Pricing & availability
How this list works
The two views
By provider shows one card per company, placed where its best offer ranked. By configuration lists every offer.
Order
What you can rent comes first: in stock, then waitlist, then not reported, then out of stock. Priced offers rank ahead of quote-only, and on-demand ahead of other billing types.
Within a group, five factors set the order:
- Location: datacenter proximity, blended with provider HQ.
- Price: hourly price, per GPU and in total.
- Billing type: reserved ahead of spot, spot ahead of quote-only.
- Specs: more VRAM, vCPUs and RAM.
- Provider diversity: a provider's repeat rows rank slightly lower, so one company can't take all the top spots.
Search
We match the provider, its country, GPU model, form factor, billing type, availability and instance name. Matching is partial and case-insensitive. Everyday words work too, so "interruptible" finds spot and "sold out" finds out of stock.
Transparency and funding
- Ads and sponsors: Paid placements sit at the top of the list and are always labeled as sponsored content. Sponsorship never influences the organic ranking itself.
- Affiliates: Affiliate links are marked. We may earn a commission if you click them, but commissions never affect the order.
- Prices: Shown in USD, converted at daily reference rates where a provider publishes in another currency. A month means 720 hours. How we estimate costs.
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Verify before provisioning. More on how we price.
What can the RTX 4090 run?
One RTX 4090 has 24 GB of VRAM. In practice, that's enough memory for roughly 28B parameters at 4-bit or 6B at 16-bit, assuming a 32K context. Below are some open-weight LLMs, with the estimated memory and GPUs each one needs.

Estimates based on the median on-demand rate. Memory is weights plus FP8 KV cache at 32K context per request (FP16/BF16 in the 16-bit column). GPU counts assume 90% of advertised VRAM is usable. No guarantee of runtime support, usable performance, or that a matching quantized build exists. How we estimate costs.

Who has the cheapest RTX 4090?
-
The cheapest verified in-stock on-demand RTX 4090 tracked by GetDeploying is $0.23 per GPU per hour from Theta EdgeCloud. Cheapest verified in stock on other billing types: reserved $0.27 (12 mo) from Novita and spot $0.12 from Vast.ai.
How much does the RTX 4090 cost per month?
-
At 720 hours per month, one RTX 4090 costs an estimated $324 at the median on-demand price. Cheapest verified in stock: $166 per month on-demand, $194 reserved (12 mo), $86 spot.
Where can I rent an RTX 4090?
-
GetDeploying currently tracks RTX 4090 configs from 20 providers. The cheapest verified in-stock on-demand configs come from Theta EdgeCloud, Vast.ai, Lium and Novita. See the full price comparison above for every provider and config.
Are RTX 4090 prices going up or down?
-
As of September 14, 2026, the median on-demand price has fallen about 11% over the past 90 days to $0.45 per GPU per hour, and about 14% over the past 12 months.
How many RTX 4090 GPUs do I need?
-
One RTX 4090 runs models up to roughly 28B parameters at 4-bit quantization or 6B at 16-bit, assuming a 32K context. Larger models run across multiple GPUs: the model table above shows the estimated memory and GPU count for popular open-weight LLMs.
Why choose the RTX 4090?
-
24GB GDDR6X with Ada Lovelace FP8 Tensor Cores. Highest-performing consumer GPU of the Ada generation. Can run 13B parameter models at FP16 or 30B+ quantized. Popular for AI research and Stable Diffusion.
When is the RTX 4090 not a good fit?
-
Consumer GeForce GPU. No ECC memory. 24GB VRAM is limiting for larger LLMs. Subject to Nvidia's consumer EULA, which may restrict data center use. For production inference, consider the L40S.
