Earlier this year we updated our CPU buying guide putting Ryzen front and center, and while that guide is due for an update now that Ryzen 3 and Threadripper have landed, those picks are still as valid today as they were back then with the Ryzen 5 1600...

Going into this review, we suspected Kaby Lake-X wouldn't be anything too impressive, mostly because these quad-core CPUs have no place on a high-end desktop platform that they can't fully drive. The fact that they provide weaker performance and greater power consumption than the original Kaby Lake processors only adds insult to injury.

So I think most people will admit that AMD has had a lot of wins this year with all of the Ryzen launches. As I found out in our 1700v7700K coverage the 7700K was still a great performing CPU, especially when looking at gaming performance. But with...

Intel allows high-end desktops to achieve much higher performances by introducing Skylake-X and Kaby Lake-X. This is certainly good news for content creators, who could use the higher performance for 3D-rendering, video editing or other demanding, creative workloads. Nevertheless there are some ifs and buts before we can start cheering, which takes us to a famous old movie.

Warum existiert der Intel Core i5-7640X überhaupt? Der Vierkerner leistet bei weitem nicht so viel wie teurere Kollegen auf Enthusiasten-Mainboards. Dank der vergleichsweise hohen Taktfrequenzen ist die CPU aber bei Single-Core-Anwendungen recht stark....
