RTX PRO 4500 Blackwell from $0.09 per GPU-hour
RTX PRO 4500 Blackwell is a professional workstation card with ECC memory with 32 GB of GDDR7, built on the Blackwell architecture in 2025. It holds models up to about 9B at FP16, and 30B-class models quantised to 4 bits. Memory bandwidth is 896 GB/s, which is what sets token throughput for inference.
Billed per started minute. 128 GB of GPU memory on a 4× node. Persistent storage $0.08 per GB-month. No egress fees.

A region with zero free GPUs still accepts reserved capacity requests — we hold hardware for a term rather than sell what is already taken.
What fits in 32 GB — and what it costs per hour.
Weights need about 2 GB per billion parameters at FP16 / BF16, 1 GB per billion parameters at FP8, 0.5 GB per billion parameters at INT4. We keep 20% of the memory free for activations, the KV cache and the CUDA context, then take the smallest node that still fits.

Real usage depends on context length, batch size and the serving engine: a long context can add tens of gigabytes of KV cache. Treat the table as the floor, not the ceiling — and if a job is close to the limit, take the next node size or quantise one step further.

RTX PRO 4500 Blackwell — the questions that come up
How much does an RTX PRO 4500 Blackwell cost per hour?
Spot is $0.09 per GPU-hour and on-demand is $0.19, both billed per minute — every started minute costs the hourly price divided by 60, so $0.0015 on spot. Reserved capacity is $0.09 per GPU-hour on a monthly commitment. Storage and egress are not included in that rate: persistent disks are $0.08 per GB-month and there are no egress fees.
How many GPUs can I put in one instance?
Node sizes are 1×, 2×, 4× — up to 4 RTX PRO 4500 Blackwell GPUs in a single virtual machine, with CPU, RAM and local NVMe scaled with the GPU count. The price per GPU is identical at every node size.
Can it run a 70B model?
Yes. At FP8, a 70B model needs about 70 GB for the weights, so it fits on 4× RTX PRO 4500 Blackwell ($0.36 per hour on spot) with roughly 20% of the memory left for activations and the KV cache.
Which regions have it?
Available now in US West (Oregon). Prices are identical in every region; pick the one closest to your data.
How often is a spot RTX PRO 4500 reclaimed?
Over the trailing 30 days, 5–10% of spot instances on this model were reclaimed. You get a 2-minute notice on the metadata endpoint, through a webhook and in the console; the instance is then stopped, never deleted, and the persistent disk stays attached.
