It took some time for the developers (games, rendering, and other productivity) to fully utilize the Ray Tracing capabilities of the RTX graphics cards. With a 75% performance to the previous GTX 1080 GPU and dedicated Ray Tracing cores in the GPU, the RTX 2080 was a revolution in the graphics world. In late 2018, Nvidia released RTX 2080, the first graphics card to support ray tracing. The concept of ray tracing is very old but the “hardware” to implement this in real-time started with Nvidia’s RTX Series of GPUs. Ray Tracing is an advanced technique for modeling optical effects such as shadows, reflections, refractions, light scattering, and many more. Here, the important term is “Ray Tracing”. RTX stands for Ray Tracing Texel Extreme. With the technology continuously evolving, Nvidia moved on from the GTX technology to the much superior RTX Technology, starting with the RTX 20 Series of Graphics Cards. Some popular GTX Graphics Cards from the recent past are: All these cards essentially contain an upgraded version of the GTX technology. Coming to GTX stuff from Nvidia, you might remember the GTX 1080, GTX 1070, and even the most recent GTX 1650 and GTX 1660. The “software” that does this job is the Shader.Įnough technical blabber. Shading is the process of calculating the amount of light, color, and darkness while rendering a 3D image. ![]() But the GTX (sometimes GTS) series had a huge improvement in the geometric shading process. In the world of digital computing, special graphics processing units or GPUs do the job of mapping the texels to pixels and producing a 3D image.īefore GTX, Nvidia had similar technology and called it GT (Giga Texel), GTS (Giga Texel Shader), and others. Similarly, a Texel is the fundamental element of a Texture Map, which is the image applied to the surface of a polygon in graphic design. We know a pixel is the smallest element of an image. Here, two terms “Texel” and “Shader” are very important. Nvidia has been making graphics cards forever but it started the “GTX” branding only in 2008 when it launched the GeForce GTX 260 and GTX 280 Graphics Cards.
