Can I Run GLM-4.7 / GLM-Z1 on AMD Radeon RX 7900 XT?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 15 sierpnia 2026
Yes, comfortably — GLM-4 9B at Q4_K_M needs 7.4 GB at 8K context (5.4 GB weights + 2 GB KV cache/overhead), leaving ~12.6 GB of the AMD Radeon RX 7900 XT's 20 GB, at ~66 tok/s (est.), with room for up to 64K context.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 20 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the AMD Radeon RX 7900 XT: 8K 7.4 GB · 32K 11.1 GB · 125K 25.1 GB ✗. Past 125K it no longer fits 20 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? GLM-4 9B on 8 GB of system RAM, CPU only: runs, but it is tight.
