AMD Radeon RX 7900 XTX: 24 GB, what it runs and what it costs

Name: AMD Radeon RX 7900 XTX
Brand: AMD

Specs checked Sep 20, 2026 · Aliteq Team · How we compute this

The short answer

The AMD Radeon RX 7900 XTX has 24 GB of VRAM and 960 GB/s of memory bandwidth (2022). At Q4_K_M quality or better with an 8K context it runs 31 of the open models we track; the largest that fits with room to spare is Qwen3.6 35B-A3B (MoE). We don't see it for rent on the providers we track right now.

Which AI models run on the AMD Radeon RX 7900 XTX

Computed by our VRAM engine for an 8K context: the best quality each model fits at in 24 GB. Speeds are upper-bound estimates from memory bandwidth, not benchmarks.

AMD Radeon RX 7900 XTX: common questions

How much VRAM does the AMD Radeon RX 7900 XTX have?

24 GB, with 960 GB/s of memory bandwidth, per the maker's specification.

What is the biggest AI model the AMD Radeon RX 7900 XTX can run?

Of the open models we track, Qwen3.6 35B-A3B (MoE) is the largest that fits at Q4_K_M or better with an 8K context and room to spare (about 21 GB of 24 GB). Bigger models only fit at lower-quality quants or need more memory.

Can I rent an AMD Radeon RX 7900 XTX in the cloud?

We don't see it on Vast.ai, Runpod or the other providers we track right now. The cloud GPU table lists every card that is for rent.

Is 24 GB enough?

4K gaming; 24–32B local models at Q4 with room for context.
