The RTX series is the most powerful series of GeForce video cards ever. It's also called the NVIDIA 20 series. These video cards allow your computer to handle even the latest games in a high resolution. The RTX 20 graphics are mainly focused on ray tracing. This is a technique that makes light and reflections a lot more realistic in your games. The series consists of the RTX 2080, RTX 2070, and RTX 2060. The higher the number, the faster the video card. These 3 have Ti and Super versions, which have a higher clock speed than the regular versions. For example, the RTX 2080 Ti is a lot faster than the 2080.
