| Never said: One of the more interesting things about the wii u hardware is how it offloads the os onto a dual core 1 gig arm processor so not to hog resources. |
The OS of the Wii U doesn't hog resources? The OS has a footprint of 50% of the RAM! Only half of the 2 GB RAM are available for games.
The 360 had an OS-footprint of 6% (32 MB of 512 MB), the bloated OS-footprint of the PS3 is reduced to 10% (50 MB of 512 MB) since 2009: http://community.eu.playstation.com/t5/PS3-General/PS3-OS-memory-footprint-slashed/td-p/9874872
So... does the Wii U switch off the main processor outside off a game to save power consumption (idling in the main menu, eShop, internet browser, netflix...) and only uses the ARM processor? Obviously not... besides standby the WiiU always takes the same amount of power, no matter if a game is running or if it idles: 28 - 33 watt
