Everyone loves a good rumour, right? Well this one is a doozy, so grab as much salt as you can before reading.
The CPU and GPU are built on the same package.
CPU: IBM PowerPC 7xx-based tri-core processor "Espresso" clocked at 1.24 GHz before the 3.0.0 update, 3.24 GHz after the 3.0.0 update. This is an evolution to the Broadway chip used in the Wii, is 64 bit and uses Power6 technote When IBM has said that Nintendo has licensed the Power7 tech from IBM, Nintendo is not using it for the Wii U, explaining its backwards compatibility.
GPU: AMD Radeon High Definition processor codenamed "Latte" with an eDRAM cache built onto the die clocked at 550 MHz before the 3.0.0 update, 800 MHz after the 3.0.0 update.
Those figures are — for want of a better word — insane. Pushing the clock speed of the CPU from 1.24 GHz to 3.24 GHz would be an incredible feat, and as a result many people are already pouring bucketfuls of scorn over this rumour.
However, there's no smoke without fire, and there's still a chance that Nintendo has upped the speed a little via the update — the increase in system performance since the update could be directly related to such a boost.
As soon as more concrete information hits the web we'll let you know, but for the time being, this just seems too fantastical to be true. What are your thoughts?
