The Benchmarks

The Benchmarks

We were given three systems to benchmark, one with the fastest Kentsfield (Core 2 Duo QX6800) and the other two with Penryn (one of which was a dual-core and the other, a quad-core). Here are the exact processors used for this test:-

  • Intel Core 2 Extreme Processor QX6800 (8MB L2, 2.93GHz, 1066MHz FSB)
  • Pre-production 45nm Penryn dual-core (6MB L2, 3.33GHz, 1333MHz FSB, codenamed Wolfdale)
  • Pre-production 45nm Penryn quad-core (12MB L2, 3.33GHz, 1333MHz FSB, codenamed Yorkfield)

The overall test systems' configuration are as below:-

  • Intel BadAxe 2 Desktop Board D975XBX2 (modified for Penryn)
  • ASUS NVIDIA GeForce 8800GTX
  • NVIDIA ForceWare 100.65 graphics driver
  • 2 x 1GB Corsair TWIN2X2048-8500C5 set to DDR2-800 5-5-5-15 in BIOS
  • Seagate Barracuda 7200.10 320GB
  • Antec TruePower Trio 650 power supply
  • Microsoft Windows Vista Ultimate (32-bit edition)

We tested the three systems with the following benchmarks:-

  • 3DMark06 Pro v1.1.0
  • Mainconcept H.264 encoder
  • Cinebench R9.5
  • Cinebench R10 (beta)
  • Half-Life 2 Lost Coast Built 2707
  • DivX 6.6 Alpha with VirtualDub 1.7.1
