I agree, I have a used HP workstation that has two X5450, and I can smoke the i7-6700k hands down any day., on its turbo mode the i7 would still fall behind., above all the i7 wasn't built to run on full speed non-stop for months like the xeon.
i notice they like to fudge the specs in order to convince you to buy the way way more expensive intel core i7-6700k cpu, like how they use the absolute lowest tdp when they compare your cpu to the one they want you to buy!. they show the x5450 as a 55c tdp when its really 55c to 75c tdp. getting to where i dont even bother to look at the specs they post because of the bias any more!. even tho its 2017 the i7 is still well above 300 dollars where as the x5450's can be had for a mere 20 bucks on ebay. add to that you can get a dual socket mobo for these chips for around 60 bucks, and the memory is dirt cheap now so that you can put together a nice powered system for less than you will pay for the i7 cpu!. and i love how they always compare what you are looking for, to the lastest intel cpu no matter what it is you are looking for!. they must be getting some kind of kickback, to be pushing intel as hard as they do!.
