The Tech Report has taken a look at the Opteron 165 and Opteron 180 processors:
AMD'S OPTERON 100 SERIES processors have led a difficult existence. For most of their run, they've been sojourning in the wilderness of single-plug Socket 940 motherboards—a lonely and desolate place, to be sure. They've had to suffer in relative obscurity as their siblings and cousins, the Opteron 200 series and the Athlon 64, have gone on to resounding success. That's gotta damage a chip's psychological makeup. With the move to dual-core CPUs, though, the Opteron 100 series looks poised for success. After all, if you can get essentially two Opteron processors into a single-socket motherboard, you've got low-end server and workstation nirvana.
