Intel Core 2 Duo E6750 2.66 GHz 1333MHz FSB Processor Review
Intel Core 2 Duo E6750 2.66 GHz 1333MHz FSB Processor Review - PCSTATS
If you haven't already heard, Intel recently injected fresh life into its Core 2 Duo Conroe platform by increasing the front side bus speed from 1066 MHz to 1333 MHz.

Core 2 Duo Performance-Per-Watt Metrics

Gone are the days when performance benchmarks settled all Intel vs. AMD processor debates. With increased awareness of our Carbon footprints, it is equally important to choose computer hardware that consumes as little electricity as possible. Energy efficiency is in, and if electrical bills don't motivate you then reduced heat output and quieter cooling system will certainly make your head turn.

Perhaps it's only when we consider the 24x7x365 electrical operating cost of a computer that any reduction in power consumption musters attention, but there it is. In a sense, what's happening now parallels the transition from loud computers to the silent PC esthetic. Before hot-running computer processors went quiet, enthusiasts' attempts to reduce the PC noise were exceptions to the rule, rather than the norm.

An entire industry now thrives on selling quiet computer hardware, and the same is beginning to happen with energy efficient desktop processors, power supplies and even hard drives. PCSTATS is pleased to see the computer industry moving forward in a positive energy efficiency direction. Bonus points to anyone in the crowd reading this who has an 80+ certified in their PC right now, you're leading the way.

Energy efficient components is certainly a new aspect PCSTATS will be considering as we mull over the benchmark results for the Intel Core 2 Duo E6750 processor. Now, let's start off with total system power draw tests.

Core 2 Duo E6750 Total System Power Consumption Tests

The cost of energy is increasing world wide, so any reduction in the amount of power a CPU requires is welcome. Wading through the technical numbers to figure out the differences can be confusing because Intel and AMD report power values in slightly different ways.

AMD reports maximum power consumption while Intel posts typical values. Obviously the two wattage figures are not comparable and to find out which actually consumes more power, we have to test things out.

Representing Intel will be a Core 2 Duo E6600, Pentium D 940, Pentium D 840, and Pentium 4 540 processor. Standing in for AMD are the socket AM2 Athlon64 X2 4800+, Sempron 3600+, Athlon64 FX-62, Athlon64 X2 5000+, and socket 939 Athlon64 4000+ and Athlon64 FX-60 processor.

The test specs for each system are kept as constant as possible: Akasa PowerPlus AK-P550FF power supply, Western Digital 74GB Raptor hard drive, an 8x Gigabyte DVD-/+RW drive and a MSI NX6600GT-TD128E videocard.

Cool 'n' Quiet is disabled for these tests because with Cool 'n' Quiet enabled, total system power draw will be even less that what is reported. A picture of the total system power draw test configuration is shown at right. The Extech Power Analyzer is located between the mains 120AC supply and the PC's power supply.

PCSTATS uses an Extech model 380803 Power Analyzer Datalogger for measuring CPU power & total system power draw.

The tool can be found here if you would like to replicate these microprocessor power measurements yourself. The test setup is illustrated above, but obviously with different hardware than the E6750 was tested with.

To simulate single-core load, the Prime95 Small FFTs test was run, and two instances launched for dual core loading. Total system power consumption was read with the Extech Power Analyzer Datalogger (model 380803) for both CPU loaded and CPU idle states. These wattage values are measuring an entire system while the processor is running under computational load or idle.

Those power draw test results are next...
