PCH - The Platform Controller Hub Chipsets

With the Kaby Lake generation desktop processors comes yet again a new motherboard chipset. You can stick to the Series 100 Chipset from Intel but a Series 200 is released as well. For end consumers like you and me the H270 chipset will be less performance targeted and comes with better support for HTPC monitor connectivity. The Z270 chipset however is targeted at mainstream performance and enthusiast end users allowing much more tweaking and providing performance features.  
  

 
The 200-series chipset tied to the processor series is tagged under the codename "Union Point," and will support Intel Optane SSDs and Rapid Storage Technology support for PCIe storage devices. Desktop processors based on Kaby will use LGA 1151, the Skylake slot, and support TDPs from 35, 65 and 91W. The last model will obviously be an unlocked K series processor. The Kaby Lake platform for desktops will support USB 3.1 and DDR4, the laptop versions however will have to make do with USB 3.0 and DDR3. For Kaby Lake you do not need a new motherboard, if you already have an H or Z170 series chipset, upgrade your motherboard BIOS and you should be fine with the new processors.

The X270 chipset will have a few more PCI-Express gen 3.0 lanes. The Processir will deliver 16, the chipset has been bumped from 20 (Z170) towards 24 for Z270. The processor and chipset are connected thourgh the DMI interface which Intel kept at 3.0, and that this is a x4 lane link.
