The Z170 chipset has been available for some time now, but due to Intel's staggered launch of Skylake-S the other chipsets from this generation have just recently become available. In addition to the Z170 chipset, there are now five other consumer chipsets: the H170 and H110 for consumers and the B150, Q150, and Q170 for business.
With the move to the new Skylake-S CPUs, all of these chipsets have some large changes over their predecessors, such as the move the DDR4 and many other things we covered in our "Z170 vs Z97: What is the Difference?" article, but they also have a couple of key ways in which they differ from each other.
There are a large number of differences between the three consumer chipsets, but we have marked what should be the most important for the average consumer in red. The first and most commonly known difference is the fact that the Z170 chipset fully supports CPU overclocking, while the H-series chipsets do not.
