The Wii U specification details has finally arrived, According to development source close to Eurogamer, Wii U will be powered by CPU which features three IBM Power PC Cores, an AMD series 7 GPU and 1GB of memory available to games.
The clock speed of Wii U CPU is not revealed, but reports suggest that it will be lowered than that of Xbox 360 and PS3. According to the source, 1GB of RAM will be available for the game in Wii U, this is twice than that of Xbox 360.
The GPU is a custom AMD 7 series, supporting shader type 4 and DX10 type features, with embedded eDRAM.
Here is what Eurogamers Source said:
"Wii U has a powerful GPU with more oomph than the rivals – and is more modern in architecture and shader support, which may come in handy later on."
"The CPU on the other hand is a different question. We are not limited by it but some other games might suffer from it. Still, because of the GPU, I expect most multi-platform games to look the best on Wii U, even if the difference might not be huge sometimes."
