Test Setup:

We used a new Intel motherboard for these tests, and while it may not be the fastest board around it is one of the few boards that work with Conroe CPUs.  The board on the bench is the Intel DG965WH board and it features the brand-new G965 chipset.  This chipset features the new Intel GMA X3000 DirectX 10 GPU and has some nifty features in itself.  For the tests in this article we are not using the integrated video, but instead an eVGA 7600GT CO as well as the other hardware listed below.

  • Intel Pentium 805 Smithfield Processor
  • Intel Core 2 Duo E6600 Processor
  • Intel DG965WH Motherboard
  • 2GB 2x1GB Crucial Ballistix PC8000 (DDR2-1000) - Crucial
  • Plextor PX-750A DVDRW Drive - Plextor
  • Seagate 250GB SATA II 7200.9 HDD
  • eVGA 7600GT 256MB
  • Windows XP Professional with all available updates
  • Intel Chipset Drivers
  • ForceWare 91.31 drivers.

Hardware Info:

Thankfully Intel's Core 2 Duo is based on the same Socket as their previous processors.  However, not every board that can fit an LGA775 processor can run a Core 2 Duo.  In fact, there are only a few chipsets that officially support this processor.  One such chipset is the 965 series from Intel.  We were lucky enough to score a motherboard as well as a processor and have had quite a bit of fun with this combination.  Below are pictures of the Conroe Processor and our test bench motherboard.

To keep the platform equal between processors, we clocked everything at default speeds and ran our Crucial PC2-8000 at DDR800 with 4-4-4-10 timings.  The DG965WH doesn't support a 1066MHz memory speed, so we chose 800MHz with tighter timings.  Other than changing up the CPU, nothing changed throughout testing.  The performance difference that we will see in a few minutes is directly related to CPU performance, and perhaps a bit better bandwidth management in the memory subsystem on the Core 2 Duo.
