The Wii U’s CPU is slower than those inside both the PlayStation 3 and the Xbox 360, according to a Tecmo Koei developer.

Warriors Orochi 3 Hyper producer Akihiro Suzuki admitted to Eurogamer at the Tokyo Game Show that the Wii U version of his game had a lower frame-rate and fewer on-screen enemies as a result.

"One of the weaknesses of the Wii U compared to PS3 and Xbox 360 is the CPU power is a little bit less," he said.

"So for games in the Warriors series, including Dynasty Warriors and Warriors Orochi, when you have a lot of enemies coming at you at once, the performance tends to be affected because of the CPU.

"Dealing with that is a challenge."

The exact specs of the Wii U’s reportedly-underpowered CPU are unknown at this stage, but the console’s custom AMD 7 series GPU apparently fares much better.

Its 1GB of RAM available to games is double that of the PS3 and Xbox 360, and allowed the Orochi development team to create visuals that surpassed those of the PlayStation 3 and Xbox 360, said Suzuki.

"From a visual standpoint, based on the performance of the Wii U, we knew the game had the capability of having much better graphics than games on PS3 and Xbox 360. Make no mistake; from a visual standpoint, it is able to produce better graphics."

"While the visuals are great, as is being able to improve them, we had to deal with the lower CPU power and how we can get around that issue," he said.

"Actually, we're still working on that. If you see the demo on the show floor and you try it, you'll probably feel it's not up to the PS3 level. But we're working on it!"
