When we nicknamed Intel's new dual-core Xeon processor "Hot Carl," we didn't know how prophetic this would be. A fresh set of benchmarks comparing the Xeon with AMD's dual-core Opteron chip show Intel's product to be a power hungry demon that doesn't perform.
GamePC got its hands on some of the Xeons - code-named "Paxville" - and put the chips through a battery of tests. Most startling is the dual-core Xeon's voracious power consumption. Intel reckons Paxville will need 135W for average software loads and run up to 150W at peak. When plugged into a two-way server, this pull proves troubling.
"There's no doubt about it, Intel's dual-core Xeons are their most power hungry Xeons to date," GamePC writes. "Even when idling, two dual-core Xeons consume nearly 400W of power at any given time, which is amazingly high, even by Intel's standards.
"AMD's competing dual-core Opteron processors consume far less power, especially using AMD's PowerNow! Technology. When this is enabled, Opteron power consumption drops to roughly 160 to170W when idling. "To be fair, we could not get EIST to function with our new dual-core Xeons, which may help idle power consumption levels. However, their full-load levels are ghastly high."
