TG Daily has an analysis on Dell's decision to launch servers with AMD Opteron processors:
AMD's Opteron processors will make their premiere in Dell's high-end, multiprocessor servers, it was announced yesterday during Dell's quarterly earnings report. We don't know the specific Opteron models, nor do we know yet how Dell will brand its AMD-powered units, or how it will price them. There's a good chance these details have yet to be worked out. TG Daily has contacted high-level representatives from both Dell and AMD for comment, which may yet come today.
