Qwen 2.5 Math 72B needs ~37.1 GB VRAM. AMD Instinct MI100 32GB has 32.0 GB. With Q2_K quantization, expect ~15 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
40%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 3.8 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, AMD Instinct MI100 32GB can run Qwen 2.5 Math 72B at Q2_K quantization (Very compromised (needs ~3.8 GB host RAM)). The recommended Q4_K_M requires 52.9 GB which exceeds available memory, but at Q2_K it needs only 37.1 GB. Expected decode speed: 14.5 tok/s.
Qwen 2.5 Math 72B (72B parameters) requires approximately 52.9 GB at Q4_K_M quantization. On AMD Instinct MI100 32GB, it fits at Q2_K using 37.1 GB.
The recommended quantization is Q4_K_M, but on AMD Instinct MI100 32GB the best fitting quantization is Q2_K, which uses 37.1 GB.
On AMD Instinct MI100 32GB, Qwen 2.5 Math 72B achieves approximately 14.5 tokens per second decode speed with a time-to-first-token of 13383ms using Q2_K quantization.
For coding workloads, Qwen 2.5 Math 72B on AMD Instinct MI100 32GB receives a F grade with 5.1 tok/s and 4K context.
On AMD Instinct MI100 32GB, Qwen 2.5 Math 72B can safely use up to 4K tokens of context at Q2_K quantization. The model's official context limit is 4K, but available memory constrains the safe maximum.
