Frequently Asked Questions
- How much VRAM does CodeQwen1.5 7B need?
CodeQwen1.5 7B requires 4.8 GB of VRAM at Q4_K_M, or 14.9 GB at BF16. Full 66K context adds up to 4.2 GB (8.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.3B × 4.8 bits ÷ 8 = 4.4 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 4.5 GB (at full 66K context)
VRAM usage by quantization
Q4_K_M4.8 GBQ4_K_M + full context8.9 GB- What's the best quantization for CodeQwen1.5 7B?
For CodeQwen1.5 7B, Q4_K_M (4.8 GB) offers the best balance of quality and VRAM usage. Q5_K_S (5.4 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.5 GB.

- Can I run CodeQwen1.5 7B on a Mac?
CodeQwen1.5 7B requires at least 3.5 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 CodeQwen1.5 7B locally?
Yes — CodeQwen1.5 7B can run locally on consumer hardware. At Q4_K_M quantization it needs 4.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is CodeQwen1.5 7B?
At Q4_K_M, CodeQwen1.5 7B can reach ~921 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~137 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 ÷ 4.8 × 0.65 = ~1088 tok/s
Estimated speed at Q4_K_M (4.8 GB)
~1088 tok/s~137 tok/s~1088 tok/s~921 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
