Wii U has a 3-core main processor that runs at just 1.2 GHz, according to a Wii hardware hacker.
We’ve heard before from developers that the Wii U CPU wasn’t as fast as they expected. Now according to Wii hacker “Marcan”, the exact clock speed of the Wii U CPU has been found.
Marcan posts via Twitter that the Wii U CPUis clocked at 1.2 GHz, with 3 cores based on the IBM PowerPC 750 design. The Xbox 360 and PlayStation 3 both use CPUs with clock speeds in the 3 GHz range, but the Wii U has a much more modern design and the processors can’t be compared clock-by-clock.
The Wii U GPU runs at 550 MHz, according to Marcan. While the main processor of the Wii U might not feature fast clock speeds, the GPU is certainly much more powerful and advanced than the Xbox 360 and PS3 counterparts.
Marcan also revealed some of the codenames Nintendo uses for the internal hardware: the Wii U system is called “Cafe”, the CPU is “Espresso”, and the GPU is “Latte”.
Nintendo will probably reveal the official console specs at some point in the future, either directly or a developer will leak the spec sheet like they did with the original Wii. Until then, the Wii U specs remain only rumors.
