What is RTX
Nvidia RTX is a high-end professional visual computing platform created by Nvidia, primarily used for designing complex large scale models in architecture and product design, scientific visualization, energy exploration, and film and video production. Nvidia RTX enables realtime ray tracing. Historically, ray tracing had been reserved to non-real time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows and reflections. RTX runs on Nvidia Volta-, Turing- and Ampere-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.
