What is V-Ray Tracing in RTX GPU – RTX 3050/3070/3080

Before I begin about talking V-Ray Tracing you have to know Ray Tracing is actually working. So here we begin:

What is Ray Tracing?

Ray Tracing is a method or technique that can produce realistic lighting effects with their algorithm can trace paths of light and make graphics realistic, and then simulate the way that the light interacts with the virtual objects it ultimately hits in the computer-generated world.

Ray tracing allows to create dramatically more lifelike shadows and reflections, along with much-improved translucence and scattering. The algorithm takes into account where the light hits and calculates the interaction and interplay much like the human eye would process real light, shadows, and reflections, for example. The way light hits objects in the world also affects which colors you see.

V-Ray Tracing

Due to limited TGP in laptop,  the RTX 3070 laptop GPU appears to lag behind the desktop-grade RTX 3060 Ti and RTX 3070 models.

First look at the RTX 3070 laptop GPU performance comes through the V-Ray 5 website that now supports a series of tests specifically designed for Nvidia’s RT cores included with the previous gen Turing and current gen Ampere cards. The RTX 3070 laptop GPU scores 1394 points, but we also see results for some desktop-grade Turing and Amepre cards. Compared to an RTX 3070 desktop GPU, the laptop version appears to be ~30% slower, but this is to be expected since the laptop GPU is based on an inferior SKU. A fairer comparison would be with the RTX 3060 Ti desktop GPU that is rumored to be based on the same SKU as the 3070 mobile. In this case, we see a difference of only ~7% in favor of the desktop version. These differences may actually prove to be lower in gaming loads, as V-Ray is only testing ray tracing performance without rasterization.
