Which should you buy?
Buy the RX 7800 XT if you want the faster card: it's 6% ahead at 4K. The RTX 4070 is the better buy only if it costs at least 6% less, the gap at 1440p, because then it delivers more frames per dollar. Ray tracing is the exception: there the RTX 4070 leads by 35%.
Buy the RX 7800 XT if…
- you want the most FPS: it's 6% faster at 4K and 6% at 1440p.
- you play at 4K or use high-resolution texture packs: 16 GB of VRAM vs 12 GB.
Buy the RTX 4070 if…
- you play with ray tracing: 48 vs 36 FPS at 1440p.
- it costs at least 6% less than the RX 7800 XT, which makes it the better value per frame.

RX 7800 XT vs RTX 4070: quick answers
Is the RX 7800 XT faster than the RTX 4070?
Yes. The RX 7800 XT is about 6% faster at 4K and 6% faster at 1440p in AAA games at High settings. With ray tracing on at 1440p the RX 7800 XT gets about 36 FPS and the RTX 4070 48 FPS.
How many FPS do the RX 7800 XT and RTX 4070 get?
With a Ryzen 7 9800X3D at High settings in AAA games, the RX 7800 XT averages about 126 FPS at 1080p, 88 at 1440p and 54 at 4K. The RTX 4070 averages 119, 84 and 51 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.
What CPU do I need for the RX 7800 XT or RTX 4070?
To keep the CPU bottleneck under 10% at 1440p, the RX 7800 XT needs a Ryzen 5 3600 or faster and the RTX 4070 needs a Ryzen 5 3600 or faster. At 1080p you need a faster CPU for the same result, and at 4K a slower one is fine. A slower CPU narrows the gap between the RX 7800 XT and the RTX 4070.
