How we configured our test systems: When configuring our test systems for this article, we first entered their respective system BIOS and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set memory timings for DDR2-800 with 4,4,4,12 timings. The hard drives were then formatted, and Windows XP Professional (SP2) was installed. When the Windows installation was complete, we installed the drivers necessary for our components, and removed Windows Messenger from the system. Auto-Updating and System Restore were then disabled and we set up a 1024MB permanent page file on the same partition as the Windows installation. Lastly, we set Windows XP's Visual Effects to "best performance," installed all of our benchmarking software, defragged the hard drives, and ran all of the tests.

Preliminary Testing with SiSoft SANDRA XI

Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA XI, the System ANalyzer, Diagnostic and Reporting Assistant. We ran six of the built-in subsystem tests that partially comprise the SANDRA XI suite with the Core 2 Duo E6750 ( CPU Arithmetic, Multimedia, Multi-Core Efficiency, Memory, Cache, and Memory Latency) . All of the scores reported below were taken with the processor running at its default clock speed of 2.6GHz.

Core 2 Duo E6750 @ 2.6GHz CPU Arithmetic	Core 2 Duo E6750 @ 2.6GHz MultiMedia	Core 2 Duo E6750 @ 2.6GHz Multi-Core Efficiency
Core 2 Duo E6750 @ 2.6GHz Memory Bandwidth	Core 2 Duo E6750 @ 2.6GHz Cache and Memory	Core 2 Duo E6750 @ 2.6GHz Memory Latency

The results reported by the various SANDRA test modules we ran fell right in line with our expectations. Considering the fact that the E6750 is clocked at the same speed as the E6700, their performances were quite similar according to SANDRA. The additional bandwidth afforded by the E6750's higher clocked FSB give it a slight edge in a couple of the tests, but where its advantage is most apparent is in the Memory Bandwidth benchmark. In the Memory Bandwidth test, the E6750 / P35 / DDR2 combo hit 6.3GB/s, whereas an E6700 / P965 / DDR2 combo typically hovers in the 5.6GB/s range. Somewhat surprisingly, the Cache and Memory and Memory Latency tests, the E6750 doesn't fare all that well against the E6700.

Marco Chiappetta

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
