Intel Woodcrest, AMD Opteron and Sun UltraSparc T1 - Server CPU Shoot-out

@ 2006/06/09
Intel's new Xeon wipes the floor here with the competition. Up to 75% faster than the 2.4 GHz Opteron, the new Xeon won't have any trouble with a 3 GHz Opteron. We have to investigate this further, but it seems that this is the result of massive 4 MB L2 cache and intrinsically better integer performance of Woodcrest. Additional tuning might push the T1 higher, but we are pretty sure it is not going to be a screamer in this benchmark.

interesting thoughts on Dual Core CPUs too in there

The Intel P-M architecture went from 1.7 GHz Single Core (Banias) in 2003 to 3 GHz (Conroe, Woodcrest) in 2006, while it quadrupled the L2 cache and significantly improved the IPC. At the same time, AMD's K8 series went from 1.8 GHz to 2.8 GHz dual-core, with the same amount of cache, and almost equal IPC. The result is that AMD will not be able to regain the performance crown in the dual and quad-core market until the K8L arrives.
