RTX 5090 vs RTX 4090: specs, price and which to rent
GPU Rent Hub rents both cards as dedicated bare metal in three United States datacenters, paid in Bitcoin, Ethereum, USDT, USDC, Monero, Solana or Litecoin with no identity verification. The RTX 5090 is $540 a month and the RTX 4090 is $390 a month. Everything below is measured, not argued.
What is the difference between the RTX 5090 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.

Which should you rent?
The RTX 5090 carries 8 GB more memory, which is the only thing that decides whether a model loads at all. Bandwidth is 1.79 TB/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 RTX 5090 costs 38% more per month, $540 against $390, or $0.75 against $0.54 per GPU-hour.
Rent the RTX 5090 when
Fast single-card inference on 7B–32B models. 32 GB of GDDR7 at 1.79 TB/s, faster memory than an A100 for a fifth of the price.
$540/mo · $155/wk · specifications and stock
Rent the RTX 4090 when
ComfyUI, Stable Diffusion and video pipelines. The workhorse: 24 GB, 1 TB/s, and the largest stock in our fleet.
$390/mo · $110/wk · specifications and stock
Where each card is in stock
A dash means the card is on the waitlist in that region. The price is identical in all three, so choose on latency and stock, nothing else.
