AMD dominates the Java server performance hill
This Shanghai Quad Core Opteron server from HP scores 1,181,782. The best Intel Nahelem based Xeon X5570 scores about 542,793, less than 50% of AMD.
Core i7 has shown some good IPC numbers, but it is no big iron like Opteron, which scales to 8P 32 core. This again shows that Intel is a desktop company which only knows how to do 2P, while AMD's Opteron is a server chip designed by server people.
It's rumored that AMD will yank Intel's AMD64 and Direct Connect licenses.
PS: I see one reader tries to multiply Intel's score by 4, as if Intel can pile up 4 Nehalem servers to compete against 1 Opteron server. But 1000 sheep can't beat a single wolf. The math does not add.
