For each point on the screen, it shoots out a ray from the camera to that point, then tries to determine its color/value. Physically based renderers, such as Iray, tries to approximate the physics of reality. It may receive light from outside, there may be shadows cast from nearby objects, and there may be indirect lighting from nearby surfaces. Any single point can receive light from an infinite number of directions. Therefore, the best way to evaluate which farm is the right one for you is experience both iRender and Xesktop, test some frames/scenes and decide by yourself.We do not normally think about it, but real-world lighting is very complex. The rendering time will vary in projects with different assests, settings, etc. Note: The test result is only for the reference because it is a quite simple test scene. Artists choose which render farm according to their needs, for who only care about the speed, iRender is perfect while Xesktop is more preferred for who want to optimize the cost. However, the price of Xesktop is more reasonable: $6/hour for 10x GTX 1080Ti, $8/hour for 8x Tesla V100, compared to the lowest $3.8/hour to the highest $28/hour of iRender servers.

Overall, iRender ranks 1 in terms of rendering speed.

3 remaining servers of iRender (1x RTX 3090, 2x RTX 3090 and 4x RTX 3090), on the other hand, are slower than both Xesktop servers. They both are faster than Xesktop’s fastest server – 8x Tesla V100.

As we can see from the results, server 6x RTX 3090 and 8x RTX 3090 of iRender have the shortest time to render.
