Frequently Asked Questions
How much VRAM does Qwen3 235B A22B Thinking 2507 need?
Qwen3 235B A22B Thinking 2507 requires 141.6 GB of VRAM at Q4_K_M, or 470.7 GB at BF16. Full 262K context adds up to 25.0 GB (166.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 235.1B × 4.8 bits ÷ 8 = 141.1 GB
KV Cache + Overhead ≈ 0.5 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 ≈ 25.5 GB (at full 262K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Qwen3 235B A22B Thinking 2507?
No — Qwen3 235B A22B Thinking 2507 requires at least 71.0 GB at IQ2_XS, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for Qwen3 235B A22B Thinking 2507?
For Qwen3 235B A22B Thinking 2507, Q4_K_M (141.6 GB) offers the best balance of quality and VRAM usage. Q5_K_S (162.1 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XS at 71.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Qwen3 235B A22B Thinking 2507 on a Mac?
Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run Qwen3 235B A22B Thinking 2507, the smallest at IQ2_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 141.6 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (192 GB).
Can I run Qwen3 235B A22B Thinking 2507 locally?
Yes — Qwen3 235B A22B Thinking 2507 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Qwen3 235B A22B Thinking 2507?
At Q4_K_M, Qwen3 235B A22B Thinking 2507 can reach ~46 tok/s on AMD Instinct MI350X. 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 → 13.4 GB active ÷ (8000 × 0.65) = 2.57 ms, plus 94 layers × 0.055 ms = 5.17 ms, so 1000 ÷ 7.74 ms = ~129 tok/s
Estimated speed at Q4_K_M (141.6 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Qwen3 235B A22B Thinking 2507?
At Q4_K_M, the download is about 141.06 GB. The full-precision BF16 version is 470.19 GB. The smallest option (IQ2_XS) is 70.53 GB.
Which GPUs can run Qwen3 235B A22B Thinking 2507?
No single consumer GPU has enough VRAM to run Qwen3 235B A22B Thinking 2507 at Q4_K_M (141.6 GB). Multi-GPU or professional hardware is required.
Which devices can run Qwen3 235B A22B Thinking 2507?
4 devices with unified memory can run Qwen3 235B A22B Thinking 2507 at Q4_K_M (141.6 GB), including Mac Pro M2 Ultra (192 GB), Mac Studio (M3 Ultra, 256GB), Mac Studio (M3 Ultra, 512GB), Mac Studio M2 Ultra (192 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
