Comparing Intel Dual-Core and Quad-Core Using VMmark

Friday, 20 July 2007 by Michel Roth

Bruce Herndon has been testing VMmark on a variety of systems in preparation for the benchmark's imminent release. He has measured the performance difference between Intel's dual-core (Woodcrest) and quad-core (Clovertown) processors:

"I have been running VMmark on a wide variety of systems in preparation for the benchmark's imminent release. During this exercise, I was able to measure the performance difference between Intel's dual-core (Woodcrest) and quad-core (Clovertown) processors using otherwise identical HP Proliant DL380G5 systems. One system contained two dual-core Intel Xeon 5150 processors (four cores total) running at 2.66 GHz. The other system contained two quad-core Intel Xeon 5355 processors (eight cores total) running at 2.66 GHz. Each system contained 32GB of memory and was connected to the same VM library hosted on an EMC CX-300 storage array. Both systems were running ESX Server 3.0.1. "
