Frequently Asked Questions
- How much VRAM does Qwen3 30B A3B.w8a8 need?
Qwen3 30B A3B.w8a8 requires 18.7 GB of VRAM at Q4_K_M, or 61.5 GB at BF16. Full 41K context adds up to 1.9 GB (20.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 30.6B × 4.8 bits ÷ 8 = 18.3 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 2.3 GB (at full 41K context)
VRAM usage by quantization
Q4_K_M18.7 GBQ4_K_M + full context20.6 GB- Can NVIDIA GeForce RTX 4090 run Qwen3 30B A3B.w8a8?
Yes, at Q5_K_M (22.2 GB) or lower. Higher quantizations like Q6_K (25.6 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Qwen3 30B A3B.w8a8?
For Qwen3 30B A3B.w8a8, Q4_K_M (18.7 GB) offers the best balance of quality and VRAM usage. Q5_K_M (22.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 13.4 GB.

- Can I run Qwen3 30B A3B.w8a8 on a Mac?
Qwen3 30B A3B.w8a8 requires at least 13.4 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 Qwen3 30B A3B.w8a8 locally?
Yes — Qwen3 30B A3B.w8a8 can run locally on consumer hardware. At Q4_K_M quantization it needs 18.7 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Qwen3 30B A3B.w8a8?
At Q4_K_M, Qwen3 30B A3B.w8a8 can reach ~100 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~173 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 ÷ 18.7 × 0.65 = ~329 tok/s
Estimated speed at Q4_K_M (18.7 GB)
~329 tok/s~173 tok/s~329 tok/s~304 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
