Depending on the yield / voltage requirements expect roughly 350 USD for a 4.K running up-to a K for roughly 430 USD. This small company offers pre-tested and binned processors, at reasonable prices as well. Today we test a Core i7 4790K has we have obtained from Mind you that we purchased a processor, this is not a review sample. The process of selecting (in this case) processors based on performance, that is binning. Getting that best GPU or processor in your hands is like winning a lottery, a silicon lottery. You all have seen this with graphics cards, some overclock way better, others not so much. to decide which product range the chips fit best in. Overall chip manufacturers test and sort chips based on various criteria such as leakage current, power draw at key frequencies, salvageable defects, etc. These differences all fall with a certain threshold, however once you start to overclock you will pass that ‘acceptable’ threshold and will seek a performance level that can differ due to the aforementioned reasons. So to continue on the last chapter of the previous page, that means that even within the same batch of wafers, there will be minor differences.
