A rumour is currently circulating the internet which suggests that the recent Wii U system update has actually increased the console’s GPU and CPU speed. This latest rumour comes from a poster on a fairly unknown site called TV Tropes. He claims that the clock speeds have been increased, but sadly he hasn’t cited any sort of source or provided any evidence. You can read his assessment, below.
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.
