ASRock sent me their X299 Taichi motherboard and after several tests I can say that it is a great product. I would start with the excellent look, and those 2 cog wheels that give the impression they are alive and moving.

The performance is good, but Taichi doesn?™t raise all the CPU cores to Max Turbo 3.0 frequency, like other boards. Yet, the overclocking is on par with other competitors, even if ASRock board has only one 8-pin connector.

The price is excellent, so it is a great choice for gaming rig on LGA2066 platform.

So the other manufactures seem to be using the Multi-Core Enhancement feature with Turbo 3.0. Note that Turbo 3.0 is NOT the standard Turbo 2.0 feature.

Turbo 3.0 is a feature first used with Intel socket 2011-v3 processors, with X99 boards. Turbo 3.0 selects ONE processor core over the others to be used for the maximum Turbo frequency, which it determines is the best core to be used. The Multi-Core enhancement feature, used with Z170 and Z270 chipset boards (including ASRock), runs all the cores at the maximum Turbo 2.0 frequency, which is a type of built in OC feature. The other manufactures have it enabled by default.

That difference in the core speeds of the other boards is a big difference, and not an equivalent comparison. That would easily account for at least some of the differences in performance, if not all of the difference. At least the review mentioned that factor in the conclusion, but if you only look at the graphs, you miss it. ASRock could easily add the same feature to their X299 boards.

As the old saying goes, the devil is in the details, and this is a perfect example of that. I found this detail simply scanning the review for a few minutes. If we don't read the entire review, we really didn't read it.
