This test is so unscientific it's basically worthless. No reason to even bother paying attention to these results.
IF the 2014 models are slower, they're still fast enough that 99.9% of customers will never notice a difference and the other .01% will never be happy.
Wait a sec... are you seriously telling us that your scientific argument would be that "yes, the speed tests proved that the speed dropped by half (in certain cases), but who cares"?! WTF!
