Nintendo's latest Wii U firmware update has boosted the console's GPU and CPU speed, according to a new rumour.

The rumour comes from a poster on TV Tropes who hasn't cited any sort of source or provided any evidence, so please do treat this as rumour for now.

Their post reads:

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.

So following the 3.0.0 update, it is claimed that both the CPU and GPU have seen a clock speed increase.
