This setup is broadly balanced for this model.
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.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Yes, NVIDIA A16 64GB can run Mixtral 8x22B at Q2_K quantization (Runs with offload (needs ~1.4 GB host RAM)). The recommended Q4_K_M requires 96.7 GB which exceeds available memory, but at Q2_K it needs only 65.7 GB. Expected decode speed: 10.7 tok/s.
Mixtral 8x22B (141B parameters) requires approximately 96.7 GB at Q4_K_M quantization. On NVIDIA A16 64GB, it fits at Q2_K using 65.7 GB.
The recommended quantization is Q4_K_M, but on NVIDIA A16 64GB the best fitting quantization is Q2_K, which uses 65.7 GB.
On NVIDIA A16 64GB, Mixtral 8x22B achieves approximately 10.7 tokens per second decode speed with a time-to-first-token of 18149ms using Q2_K quantization.
For coding workloads, Mixtral 8x22B on NVIDIA A16 64GB receives a F grade with 3.6 tok/s and 4K context.
On NVIDIA A16 64GB, Mixtral 8x22B can safely use up to 8K tokens of context at Q2_K quantization. The model's official context limit is 66K, but available memory constrains the safe maximum.
Buy headroom, not only minimum fit. A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
