Why rent the RTX 4090.
CryptGPU rents dedicated NVIDIA RTX 4090 servers with 1, 2 or 4 GPUs at $269 per GPU per month (about $0.37 per GPU-hour), 30% below the market median, paid in Bitcoin, Ethereum, USDT, Monero or Litecoin with no KYC. The GeForce RTX 4090 remains one of the most used GPUs for affordable AI work: 24 GB of GDDR6X, FP8-capable tensor cores and RT cores. It suits Stable Diffusion-class models, 7B–14B LLMs in 16-bit, larger ones quantized, and GPU rendering.
- 24 GB GDDR6X
Enough for 13B models in FP8 or 30B in 4-bit.
- Low monthly price
$269 per card per month.
- Mature software support
Widely used, well-supported by AI and rendering tools.

Which models fit on RTX 4090 servers.
Smallest server that holds each model, by precision. Rule of thumb with headroom for the KV cache; long contexts and large batches need more.

RTX 4090 rental FAQ.
More in the full FAQ.
How much does it cost to rent an RTX 4090 per month?
At CryptGPU, the RTX 4090 costs $269 per GPU per month, about $0.37 per GPU-hour over 730 hours and 30% below the market median of $387. A server with 4 GPUs costs $1,076 a month. The price is fixed for the paid month: no hourly metering, no setup fee.
Can I pay for an RTX 4090 server with Bitcoin or Monero, without KYC?
Yes. Every CryptGPU server is paid in crypto: BTC, ETH, USDT, XMR or LTC (USDT on Tron or Ethereum). There is no KYC: no ID documents, no selfie. Your server is online in under 10 minutes once the payment is confirmed on-chain. Paying with crypto
What can I run on one RTX 4090?
Image models like SDXL-class and FLUX-class in FP16, and LLMs up to about 14B in FP8 or 30B in 4-bit by our rule of thumb.
Why choose it over the RTX 5090?
It costs $60 less per month. The 5090 is faster and has 8 GB more memory.
How many per server?
1, 2 or 4 cards.
