RTX

RTX is a brand used by NVIDIA for a family of graphics processing units that support real-time ray tracing and AI-accelerated rendering. The RTX designation began with the GeForce RTX line introduced in 2018 and now spans consumer GeForce GPUs and professional RTX A-series products. RTX cards combine traditional rasterization with dedicated hardware that speeds up ray tracing and AI workloads.

Key features include RT Cores, which accelerate real-time ray tracing calculations for lighting, reflections, and shadows, and Tensor Cores, which run AI workloads such as Deep Learning Super Sampling (DLSS). DLSS uses neural networks to render fewer pixels and upscale the image, improving frame rates and image quality. DLSS has evolved through multiple revisions, with DLSS 3 introducing Frame Generation to create additional frames via AI.

RTX has evolved across generations. The initial GeForce RTX 20-series (based on the Turing architecture) introduced hardware-accelerated ray tracing and DLSS. The GeForce RTX 30-series (Ampere) improved ray tracing performance and DLSS capabilities. The GeForce RTX 40-series (Ada Lovelace) added further enhancements, including DLSS 3 and more capable RT Cores. In professional markets, NVIDIA extended RTX branding to workstations with the RTX A-series, such as the RTX A6000, targeting visualization, simulation, and AI workflows.

Other related features include RTX IO, a storage-acceleration technology intended to streamline asset streaming from fast storage to the GPU, and high-memory-bandwidth designs suitable for demanding workloads. RTX is used in gaming, content creation, and professional visualization, influencing both consumer experiences and production pipelines.
