Due to its specifications, the Core i7-6950X taken from the Core i7-5960X the title of most high-end desktop CPU available, mostly because of the 20 threads. Its price also reinforces this title. By the way, it is interesting to notice that, by now, Intel always priced their flagship CPU around USD 1000, but now the second model (Core i7-6900K) is around this price and the highest-end model costs almost twice.
But is it the fastest desktop CPU available today? Depends on your use. Its score on CineBench R15 states that, in 3D rendering tasks, it is unbeatable. Our tests also show that it is excellent for video editing, since the software you will use is ready for using 20 threads simultaneously. Actually, on any task where the 20 threads are fully used, the Core i7-6950X will beat any desktop processor.
Our tests indicated that, besides being faster than the Core i7-5960X because it has 25% more cores, Intel also worked well at the architecture optimization and the performance per thread also was increased. So, in tasks that use all the cores, the performance gain of the Core i7-6950X can be higher than 30% when compared to the Core i7-5960X.
But for the typical user? And for the gamer who wants to build a gaming computer? In this case, the conclusion is the same we found on the Core i7-5960X: it is not a good deal, since it is much more expensive than a mainstream CPU and will not present a performance gain that justifies it. For most users (including heavy users) the Core i7-6700K, for example (which is a high-end CPU from LGA1151 platform) costs five times less and will probably perform almost the same way on games or common tasks. And, with the money saved, you can buy a better video card, memories, or a high-end SSD, for example.
The Core i7-6950X can be the most high-end desktop processor available today, but thanks to its elevated price, it only worth for professional applications like 3D rendering or video editing, where the performance gain can raise productivity.
