Frequently Asked Questions

How much VRAM does Qwen2 7B need?

Qwen2 7B requires 5.0 GB of VRAM at Q4_K_M, or 15.7 GB at BF16. Full 131K context adds up to 7.4 GB (12.4 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 7.6B × 4.8 bits ÷ 8 = 4.6 GB

KV Cache + Overhead ≈ 0.4 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 ≈ 7.8 GB (at full 131K context)

Can I run Qwen2 7B on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Qwen2 7B, the smallest at IQ3_S. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 5.0 GB of usable unified memory (RAM minus macOS overhead), from Mac Mini M2 Pro (16 GB).

Can I run Qwen2 7B locally?

Yes — Qwen2 7B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Qwen2 7B?

At Q4_K_M, Qwen2 7B can reach ~962 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~131 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

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

Example: NVIDIA B200 → 8000 ÷ 4.99 × 0.65 = ~1042 tok/s
