Estimates: model weights plus 20% for KV cache and runtime overhead, at short context lengths. Long contexts and large batches need more. Rows marked “tight” hold the weights but not that full margin. A ×N figure is the total VRAM across N of these GPUs and makes no claim about interconnect throughput.

Frequently asked questions

How much does the Instinct MI325X cost per hour?
The Instinct MI325X starts at $2.25 per GPU-hour, with a median of $3.05 across 5 available configurations. Actual pricing depends on the provider, region, and whether you rent on-demand, spot or reserved.
Which cloud providers offer the Instinct MI325X?
2 providers currently list the Instinct MI325X: Cyfuture AI, TensorWave. Compare their hourly pricing, regions and machine specs in the table above.
How much VRAM does the Instinct MI325X have?
The Instinct MI325X comes with 256 GB of VRAM, which determines the largest models and batch sizes it can hold in memory for training and inference.
Which LLMs can I run on the Instinct MI325X?
With 256 GB of VRAM, a single Instinct MI325X can serve models such as DeepSeek V4 Flash, Solar Open2 250B, Qwen3 235B-A22B, Laguna-S 2.1. The table above lists the estimated VRAM for each model at 16-bit, 8-bit and 4-bit precision, including the multi-GPU configurations needed for larger models.
What's the biggest LLM I can run on multiple Instinct MI325X GPUs?
The largest models we track that fit across several Instinct MI325X cards are Kimi K3 on 8 GPUs at 4-bit, DeepSeek V4 Pro on 8 GPUs at 4-bit, Kimi K2.5 on 4 GPUs at 4-bit. A multi-GPU configuration means you rent and pay for every card for the whole run, and splitting a model across cards costs throughput as well: the GPUs exchange activations on every token, so performance depends on how fast they are wired together. We do not track interconnect, so check the provider's node specification. The table above gives the smallest configuration for each model at 16-bit, 8-bit and 4-bit precision.
Where is the Instinct MI325X cheapest?
The lowest on-demand price we currently track for the Instinct MI325X is $2.25 per GPU-hour at TensorWave. Because providers update pricing and availability frequently, check the live table above before you launch.
