Extreme Tech have posted their Dual CPU Shootout: Opteron versus Xeon!

We've been covering AMD's 64-bit x86-64 "Hammer" architecture for quite some time now and are intrigued by its combination of 32-bit compatibility and performance, as well as the promise of a 64-bit future for desktop PCs. AMD divides up their 64-bit world into the Opteron and Athlon64 lines.

The Opteron series is targeted at workstation and server use, while the Athlon64 products are aimed squarely at mainstream desktop PCs and notebooks. Most of our coverage revolved around single processor systems, including our examination of Opteron on the desktop and the Athlon64 line of PC processors. We've also looked at Athlon64 in the small form factor arena and the first shipping mobile Athlon64 notebook PC.
