Nvidia RTX is a more recent line of graphics cards that were introduced in 2019 with the 20 series.
RTX is a marketing abbreviation, meaning “Ray Tracing Texel eXtreme”, and, as the name implies, these cards were the first to introduce some dedicated ray tracing capabilities.
Ray tracing is a rendering technique that simulates the way light interacts with objects in a 3D environment. This allows for more realistic lighting, shadows, and reflections, which can be used to create incredibly realistic visuals. Nvidia RTX cards are the first to have dedicated hardware for ray tracing, allowing for more efficient and accurate ray tracing than ever before.
So why is it called RTX instead of GTX? Well, Nvidia has been using the GTX branding for its high-end graphics cards for years, and RTX is a new branding that is meant to signify the new ray tracing capabilities. By calling it RTX, Nvidia is emphasizing the fact that these cards are the first to have dedicated ray tracing hardware, and that they are a step up from the GTX cards.
The RTX cards also have some other features that make them stand out from the GTX cards. They have faster memory, better cooling, and improved power efficiency. All of these features make the RTX cards more powerful and capable than the GTX cards, and this is why Nvidia chose to call them RTX instead of GTX.
In conclusion, Nvidia RTX cards are the first to have dedicated ray tracing hardware, and this is why they are called RTX instead of GTX. The RTX cards also have some other features that make them stand out from the GTX cards, such as faster memory, better cooling, and improved power efficiency.
