Rent an RTX 4090 cloud GPU for image, video and lean AI.
Direct answer
NVIDIA RTX 4090 provides 24 GB of GDDR6X and is a cost-focused choice for ComfyUI, Stable Diffusion, visual workloads and models that fit on one device. GPURento lists a $0.34 per GPU-hour rate with self-service creation in Paris and Frankfurt.

Best for
- ComfyUI and Stable Diffusion workflows
- Image and short-form AI video generation
- Quantized or mid-size single-GPU inference
- Development that benefits from a low hourly reference
Not the best fit when
- Models that require more than 24 GB without offload
- ECC-dependent scientific or enterprise workloads
- Multi-GPU training that requires data-center interconnects
Decision method
What to verify before you deploy capacity.
The content below separates published specifications, GPURento catalog references and decisions that still require a workload benchmark.
01
24 GB is the first constraint
A 4090 is attractive only when the complete workload fits. Count model weights, activations, VAE, ControlNet, LoRA modules, KV cache and runtime overhead. CPU or disk offload can make a workflow run, but may erase the speed advantage.
- Test the exact checkpoint and resolution
- Leave memory headroom for peak steps
- Persist models only when reuse justifies storage cost
02
Measure cost per output
For image and video work, compare seconds and dollars per accepted output at the same resolution, step count and quality settings. Hourly price without a repeatable workflow does not tell you which GPU is economical.
03
Use a data-center GPU when reliability features matter
RTX 4090 is a GeForce product. Workloads that require ECC memory, data-center support characteristics or high-speed multi-GPU topology are better evaluated on A100, H100, H200 or L40S.

Questions
Clear answers, including the limits.
How much is RTX 4090 cloud rental on GPURento?+
The catalog starts at $0.34 per RTX 4090 GPU-hour in Paris or Frankfurt. Storage and optional services are accounted for separately.
Can RTX 4090 run ComfyUI?+
Yes, many ComfyUI image workflows fit within 24 GB. Large video models, high resolutions or multiple auxiliary models can exceed that limit, so test the exact graph.
RTX 4090 or RTX 5090 for cloud AI?+
RTX 5090 adds 32 GB of memory and a newer architecture at a higher reference rate. Choose it when the extra 8 GB removes offload or enables a larger workflow.
Sources and scope
Last reviewed September 1, 2026. GPURento rates are current catalog references; provisioning state remains visible in the workspace, and manufacturer specifications do not substitute for workload benchmarks.

Deployment plan
Start with the workflow, then deploy the 4090.
Confirm that 24 GB is enough, fund the workspace and choose the exact container and region configuration.
