Frequently Asked Questions

How much VRAM does Qwen3.6 27B A3B CoderX need?

Qwen3.6 27B A3B CoderX requires 15.7 GB of VRAM at Q4_K_M, or 51.6 GB at BF16. Full 262K context adds up to 2.6 GB (18.3 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 25.6B × 4.8 bits ÷ 8 = 15.4 GB

KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 2.9 GB (at full 262K context)

Can I run Qwen3.6 27B A3B CoderX on a Mac?

Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Qwen3.6 27B A3B CoderX, the smallest at Q2_K. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 15.7 GB of usable unified memory (RAM minus macOS overhead), from Mac Mini M5 Pro (24 GB).

Can I run Qwen3.6 27B A3B CoderX locally?

Yes — Qwen3.6 27B A3B CoderX can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Qwen3.6 27B A3B CoderX?

At Q4_K_M, Qwen3.6 27B A3B CoderX can reach ~119 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~199 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 1.8 GB active ÷ (8000 × 0.65) = 0.355 ms, plus 40 layers × 0.055 ms = 2.200 ms, so 1000 ÷ 2.555 ms = ~391 tok/s

Estimated speed at Q4_K_M (15.7 GB)

~391 tok/s
~199 tok/s
~391 tok/s
~360 tok/s

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