This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Inference speed
Estimated decode speed (tokens/sec) for Qwen 3 14B at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~152 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.

Yes, MacBook Pro M4 32GB can run Qwen 3 14B with a S grade (Runs well). Expected decode speed: 9.6 tok/s.
Qwen 3 14B (14B parameters) requires approximately 15.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen 3 14B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 32GB, Qwen 3 14B achieves approximately 9.6 tokens per second decode speed with a time-to-first-token of 20135ms using Q4_K_M quantization.
For coding workloads, Qwen 3 14B on MacBook Pro M4 32GB receives a S grade with 9.6 tok/s and 66K context.
On MacBook Pro M4 32GB, Qwen 3 14B can safely use up to 66K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 32GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
