EuroGamer: How Powerful is the WiiU Really?

[M.U.G.E.N]

"How powerful is the Wii U really? Is it less powerful than the PS3 and Xbox 360? Is it as powerful? More powerful? And how will it compare to the next generation? What quality of graphics will we see from Wii U games?

Answering these questions is impossible, given how abstract the idea of console power is in the first place. Is X twice as powerful as Y? Is Y 10 times as powerful than Z? And what does power mean anyway?

And yet, we want answers. Part of what makes us love games is what makes them look so good. Advancements in graphics technology have defined the game industry as new hardware comes and goes. Graphics, for so many, mean so much."

 

"The CPU: The Wii U's IBM-made CPU is made up of three Power PC cores. We've been unable to ascertain the clock speed of the CPU (more on this later), but we know out of order execution is supported.

RAM in the final retail unit: 1GB of RAM is available to games.

GPU: The Wii U's graphics processing unit is a custom AMD 7 series GPU. Clock speed and pipelines were not disclosed, but we do know it supports DirectX 10 and shader 4 type features. We also know that eDRAM is embedded in the GPU custom chip in a similar way to the Wii."

We asked Blitz Games Studios' design director John Nash the impossible to answer question: is the Wii U more powerful than the current generation? "It's comparable to the current generation and a bit more powerful than that," he replied. Pretty unscientific, eh?

First, the positives. Where the Wii U outdoes the current generation is in RAM and GPU. The Wii U has, effectively, twice the RAM available to games that the Xbox 360 and the PS3 each have. And we hear much praise of the GPU.

"The Wii U is a nice console to work with because it's got so much RAM in comparison [to the PS3 and Xbox 360]," another Wii U developer, who wished to remain anonymous, told us. "For E3 we simply dumped the whole game into memory and never once used the disc after the content was loaded from it."

It is the RAM in combination with the GPU that means Wii U games have the potential to outshine Xbox 360 and PS3 games. Indeed, according to one source, the Wii U version of his company's game will be "the smoothest console version".

"We're a GPU-heavy game," the source continued. "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."

The mention of the Wii U's CPU raised our eyebrow - as it has done for many developers we've spoken to. While its clock speed remains private, most developers agree it is lower than the clock speed offered by the PS3 and Xbox 360's CPUs - disappointing for many.
