[citation][nom]CaedenV[/nom]apples and oranges.The WiiU's GPU is part of an ecosystem built to optomize performance for any titles that will play on it. HD4000 is meant as an iGPU to provide adequate performance for most applications and needs the flexibility to run Windows XP->8, OSX, as well as Android.HD4000 is mostly geared for 2D workloads, and only entry level 3D workloads. WiiU is aimed at minimal 2D workloads and moderate 3D workloads.HD4000 shares system memory and resources with the rest of the computer, while the WiiU GPU is a dedicated GPU with its own memory, bus bandwidth, and resources.Simply put: The WiiU would smoke the HD4000, as well as most other iGPUs like AMD's APU designs, because it is in a different league entirely, and built for a different use case than iGPUs are. that does not mean it is 'good' or 'bad' compared to other systems, it is simply adequate for what the designers at Nintendo need to have games look and act the way they are supposed to. Compare it to a $50 dedicated GPU and then you are talking about something closer to an apples-apples comparison.[/citation]
Unless it is better than a 4870 or 4890, the WiiU isn't likely to be able to beat AMD's upcoming Kaveri APU (supposed to have a rough equivalent of a Radeon 7750 for its IGP). Furthermore, it wouldn't smoke AMD's APUs for the same reasons for why it may smoke Intel's CPUs in IGP performance. AMD's APUs have gaming GPUs. Low end, yes, but gaming nonetheless.
