NVIDIA RTX 4090

The RTX 4090 starts at $0.12 per GPU-hour, with a median of $0.51 across 62 available configurations. Actual pricing depends on the provider, region, and whether you rent on-demand, spot or reserved.

6 providers currently list the RTX 4090: Sesterce Cloud, Runcrate, Novita AI, Omega Gradient, Vast.ai, Runpod. Compare their hourly pricing, regions and machine specs in the table above.

The RTX 4090 comes with 24 GB of VRAM, which determines the largest models and batch sizes it can hold in memory for training and inference.

With 24 GB of VRAM, a single RTX 4090 can serve models such as GLM-4.7 Flash, Qwen3.6 27B, Mistral Small 3.2 24B, gpt-oss-20b. The table above lists the estimated VRAM for each model at 16-bit, 8-bit and 4-bit precision, including the multi-GPU configurations needed for larger models.

The largest models we track that fit across several RTX 4090 cards are DeepSeek V4 Flash on 8 GPUs at 4-bit, Solar Open2 250B on 14 GPUs at 8-bit, Qwen3 235B-A22B on 8 GPUs at 4-bit. A multi-GPU configuration means you rent and pay for every card for the whole run, and splitting a model across cards costs throughput as well: the GPUs exchange activations on every token, so performance depends on how fast they are wired together. We do not track interconnect, so check the provider's node specification. The table above gives the smallest configuration for each model at 16-bit, 8-bit and 4-bit precision.

The lowest on-demand price we currently track for the RTX 4090 is $0.12 per GPU-hour at Vast.ai. Because providers update pricing and availability frequently, check the live table above before you launch.
