Thermals and Power Consumption
The GeForce RTX 4080 is miles ahead of the RX 7900 XTX in power efficiency. It is faster and more power efficient in ray tracing, drawing ~20% less. The reference 7900 XTX holds its thermals steady under 70C, thanks to a robust vapor chamber.
GPU | Peak Temp (C) | Peak power (W) | TBP |
---|---|---|---|
NVIDIA RTX 4080 | 69C | 303W | 320W |
AMD RX 7900 XTX | 70C | 366W | 355W |
Conclusion
The Radeon RX 7900 XTX is faster than the GeForce RTX 4080 across all resolutions in rasterized gaming. At 4K, it holds a lead of 7% over the RTX 4080 despite costing $50-100 less. Ray tracing is another story, however. The GeForce GPU rips through its rival with 11 definitive wins across 11 games, recording an average lead of 23% over the 7900 XTX.
