GTX VS RTX GPUs | Nvidia

Giga Texel Shader eXtreme

Nvidia GTX series is based on the Pascal and Turing architecture
GTX excelled in traditional rasterization rendering techniques, delivering high frame rates and smooth gameplay experiences in most modern games & proved efficient for tasks like video editing, graphic design, and 3D rendering.
However, GTX cards lack dedicated hardware for ray tracing, a technology that simulates how light behaves in real life, enhancing visual fidelity and Tensor Cores.
Popular for their value and performance across a range of budgets.

Ray Tracing Texel eXtreme

The Nvidia RTX series is built on advanced Turing and Ampere architecture. 
RT Cores dedicated ray-tracing hardware allows real-time visual realism in games and applications resulting in more realistic lighting, shadows, and reflections.
RTX graphics cards deliver up to 6x faster ray-tracing performance.
Tensor Cores in RTX GPUs enables AI and deep learning capabilities with DLSS.
DLSS stands for Deep Learning Super Sampling graphics technology that uses AI to boost performance by generating more frames
