Qwen 2.5 32B needs 19 GB VRAM at Q4. The RTX 4070 Ti Super 16GB has 16 GB.
🌐 Qwen 2.5 32B (Alibaba) is a 32B-parameter model for advanced coding, math, long-form reasoning. One of the best open 32B models, rivals much larger ones at code. The question is whether the RTX 4070 Ti Super 16GB’s 16 GB of VRAM can hold it — here’s the exact math.
VRAM requirements
| Quantization | VRAM needed | RTX 4070 Ti Super 16GB |
|---|---|---|
| Q4_K_M (recommended) | 19 GB | ❌ |
| Q8_0 (near-lossless) | 34 GB | ❌ |
Why it won’t fit (and what to do)
Qwen 2.5 32B needs 19 GB at Q4 but the RTX 4070 Ti Super 16GB has only 16 GB — you’re 3 GB short. You can offload layers to system RAM, but expect single-digit tokens/sec (painfully slow for chat).
