Just for fun we changed the bus speed from 333MHz to 400MHz and the system was stable and solid.

Reviews Word on the street for the Intel Core2 Duo E8500

Just for grins, we'll also toss in performance numbers of an Intel Core 2 E8500 dual core CPU, which also costs around $300.

It's also impressively efficient compared to the outgoing 65nm generation of Core 2 Duo CPUs from Intel.

What People Are Saying Give it to me straight

Socket Type

At launch a little over 18 months ago, the X6850 was the world's fastest PC chip and cost a cool £600.
by Tech Radar (May, 2008)
If you consider that the original Pentium processor, which ran at 66MHz (and that was the high-end model), was built using an 800nm process, with a measly 3.1 million transistors—well, you get the idea.
by PCMag (Jun, 2008)
By increasing the FSB to 400MHz we could now run the DDR3 memory at 1600MHz versus the previous speed of 1333MHz.

The numbers here show a ~1.24x gain from E6750 (CNR 2.66) to E8500 (WFD 3.16), which comes partly from the frequency gain (~19%) and partly from the architecture gain.
by Legit Reviews (Feb, 2008)
With a die size of just 107mm2 and 410 million transistors, it is smaller than its predecessor, the Conroe, as it had a die size of 143mm2 with 291 million transistors.

The XFX GeForce 8800 GTS 512MB used NVIDIA ForceWare 169.28 video card drivers and the ASUS P5E3 motherboard using BIOS version 1001, which was the most recent available when testing was done.

Results: POV-Ray Real-Time Raytracing is a great benchmark that we love to use on Legit Reviews and it does a great job at showing how performance scales with CPU cores.
by Legit Reviews (Feb, 2008)
It's also significantly quicker in every benchmark than the X6850.
by Tech Radar (May, 2008)
The Intel Core 2 Duo E8500 that we specifically looked at in this article did very well in the benchmarks and consistently beat the AMD Phenom 9600 Black Edition quad-core processor.
by Legit Reviews (Feb, 2008)


It's worth putting all this in perspective before we dive into the performance numbers of these two quad-core CPUs in our showdown today.
by PCMag (Jun, 2008)
This goes to show how well the Wolfdale core has been developed and also how bad of a position AMD is in when it comes to processors.
by Legit Reviews (Feb, 2008)
It's also true that for under $300, you can buy an Intel quad-core CPU manufactured on a 45 nanometer (nm) process.

Microsoft Office Excel 2007 is a powerful and widely used tool with which you can create and format spreadsheets and analyze and share information to make more informed decisions.

The input file is a 70.1 MB spreadsheet and with 10 times the calculations of the first test, this one should take a bit longer to complete.

On a two-CPU system, the rendering speed in some scenes almost doubles.
