Compare RTX 4090 prices across 7 cloud providers. On-demand from $0.11/hr.
RTX 4090 market snapshot
verifiedCheapest RTX 4090 confirmed in stock right now: $0.11/hr on Vast.
■ near its 6-month low — at $0.11/hr the RTX 4090 floor price is near its 6-month low — 6-month range $0.11–$0.60/hr.
Bottom line: a relatively good time to rent — the floor price is near its 6-month low.
Most reliably in stock over the last 30 days: Vast, Shadeform. Frequently waitlisted: Theta EdgeCloud, AceCloud.
30-day reliability depth
GPU Finder does not treat availability as a static yes/no flag. For RTX 4090, current stock badges are paired with a 30-day reliability score computed from AvailabilityRecord history, measuring how much covered time each tracked row was reported available.
Strongest reliability signals here: Vast (100%, 24d covered), Shadeform (91%, 30d covered), Runpod (64%, 30d covered).
Caveat: scores stay hidden until a row has at least 48covered hours, and some provider APIs expose coarse capacity levels instead of exact stock counts. Use the score as historical depth beside current availability, not as a guarantee that a GPU will still be allocatable when you click through.
About the RTX 4090
The NVIDIA RTX 4090 is a consumer GPU that has become the de facto choice for individual researchers, small teams, and cost-sensitive inference. Its 24 GB of GDDR6X and Ada Lovelace Tensor Cores deliver performance rivaling datacenter GPUs at a fraction of the cost. The trade-off: no ECC, no NVLink, and a 24 GB VRAM ceiling. But for workloads that fit, nothing else comes close on cost-per-FLOP.

Cloud Pricing Context
The RTX 4090 is the cheapest high-performance GPU in the cloud, starting around $0.18/hr on marketplace providers. It is offered almost exclusively by neocloud and bare-metal providers. For any workload fitting in 24 GB, it consistently delivers the best performance per dollar.
Best For
- Fine-tuning 7B-parameter models with LoRA/QLoRA adapters
- Local-quality inference for Llama, Mistral, and similar models
- Rapid prototyping where cost matters more than ECC
- Stable Diffusion, ComfyUI, and image generation workloads
Price History & Comparison
Spot pricing decision guide
Treat spot as a risk-adjusted capacity decision, not just a cheaper number.
per GPU-hour
69% below on-demand floor
fake/equal spot rows suppressed
median hidden until ≥3 rows across ≥2 providers
Cheapest trusted interruptible capacity is on Vast; 1 provider currently report spot-adjacent stock (3227 units/signals visible).
Vast has the strongest 30-day spot-adjacent reliability signal here (100%). See the 30-day reliability depth module for the broader availability history.
There is a valid spot or interruptible row, but not enough trusted history to overstate the signal.
Good fit: checkpointed batch jobs, flexible training, and experiments that can restart. Avoid for production serving, deadline-bound runs, or jobs that cannot tolerate eviction.
Source caveat: Runpod exposes explicit spot fields; Vast is labeled interruptible/bid-floor. Lambda is treated as on-demand-only unless a verified spot field is added.
