In an article on the differences in the various Skylake chipsets, Matt Bach at Puget Systems writes:
In addition to having fewer and slower PCIe lanes, H110 also still uses the older DMI 2.0 revision which means the connection between the chipset and the CPU is a bit slower than it is on the other chipsets.
The accompanying table lists Z170, H170, and B150 all as DMI3 (8GT/S) and H110 as DMI2 (5GT/S).
What is the practical significance of this? Would an H110 board always run slower than the other boards noted above? Should you avoid an H110 board if you want the best performance?
