Nintendo centric developers Shin’en claim that the Wii U GPU is actually several generations ahead of the Xbox 360 and the PlayStation 3. The development studio believes that developers need to harness the systems strengths to get the most out the system and concluded by saying that the Wii U specifications ultimately fit perfectly together and make a very efficient console when used right.
“The Wii U GPU is several generations ahead of the current gen. It allows many things that were not possible on consoles before. If you develop for Wii U you have to take advantage of these possibilities, otherwise your performance is of course limited. Also your engine layout needs to be different. You need to take advantage of the large shared memory of the Wii U, the huge and very fast EDRAM section and the big CPU caches in the cores. Especially the workings of the CPU caches are very important to master. Otherwise you can lose a magnitude of power for cache relevant parts of your code. In the end the Wii U specs fit perfectly together and make a very efficient console when used right.”
