I was under the impression that Broadway was further behind the 360 CPU than that. My mistake, I guess. (Out of curiosity, about how big is the gap? Would 5 or 6 un-enhanced Broadways rival the 360 CPU?) But if this was true, it would mean that, power aside, the fundamental design of the Wii U CPU (or each core, at least) would be unchanged since the Gamecube CPU was built in 1999. |
Nah, it's way behind. Broadway doesn't support the same instructions, its architeture is way less refined, it lacks logical cores, the extra vector units etc.
The Broadway is some 32 times slower than the Xenos on raw number crunching. Three Broadway cores would need to be clocked at something like 12 GHz to be comparable to the Xenos.
Just so you can compare the Broadway architecture was introduced (in an even less refined way, but still) in 1997 while the Xenos comes from the same Cell architecture IBM released in 2006, nine years later, an eternity as far as computer hardware is concerned so far.
