GTX stands for Giga Texel Shader eXtreme, while RTX stands for Ray Tracing Texel eXtreme. At the same time, these two are not simple technologies to understand; the basic understanding is that they are both meant to be used for graphics-intensive applications such as games and graphic engines, among many other functions. The GTX series will give you a better performance in some games, while the RTX card has additional features, which is a good choice for mid and high-end PCs. The RTX is a good choice as more games support ray tracing, which is a good choice for many generations of gaming laptops.
