So How Powerful Are The New NVIDIA RTX GPUs? Real-Time Ray Tracing Explained

Nvidia has finally announced their new lineup of cards with the RTX 2080 Ti, RTX 2080 and RTX 2070 which is all part of the Turing family. They have gone with a new naming convention by switching to RTX instead of GTX which they have been using for almost a decade now. A lot of people might be curious as to why they changed the name to RTX for these cards and what the Ray Tracing hype is all about so let’s shed some light upon this.

Ray Tracing is a rendering technique that generates an image by tracing the path of light as pixels. It’s what movies and TV Shows use to create life-like scenes using CG work. Ray Tracing is a very intensive process which requires quite a bit of processing power which is why it was only really used in pre-rendered media where there were no real-time calculations. While lighting in games has improved a lot over the past few years, it still never really hit levels of photorealism due to the fact that it was never Real Time. What Ray Tracing on these GPUs will do is actually process things in Real Time, in game which will create lifelike shadows, lighting, reflections and, sub-surface scattering. Since it uses a lot of algorithms to do it, the hardware will have to be quite powerful to be able to pull it off in Real Time.

What does all this mean though, you ask? Using Ray Tracing technology in games, we can expect much better and realistic lighting and overall visual fidelity. Reflections will be much better with accurate colour reflections, translucency and transparency. This is a big jump in terms of technological advancements and video game graphics because over time this technology will become mainstream as more and more games and GPU manufacturers start using this technology which in turn means that games in the future will look even more beautiful and “real” as compared to right now before. This could very well be ushering in the new generation of computer graphics and I’m quite excited to see how this technology expands and grows over the coming few years.

If you want to see Ray Tracing being used in video games like Battlefield V, Shadow of the Tomb Raider and Metro Exodus, click here. For gaming right now, the RTX 2080 Ti, RTX 2080 and RTX 2070 are the only cards which completely support Ray Tracing.
