Manufacturer description

The PowerColor Red Devil AMD Radeon RX 7900 XTX graphics card is built for high-resolution gaming and memory-heavy workloads. It pairs 24GB of GDDR6 memory, running at 20.0 Gbps, with a wide 384-bit memory interface. That leaves a lot of room for 4K texture packs, large mod lists and VRAM-hungry creative or local AI projects. The card has 6144 stream processors and two clock profiles. In OC mode it runs a 2395 MHz game clock and boosts up to 2565 MHz. Silent mode lowers those to 2330 MHz and 2525 MHz, so you give up a little clock speed for quieter running. For displays, you get one HDMI 2.1…

Which local LLMs fit in 24 GB?

24 GB holds a 30–35B model at Q4 entirely in VRAM — the step where 27B-class models stop spilling to system RAM.

  • ✅ 7–9B models (Llama 3.1 8B, Qwen 3 8B) — fits at Q4
  • ✅ 12–14B models (Qwen 3 14B, Phi-4) — fits at Q4
  • ✅ 20–27B models (Gemma 3 27B, Mistral Small) — fits at Q4
  • ✅ 30–35B models (Qwen 3 32B, QwQ 32B) — fits at Q4
  • ❌ 70B models (Llama 3.3 70B, Qwen 2.5 72B) — needs 48 GB+

Across 9 community runs from 8 sources, the Radeon RX 7900 XTX generates a median 138.6 tok/s on 7–9B models at Q4 (per llama.cpp GitHub issue #20934).
