Frequently Asked Questions
How much VRAM does Qwen3 30B A3B Thinking 2507 need?
Qwen3 30B A3B Thinking 2507 requires 19.8 GB of VRAM at Q4_K_M, or 66 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 30B × 4.8 bits ÷ 8 = 18 GB
KV Cache + Overhead ≈ 1.8 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.
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Qwen3 30B A3B Thinking 2507?
Yes, at Q5_K_M (23.5 GB) or lower. Higher quantizations like Q6_K (27.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Qwen3 30B A3B Thinking 2507?
For Qwen3 30B A3B Thinking 2507, Q4_K_M (19.8 GB) offers the best balance of quality and VRAM usage. Q5_K_M (23.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 14.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Qwen3 30B A3B Thinking 2507 on a Mac?
Yes, but only at lower quantizations. The smallest Mac that can run Qwen3 30B A3B Thinking 2507 is MacBook Pro 14" M3 Pro (18 GB) at Q2_K; 109 of the 156 Macs we list can run it at some quantization. For Q4_K_M (19.8 GB) you need a Mac with more unified memory.
Can I run Qwen3 30B A3B Thinking 2507 locally?
Yes — Qwen3 30B A3B Thinking 2507 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Qwen3 30B A3B Thinking 2507?
At Q4_K_M, Qwen3 30B A3B Thinking 2507 can reach ~100 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~177 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 → 2.0 GB active ÷ (8000 × 0.65) = 0.38 ms, plus 48 layers × 0.055 ms = 2.64 ms, so 1000 ÷ 3.02 ms = ~331 tok/s
Estimated speed at Q4_K_M (19.8 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Qwen3 30B A3B Thinking 2507?
At Q4_K_M, the download is about 18.00 GB. The full-precision BF16 version is 60.00 GB. The smallest option (Q2_K) is 12.75 GB.
Which GPUs can run Qwen3 30B A3B Thinking 2507?
