Sorry, but the 360 is not more than 512bits, maybe even 256!
Therefore the one is only 1024 bits, at most!
I'm a bit expert, I have done a lot of research on the subject, you should not post mis-information on the forum, less technically inclined people could take you seriously.
That numbering scheme makes no sense whatsoever, how do you know about each console's bit power?
When I started asking for an NES my grand-mother took this abomination out of an old closet and said, there you go, video games for you! That thing didn't even have colors! Unfortunately I had been introduced to gaming before and I wasn't impressed at all.
