Iray is able to utilize multiple video cards to decrease render times, but not everyone needs (or has the budget for) the absolute fastest rendering machine with four GPUs. While physically small, this compact workstation is still able to fit two full-sized video cards which can provide a significant performance advantage over single GPU systems. Iray scales very well with multiple cards, which means that by using two cards instead of one, your render times will complete much faster!
While the GPU is the most critical factor when using the Iray rendering engine, the CPU options on this system are able to operate at up to 4.5GHz when only using a single core. This means that even though you will be getting terrific rendering performance, this system will also work well when creating and editing models in Maya, 3ds Max, Cinema 4D, or other supported applications.
