Can I run Qwen 14B on a Mac?

Qwen 14B requires at least 6.6 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.

Can I run Qwen 14B locally?

Yes — Qwen 14B can run locally on consumer hardware. At Q4_K_M quantization it needs 9.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Qwen 14B?

At Q4_K_M, Qwen 14B can reach ~312 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~70 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: AMD Instinct MI300X5300 ÷ 9.3 × 0.55 = ~312 tok/s

Estimated speed at Q4_K_M (9.3 GB)

~312 tok/s
~70 tok/s
~233 tok/s
~193 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
