Frequently Asked Questions
Is the RX 7800 XT better than the RTX 4070 for 1440p gaming?
For pure rasterization, the RX 7800 XT delivers 92–95% of RTX 4070 performance for $150 less with more VRAM. For ray tracing specifically, the RTX 4070 wins by 39–45%. The better card depends entirely on whether you use ray tracing.
Does AMD FSR work as well as Nvidia DLSS?
Nvidia DLSS 3 Quality mode generally produces sharper output than FSR 3 Quality. However, FSR works on any GPU including Nvidia cards, making it more universal. For RTX owners, DLSS 3 is superior. For AMD owners or those who want cross-platform upscaling support, FSR is the practical choice.
Which has better driver support — AMD or Nvidia?
Nvidia’s GeForce drivers are more mature with fewer launch-day issues. AMD’s Adrenalin drivers have improved greatly but occasionally have compatibility issues with new AAA releases. For a reliable plug-and-play experience, Nvidia’s ecosystem is more stable.
