM does the RTX 5090 have compared to the L40S?

The RTX 5090 has 32 GB of GDDR7 and the L40S has 48 GB of GDDR6 ECC. 32 GB of GDDR7 at 1.79 TB/s, faster memory than an A100 for a fifth of the price.

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 100 RTX 5090 and 74 L40S 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 RTX 5090 cards in one machine?

Yes. Multi-GPU configurations sit on a single node with PCIe Gen5 peer-to-peer between the cards, and ordering two, four or eight takes 5%, 8% or 10% off the per-card price.
