Intel Z170 Skylake will be available soon and at the moment there aren't more details about ASRock motherboards. During last Computex we have done few pics of some motherboards but since they are not the final product some detail could change.
Z170 Gaming K4Checking on PCB and according to
TPU, the Gaming K4 and H170 Performance share a common PCB design. This motherboard is designed for who wants a simple gaming rig but with some good features like dual bios chips, 4-pin pwm headers, 2x Sata Express (above the PCH) and M.2 Slot.
Z170 Fatal1ty Gaming-ITX/ACAccording to the
specs picture always from Computex, this model features 8 power phase design and supports up to DDR4 3400+ (OC). On PCB we find 1x Sata Express, 6x Sata, 1x Ultra M.2 x4 and 2x USB 3.1 Type-C. That is a very good amount of features for a small ITX motheboard.
Z170 Extreme 7The Extreme 7, like the name suggest, should be one of the top model. This card offers 12 power phase design with 4x PCIe 3.0 x16, 1x PCIe 3.0 x1, 1x PCIe 2.0 x1 and 1x Mini-PCIe. Thanks to the good amount of PCIe on this Extreme 7 you can do 3-way CFX and Nvidia Quad SLI. Regarding the storage we have spotted 3x Ultra M.2 slots (!), 3x Sata Express, 10x Sata3, 2x USB 3.1 (Type-A and Type-C).
This is only a small preview of motherboard displayed in last Computex 2015; I'm sure that there will be more series and models. Actually on Z97 there are 3 series: Gaming, Extreme and Overclocking.
