The Intel
Core 2 Duo processor family is already well known for its overclocking
capabilities, but as Intel refines its manufacturing process, later generations
are showing improvement.
The Core 2 Duo E6750 has a default clock speed of
2.66GHz, and the particular CPU PCSTATS is testing is the new 'G0' stepping.
Going in to the overclocking challenge PCSTATS is anticipating a healthy 1GHz
overclock at the very least... maybe even more. The Core 2 Duo E6750
(Engineering Sample) CPU will be overclocked on a MSI P35 Platinum motherboard with a 2GB set of Corsair's
fantastically fast Twin2X2048-8888C4DF DDR2 memory.
Starting at 333 MHz FSB, the P35 Platinum's frequency was
increased in 5 MHz increments. It was clear right from the get go that the Intel
Core 2 Duo E6750 is a better overclocker than the E6600 CPU. With a slight
voltage bump, from 1.25V to 1.35V, the CPU easily passed 3.4 GHz. No matter what
we tried with the Core 2 Duo E6600, we could never get it running past
3.4GHz.
Continuing to overclock the Intel Core 2 Duo E6750
processor further, PCSTATS had to up the voltage to 1.4V to get the chip stable
at 3.6 GHz. The little processor was a wicked overclocker, and with 1.45V
reached a maximum speed of 3.8 GHz in our tests! Not bad considering we stuck
with a stock Intel heatsink!
I think one thing is pretty clear from these overclocking
tests, the Intel 'G0' stepping Core 2 Duo processors overclock very well. Even
if you don't have a super fancy heatsink and just a quick motherboard and pair
of memory you should be able to achieve some great overclocking results. That's
great news for everyone.
Considering how well the Intel Core 2 Duo E6750
overclocked here, you can bet PCSTATS will be putting this CPU under the Prometeia Mach II GT very soon. That's a tale for
another article, unless of course you don't want to see a CPU cooled to -35C
and overclocked?
Prelude to Benchmarks - Test
System Configuration
Over the following page we'll be running the
socket 775 Intel Core 2 Duo E6750 processor though PCSTATS standard set of
gaming, productivity, and 64-bit processor benchmarks. There are a wide variety
of gaming and synthetic benchmarks here to illustrate what kind of performance
boost users can expect from these latest, dual core 64-bit processor.
The specific details of how the Intel Core 2
Duo E6750 processor test systems were configured for benchmarking - including
the hardware, software drivers, operating system and benchmark versions - are
indicated below. In the third and fourth columns are the general specs for the
AMD and Intel reference platforms that the dual core Core 2 Duo E6750 is being compared against.
Please take a moment to look over PCSTATS test system
configurations before moving on to the individual benchmark results on the next
several pages.
