Can the Radeon RX 9070 XT run GLM-4.7-Flash?
Only with CPU offload at Q4_K_M.
GLM-4.7-Flash is 30B parameters (MoE; all experts resident). At Q4_K_M the weights are about 16.8 GiB; with the 1.5 GiB runtime reserve that is 18.3 GiB against the card's 16GB, about 2.3 GiB more than the card has.
All three quants
16GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 16.8 GiB | 18.3 GiB | Only with CPU offload | short 2.3 GiB |
| Q8_0near-lossless | 29.6 GiB | 31.1 GiB | Only with CPU offload | short 15.1 GiB |
| FP16full weights | 55.9 GiB | 57.4 GiB | Does not fit | short 41.4 GiB |
Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.
The numbers for this pairing
At Q4_K_M the weights take about 16.8 GiB, so with the 1.5 GiB runtime reserve it needs 18.3 GB: 2.3 GB more than the card's 16 GB.
No version of it fits entirely in this card's memory, so it would lean on system RAM and run far slower.
It is a mixture-of-experts model: about 3B of its 30B parameters work on each token, which helps speed, but all of them still have to fit in memory.
The cheapest card on our list that runs it comfortably at Q4 is the Radeon RX 7900 XTX at about $850, against about $810 for this card.
At about $810, this card costs roughly $51 per GB of VRAM.
Running it at its full 304 W board power for 4 hours a day would use about 36 kWh a month, about $6.71 at the US average residential rate of 18.4 cents per kWh (2026-05); real use sits below that ceiling.
Prices are the lowest current listings our tracker saw on Oct 7, 2026, since averages include premium variants; launch prices are marked where we have no listing.
