On who has a "faster" machine etc here is a post that is interesting from inquierer.net
""SO IBM hypersters are claiming their cell chip can do two teraflops per second. what about the lastest power5??? Go to IBM.com and find out here.
There you can see the latest and fastest power5 dual core processors can do 56.78 Gigaflop/sec in an eight way configuration. That's 16 Power5 cores combined, and the total is only 56.78 gigaflops for 16 lowly Power5 cores, or, about three gigaflops/per core. which makes sense, a float point operation takes more than one clock to finish, and each power5 core has probably two or more FP units...
So, there is no magic, you can't possibly do more than one instruction in one clock in one unit. You can do multiple if you have multiple units. To have 1000gigaflops, you will need 500 units each operate at two gigaflops.
A teraflop means 1000 gigaflops, so IBM is claiming that one PS3 is 2000% faster than an eight way power5 server selling at half a million bucks??"
Many people like to throw around things like PS3 is 2x more powerfull then X360 or the reverse X360 with the architecture will keep up with PS3 and not have to use the raw processing power that the PS3 architure will require. There are alot of geek facts in the background that make these statments very hard to qualify. Both systems are going to rock we do know that. The current Xbox is more powerfull then the PS2 there is not much argument about that, though the graphics are better on Xbox the games that are out for the systems are still the selling points for most, so who has the more "powerfull" system will, IMHO, not be a selling factor to most as it is assumed on message boards.
Sorry about the spelling... working on another project right now....
