MI325X from $1.09 per GPU-hour

AMD Instinct with 256 GB of HBM3e — the largest memory pool in this catalogue. On ROCm-native stacks it holds models that would otherwise need several NVIDIA GPUs and the interconnect that goes with them.

A region with zero free GPUs still accepts reserved capacity requests — we hold hardware for a term rather than sell what is already taken.

Memory planning

What fits in 256 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.

This is an estimate for weights, not a benchmark.

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.

FAQ

MI325X — the questions that come up

How much does an MI325X cost per hour?

Spot is $1.09 per GPU-hour and on-demand is $1.59, both billed per minute — every started minute costs the hourly price divided by 60, so $0.0182 on spot. Reserved capacity is $1.19 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×, 8× — up to 8 MI325X 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 1× MI325X ($1.09 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 East (Virginia). Prices are identical in every region; pick the one closest to your data.

How often is a spot MI325X 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.

Anything else about this model? Ask an engineer — the same people run the nodes.
