A4000 vs RTX 4000
The A4000 has 16GB and Ampere Tensor Cores with BF16 and TF32, the RTX 4000 has 8GB and Turing. Both are single-slot professional cards, so the A4000 is the newer option at the same form factor.

Heads up: We do our best to keep these specs & prices accurate. However, cloud costs may fluctuate based on region, usage, and other factors not listed here. These are estimates based on common setups and are for informational purposes only. Always verify current rates & exact specs with the provider before provisioning.
Offers and availability
How this list works
Order
Each provider appears once per GPU. We pick the one configuration that speaks for that provider, and rank on it in this order:
- Availability: in stock, then waitlist, then not reported, then out of stock. A price you can act on outranks a cheaper one you cannot.
- Billing type: on-demand first, then reserved, then spot, then quote-only. On-demand leads because it is the only rate you can hold without committing to anything.
- Price: the lowest per-GPU hourly rate the provider lists, converted to USD.
The configuration we pick is chosen the same way, availability before billing before price. The rest of that provider's configurations are on the GPU's own page.
Ties sort alphabetically. Reserved rates are not separated by term length, so a three-year commitment can sit above a one-month one: the label beneath each price says which you are looking at. Providers who publish no rate are listed last within their group.
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.
