Can I run GLM 4.7 Flash on GeForce RTX 4070?
Heavily degraded
Heavily degraded fully on your GeForce RTX 4070 at UD-IQ2_XXS, 8K context, about 59–80 tok/s. Weights 9.79 GB plus 0.41 GB of KV cache — 10.6 GB of 10.9 GB usable.

Assumptions
- Estimate from memory bandwidth, not a benchmark. Decode speed uses 55–75% of peak bandwidth.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- UD-IQ2_XXS size is the real GGUF file size from Hugging Face.
- 0.5 GB is reserved because this GPU also drives a display, then 5% of the rest is left free.
- Speed is quoted at 8K context, not at the maximum context that still fits.
- This quant is IQ1 or IQ2. It can load, but quality is heavily degraded, so it is left off best-fit lists.
