01 Side by side

What is the difference between the RTX 4090 and the RTX A6000?

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 RTX A6000 carries 24 GB more memory, so on capacity alone it is the better card. The RTX 4090 supports FP8 and the RTX A6000 does not, which roughly halves the memory a quantised model needs and is the largest practical difference between the two. Bandwidth is 1.01 TB/s against 768 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 4090 costs 34% more per month, $390 against $290, or $0.54 against $0.40 per GPU-hour.

04 Questions

RTX 4090 against RTX A6000

Is the RTX 4090 better than the RTX A6000?

For anything memory-bound the RTX 4090 wins: 24 GB at 1.01 TB/s against 48 GB at 768 GB/s. For work that already fits in 48 GB the RTX A6000 is the better buy, because it costs $290 a month against $390 and the job finishes either way.

What is the price difference between the RTX 4090 and the RTX A6000?

At GPU Rent Hub the RTX 4090 is $390 a month and the RTX A6000 is $290, a gap of $100. Weekly terms are $110 and $82. Both prices are flat and include power, cooling, a public IPv4 and 20 TB of outbound traffic.

How much VRAM does the RTX 4090 have compared to the RTX A6000?

The RTX 4090 has 24 GB of GDDR6X and the RTX A6000 has 48 GB of GDDR6 ECC. The workhorse: 24 GB, 1 TB/s, and the largest stock 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 265 RTX 4090 and 65 RTX A6000 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 4090 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.
