It's Not All About CPU
"Here we are, nine years later, and Sun's "Niagara" family of Sparc T servers are not competitive with the most recent x64 boxes."
Sun's processors have never been competive with Intel/AMD CPUs. However the systems have had consistently better IO, threading and reliability than most x86 systems. If the CMT chips are so uncompetitive, why the continued increase in volume sales of the T series boxes during the 25+% drop in other systems over the past few quarters?
And how come Sun got to 54%, by volume, of UNIX server shipments a couple of quarters back, according to Gartner? This could only be due to shipments of the cheaper T series systems as they were behind IBM and HP on revenues.
