Apparently the chip scores over 400 000 instructions/second in SiSoft Sandra's integer test and about 300 000 instructions/second in a floating point test.
The quad-core Intel QX6800 only scores about 300 000 it/s in integer and about 180 000 it/s in the floating point test.
So at least in multimedia stuff and this synthetic benchmark AMD's native quad core is 33.3 percent faster than Intel's fastest Quad core, while in the floating calculations it is a massive 66 percent faster.
The QX6850 with FSB 1333 might improve the situation a bit, but it won't be enough save the day. Intel needs to go much higher than 3 GHZ to match the 2.5 GHz K10 part.
