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??
This is stupid.
