System Specs & Memory Performance

Hardware
- Intel Core 2 Extreme QX6700 (2.66GHz)
- Intel Core 2 Extreme X6800 (2.93GHz)
- Intel Core 2 Duo E6700 (2.66GHz)
- Intel Pentium D 950 (3.40GHz)

- 2GB Corsair XMS DDR2-800 (CAS4)

- ASUS P5W DH Deluxe (Intel 975X)

- OCZ GameXStream (700 watt)

- Seagate 250GB 7200RPM (Serial ATA II)

- Gigabyte Radeon X1900XTX (512MB)

Software
- Microsoft Windows XP Pro 32bit (SP2)
- ATI Catalyst (6.10)
- Intel System Drivers (7.2.2)

The memory performance of the QX6700 is much the same as that of the E6700. Both processors are operating at 2.66GHz using a 1066MHz quad-pumped FSB, so the similarities in memory performance are not all that surprising. In fact, all four configurations delivered similar memory performance and all four used the same DDR2-800 memory.

You should get used to this scenario where the Core 2 Extreme X6800 shows a slight performance edge because the tests take better advantage of higher clock frequencies than the extra cores.
