The following are some initial tests of V-Ray RT running inside 3ds Max 2011 with a GPU/OpenCL render server. Disclaimer: these are just tests and should not be taken as final results.
Machine: HP Pavilion Elite e9180f workstation
CPU: One single Intel Core i7-920 processor (4 physical cores, 8 logical) at 2.67 GHz with 9 GB of RAM
GPU: One single nVidia GeForce GTX 480 graphics card with 1.5 GB VRAM, OpenCL used for rendering
Not shown on this page, but worth mentioning: V-Ray RT on GPU supports the same interactive scene adjustments as the CPU version, including camera movement, movement/deformation of geometry, light and material adjustments and so on.
The scenes are from Evermotion, ArchInteriors vol. 9; the Sponza Atrium and Sibenik Cathedral scenes are by Marko Dabrovic. The scenes are intentionally chosen to represent complex lighting conditions. The illumination comes from VRaySun and VRaySky; material effects include textures, glossy reflections, refractions and bump mapping.
In each case, the CPU/GPU versions were left to render for approximately the same amount of time. This includes the initial setup time required to transfer the scene to the render server application.
