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.

Ecosystem and included software

NVIDIA Reflex (minimum latency in eSports)
NVENC AV1 (cinematic quality encoding)
NVIDIA Broadcast (AI for camera and microphone)
