Choose by the constraint that changes the job
These are two complete AWS instances, not interchangeable single-GPU rentals. Use the exact GPU, device count, host memory and region shown below to establish whether each can run the same workload. Confirm software support and the distributed communication path before comparing rental rates.
Compare completion cost, not just hourly price
Run the same model, precision, batch size and data on both feasible configurations. Record completed work, billed runtime and peak memory. Compute-only job cost is the full-instance rate multiplied by billed runtime. A higher-rate instance saves money only when its measured runtime reduction offsets that rate; a hardware specification does not prove that reduction.
Make the result operational
Check quota, capacity and the source observation date for both instances. Keep the purchase model consistent: an interruptible spot observation is not an equivalent on-demand quote. Include recovery time, storage and transfer charges in a deployment budget.
Limitations
The table contains catalogue observations, not current checkout quotes or an end-to-end benchmark. If only one configuration meets your workload requirements, a price ratio alone cannot justify switching.
