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.

Inference speed
Estimated decode speed (tokens/sec) for DeepSeek V3.2 at Q4_K_M across popular GPUs and Apple Silicon, including multi-GPU rigs, using the fastest local runtime per device. Fastest is Mac Studio M3 Ultra 256GB at ~3 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Copy-paste commands to run DeepSeek V3.2 on your machine.
Run
ollama run deepseek-v3.2Yes, AMD Instinct MI350X 288GB can run DeepSeek V3.2 at Q2_K quantization (Runs with offload (needs ~3.5 GB host RAM)). The recommended Q4_K_M requires 439.5 GB which exceeds available memory, but at Q2_K it needs only 291.9 GB. Expected decode speed: 44.2 tok/s.
DeepSeek V3.2 (671B parameters) requires approximately 439.5 GB at Q4_K_M quantization. On AMD Instinct MI350X 288GB, it fits at Q2_K using 291.9 GB.
The recommended quantization is Q4_K_M, but on AMD Instinct MI350X 288GB the best fitting quantization is Q2_K, which uses 291.9 GB.
On AMD Instinct MI350X 288GB, DeepSeek V3.2 achieves approximately 44.2 tokens per second decode speed with a time-to-first-token of 4381ms using Q2_K quantization.
For coding workloads, DeepSeek V3.2 on AMD Instinct MI350X 288GB receives a F grade with 14.0 tok/s and 4K context.
On AMD Instinct MI350X 288GB, DeepSeek V3.2 can safely use up to 4K tokens of context at Q2_K quantization. The model's official context limit is 128K, 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.
