Gaming performance
Gaming score: geometric mean of in-game FPS, normalized so the RTX 5090 = 100. Render and synthetic scores are in the Benchmarks section below.
Gaming scores are normalised performance indexes derived from Tom’s Hardware’s published GPU benchmarks. Performance per dollar and per watt are our own calculations on top of that data.
1080p Gaming
1440p Gaming
4K Gaming
The Radeon RX 6600 scores 32.5 at 1080p, 16.9 at 1440p, and 11.6 at 4K on a scale where 100 = the fastest GPU we test (RTX 5090). These scores apply to all board versions of this chip.

Local AI performance
What the Radeon RX 6600 can run on your own machine, and how fast.
Largest model it can run (8K context)
- Q4 (the usual choice, near-original quality)
- ~9.3B
- Q8 (closer to original, half the model size)
- ~5.3B
- FP16 (unquantised, for training and research)
- ~2.8B
Parameter counts the card holds with room for an 8K conversation, counting the model weights plus its attention cache. A longer conversation needs more memory, so it lowers these figures.
Speed & value
- Speed, 8B model at Q4
- 36-42 tok/s
- Memory bandwidth
- 224 GB/s
- Price per GB of VRAM
- $57.38
Generation speed tracks memory bandwidth, because every word produced reads the whole model from memory. Shown as a range.
Models that fit, at Q4
| Model | Size | Memory needed | Est. speed |
|---|---|---|---|
| Glm4 9B | 9.4B | 5.8GB | 30-35 tok/s |
| Yi 9B | 8.8B | 5.8GB | 33-38 tok/s |
| Yi Coder 9B | 8.8B | 5.8GB | 33-38 tok/s |
Popular models small enough for this card at Q4, one per family. Speed is left blank for mixture-of-experts models, where a bandwidth estimate is not reliable enough to publish.
