If I understand the workings of the 'CPU' correctly, today's rumour of the Broadway cores also don't make sense because of clock speed.
Devs have said that the clock speed of the WiiU's processor was relatively low, but if it were still of Broadway architecture wouldn't it need massive clock speed to actually pack a punch nowadays?
If I'm wrong (my knowledge is limited as my interest in hardware decreased since like the early Pentium 4 days) people are allowed to call me a dumbass .
