Paxville is only 50% of Opterpn performance

When compared to contemporary Opterons, the "Paxville" Xeon posts the highest numbers on only one benchmark: the power consumption one. As tested by GamePC, Intel's latest consumes roughly 400 watts of power at idle, and pushes nearly 430 watts at full load. The numbers are so horribly out of whack that the fastest Opteron--the 2.4GHz Opteron 280--consumes 56% less power than the slowest Xeon. Heat output for the Xeon is rated at a peak of 150 watts, well in excess of the sub-100 watt TDP designs of the Opteron dual-core chips.

This voracious appetite for power and prodigious production of heat would be excusable in a high-performance environment if it outperformed the Opteron competition, but that appears to be the main thing the Xeon cannot do. After testing the Xeon and Opteron with SiSoft Sandra 2005, 3D Studio Max 7.0, Maya 6.5, WME 9.0, LAME MT, Apache Bench, and ScienceMark 2.0, the results showed that the Xeon was soundly defeated in every single benchmark. In some cases, the margin of Opteron victory was double the score of the Xeon.....

As a further downside, the dual-core Xeons will not work with any existing Socket-604 motherboard, meaning customers with existing Xeon investments must start from scratch.

Dell has announced it has full confidence in this new Xeon and is shipping servers based on it immediately.
