Key technologies of the RTX 4090
Upscaling, ray tracing and software ecosystem — what sets each architecture apart.
AI Upscaling
DLSS 4 (AI, Multi Frame Gen on RTX 50)
DLSS uses the GPU's Tensor Cores to reconstruct frames with AI. With the RTX 4090 you get up to 2-3× more fps without noticeable visual loss in Quality or Balanced mode.
Ray Tracing
NVIDIA RTX with DXR · dedicated hardware ray tracing
At this tier, ray tracing is a pleasure: you can enable it at maximum quality in most games and maintain 60+ fps at 1440p, even 4K with upscaling.
