Falcon 40B Instruct needs ~35.0 GB VRAM. AMD Instinct MI60 32GB has 32.0 GB. With Q5_K_M quantization, expect ~12 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.

Offload
10%
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 2.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, AMD Instinct MI60 32GB can run Falcon 40B Instruct with a B grade (Very compromised (needs ~2.5 GB host RAM)). Expected decode speed: 12.0 tok/s.
Falcon 40B Instruct (40B parameters) requires approximately 35.0 GB of memory with Q5_K_M quantization.
The recommended quantization for Falcon 40B Instruct is Q5_K_M, which balances quality and memory efficiency.
On AMD Instinct MI60 32GB, Falcon 40B Instruct achieves approximately 12.0 tokens per second decode speed with a time-to-first-token of 16160ms using Q5_K_M quantization.
For coding workloads, Falcon 40B Instruct on AMD Instinct MI60 32GB receives a B grade with 12.0 tok/s and 4K context.
On AMD Instinct MI60 32GB, Falcon 40B Instruct can safely use up to 4K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
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.
