Price comparison

Nvidia A4000 logo A4000 Pricing

Barriers to entry are low here. 11 cloud providers list the A4000 with prices starting at just $0.03/hr per GPU (spot instance), making it accessible for testing without a large commitment.

Default ranking

Availability comes first: in stock, then waitlist, then unconfirmed, then out of stock. Offerings without a listed price are ranked below priced ones.

Within each group, our algorithm weighs five factors to find the most relevant matches for you:

  1. Price: We blend total hourly price with price-per-GPU to balance affordability and value.
  2. Specs: We favor offers with higher CPU, RAM, and GPU Memory.
  3. Billing: We favor on-demand billing for simplicity and flexibility over spot instances, reservations, and custom quotes.
  4. Location: We blend both datacenter proximity and provider HQ location. Datacenter location matters for latency, while HQ location matters for compliance and support.
  5. Provider diversity: Each time a provider appears in the list, their subsequent offerings are ranked a little lower, so one provider's offerings don't crowd out the top positions.

Sorting and filtering

Click "View all offerings" to access the full list with sortable columns and filters for billing type, GPU count, vCPUs, and RAM.

Ads and sponsors: Any paid placements are fixed at the top and clearly labeled as sponsored content.

Affiliates: Any affiliate links will be indicated to you as well. We may earn a commission if you click them, but this never influences the ranking order.
