Can Desktop PC · Radeon RX 7900 XT · 32 GB RAM run GLM-4.7-Flash (30B-A3B)?
20 GB VRAM + 32 GB RAM · 800 GB/s memory bandwidth · GLM-4.7-Flash (30B-A3B) has 31.2B parameters (3B active per token).
Short answer
Yes, excellent for chat; borderline for 64K-token documents.
Best quantization for chat: Q3_K_M (14 GB of weights) on Lemonade. Generation: 190–320 tok/s, leaving about 3.5 GB free for your other apps.
How it rates for each workload
Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Speeds are bandwidth-based estimates; no direct benchmark exists for this pair. “First reply” is the time to read the workload’s opening prompt. How we calculate
Get it running
Copy-paste commands for the Q3_K_M build with a 32K context. Ollama and llama.cpp download the file straight from Hugging Face.
ollama run hf.co/unsloth/GLM-4.7-Flash-GGUF:Q3_K_M
Downloads 14.61 GB (Q3_K_M). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=32768 before `ollama serve` for long prompts.
