Radeon RX 7900 XTX vs GeForce RTX 4080: In-Depth Breakdown
Performance: Radeon RX 7900 XTX vs GeForce RTX 4080
The GeForce RTX 4080 and Radeon RX 7900 XTX post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to 4K with upscaling and native 1440p gaming.
Price & Value
Right now the GeForce RTX 4080 starts at $899 EUR against $1,099 EUR for the Radeon RX 7900 XTX. Despite being slower, the GeForce RTX 4080 offers the better performance-per-dollar (~20% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 4080 is trading below its $1,199 EUR MSRP — a genuine deal. The Radeon RX 7900 XTX still sits about $100 EUR above its $999 EUR MSRP.
Power & Efficiency
The GeForce RTX 4080 sips power at 320W next to the Radeon RX 7900 XTX's 355W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU.
VRAM & Future-Proofing
The Radeon RX 7900 XTX's 24GB (vs 16GB on the GeForce RTX 4080) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 4080 brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 7900 XTX offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce RTX 4080 or Radeon RX 7900 XTX?
Choose the Radeon RX 7900 XTX if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 4080 stretches your money further for near-identical performance.
