A new road-map from Intel surfaced on the web with the Kaby lake refresh processors, these were called Kaby Lake-H. The new Kaby Lake Refresh models however will be called the Core ix 8000 series and would supposedly be the mobile quad core parts with separated chipset.

The refresh processors will be released roughly in week 33 of 2017 reports Benchlife. The difference in-between the U and H series is based upon the used platform. The U series will be a multi-chip package, ther H series should get the processor soldered onto the PCB socket (BGA). Current Skylake-H processors have 4 cores running roughly 2 GHz with up-to 3 Ghz turbos and have a 25 Watt TDP. 

 
The table also shows information on coffee lake, the quad-core procs would get a GT2 GPU and the hexa-core parts a GT3e GPU. You'll also spot the mention of Socket R in the table, we're quite convinced that is for Coffee Lake-X processors, if you look upwards on that chart.

All these procs will be listed in the Core ix 8000 range of products.

Intel cancels Kaby Lake-H - Kaby Lake Refresh will be Core ix 8000 series
