I understand that you are comparing performance of the processor when the processor is over-clocked by you.
Keep in mind that Intel provide the unlocked processors, so the customer can over-clock it under his / her own risk, and Intel does not guarantee any performance or stability while the processor is running above it is stock speed.
I personally suggest running the processor at it is stock speed with the turbo bust enabled, allowing the processor to over-clock automatically when the operating system determines that it is required to, but this way the processor will be running under specifications.
That is not the question I am asking. As you can see above, the stock nonoverclocked settings are shown above and for some reason is underperforming on the Sisoft Dhrystone Wheystone tests. The stock settings produce a 65/35 score consistantly. The stock turbo setting for 4 cores is 3.4Ghz. Many review sites and others produce 85/48. This is a 30% decrease in performance on the dhrystone test alone. My o/c settings are only to show that even overclocked to 4Ghz, it only reaches 73/42.
