At the end of August Intel introduced the Haswell E processors and we published a comparative test of 15 Intel X99 motherboards. Since our last test we have received another few new motherboards and we have retested some boards that did not perform optimally in our original test. In this update we introduce the new boards on the market and show the updated test results of all 20 motherboards.
We will not repeat everything that we have already published in this update. If you want to know everything about the X99 chipset please read our original review. Should you not have done so, it is also worthwhile to check out our extensive review on the Intel Core i7 5960X / 5930K en 5820K Haswell-E processors.
In this review we look at five motherboards that were not in our original test. ASUS sent us their entry model X99-A, the slightly higher positioned X99-Pro and the workstation motherboard X99-E WS. ASRock shipped the X99 Extreme 6 and the gaming focussed X99X Killer, as you can see a bit further on in this review these two boards are virtually identical.
In our original review we noticed that especially the Gigabyte motherboards offered very poor performance. The BIOS developers at Gigabyte have been very busy it seems as most problems look like they have been solved. Gigabyte sent us three new samples of these boards and we have retested the X99-UD4, X99-UD5 and the X99-Gaming 5.

As in part 1 of our X99 roundup we do not go into detail on every motherboard that we have tested, but focus on the most important features of the new chipset that are implemented on the respective motherboards. As usual you can find our testresults at the end of the review, including several benchmarks, power use and a onboard sound test.
