Qwen3 235B A22B — Hardware Requirements & GPU Compatibility
ChatFunctionsQwen3 235B A22B is the largest model in Alibaba Cloud's Qwen 3 series, a Mixture of Experts (MoE) model with 235 billion total parameters and approximately 22 billion active parameters per forward pass. The MoE architecture enables it to deliver performance competitive with the best available open-weight models while requiring significantly less compute per token than a comparably sized dense model. It supports hybrid thinking mode for flexible chain-of-thought reasoning. Due to its massive total parameter count, running Qwen3 235B A22B locally requires substantial VRAM to load all expert weights, typically needing multiple high-end professional GPUs even at reduced precision. In heavily quantized formats it becomes accessible on workstation-class multi-GPU setups. Released under the Apache 2.0 license.

Frequently Asked Questions
How much VRAM does Qwen3 235B A22B need?
Qwen3 235B A22B requires 141.6 GB of VRAM at Q4_K_M, or 470.7 GB at BF16. Full 41K context adds up to 3.8 GB (145.3 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 ≈ 4.2 GB (at full 41K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Qwen3 235B A22B?
No — Qwen3 235B A22B requires at least 100.4 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for Qwen3 235B A22B?
For Qwen3 235B A22B, Q4_K_M (141.6 GB) offers the best balance of quality and VRAM usage. Q5_0 (147.4 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 100.4 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Qwen3 235B A22B on a Mac?
Yes — Mac Pro M2 Ultra (128 GB) and 14 other Macs can run Qwen3 235B A22B, the smallest at Q3_K_L. 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 locally?
Yes — Qwen3 235B A22B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Qwen3 235B A22B?
At Q4_K_M, Qwen3 235B A22B 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?
At Q4_K_M, the download is about 141.06 GB. The full-precision BF16 version is 470.19 GB. The smallest option (Q2_K) is 99.91 GB.
Which GPUs can run Qwen3 235B A22B?
No single consumer GPU has enough VRAM to run Qwen3 235B A22B at Q4_K_M (141.6 GB). Multi-GPU or professional hardware is required.
Which devices can run Qwen3 235B A22B?
4 devices with unified memory can run Qwen3 235B A22B 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.
