We start off with a couple of benchmarks that mainly measure CPU performance. In the graphs you can see two motherboard 'categories', which are caused by the enhanced turbo that some manufacturers set. This means that the turbo speed, that should only be for one core according to Intel, is used for all cores. This is basically some kind of overclock. All X299-motherboards allow you to turn this enhanced turbo on or off. This means that the performance is not a factor on which you should base your motherboard choice in our opinion. For all of the other things they do not vary all that much.
