Iray is a GPU-based rendering engine that is able to utilize multiple video cards to achieve maximum performance. In this article we will be testing to see how well Iray is able to use both different models of video cards as well as multiple physical cards in parallel.
The NVIDIA GeForce GTX 980 4GB is a very interesting card in that it really isn’t that much faster than the cards already available, but it has a dramatically lower power draw – 80W less than the GTX 780 or GTX 780Ti.
Recently, a question came up in one of our department meetings: are video cards getting more or less reliable? There are times when it feels like video cards are failing left and right and we start to pine for the “good old days”. Then, we remember how hot Fermi cards used to run. To get a more accurate answer this question, we decided to examine our GPU failure logs and break down the numbers by generation.
