Opteron and Barton compared at 1.4GHz

HardwareMania has put together a quick comparison of AMD's 1.4GHz Opteron running on an nForce3 Pro150 versus a Barton-core Athlon XP at 1.4GHz running on an nForce2. Both systems used PC2100 memory under Windows XP SP1, which isn't 64-bit. Despite the fact that the Opteron is running in 32-bit compatibility mode, its clock-for-clock performance is still quite impressive. The nForce3 Pro150 doesn't look too shabby, either, though I do wish it had PCI-X support.
