CPU World said:[...] Skylake "Y" processors will retain "Core M" branding, that was introduced last month, and will have 2 Hyper-Threaded CPU cores and GT2 graphics. One SKU will have 4 MB L3 cache and Vpro features, whereas several other chips will come with smaller 3MB L3 cache, and they will lack Vpro. All Core M parts will support Turbo Boost technology.
"U" series will utilize familiar Core, Pentium and Celeron branding. The SoCs are going to have 2 CPU cores, and will be available with 15 Watt and 28 Watt TDP. Core i5 and Core i7 15 Watt models will incorporate 3 MB and 4 MB L3 cache respectively. Both i5 and i7 chips will integrate GT2 or GT3e GPU, and support Hyper-Threading and Turbo Boost technologies. Some SKUs will have Vpro features enabled. The only graphics option on Core i5s, rated at 28 Watt TDP, will be GT3e. Core i7s 28W chips will have GT3 graphics unit only. Standard features on Core i3 15 Watt microprocessors will be GT2 graphics and 3MB cache, while the GPU on Core i3 28W parts will be upgraded to GT3e. Pentium and Celeron processors will not support Hyper-Threading, their GPU will be dowgraded to GT1, and the size of L3 cache will be reduced to 2MB.
Core i5 and i7 "H" CPUs is going to have 4 cores and 45 Watt Thermal Design Power. Some models will support configurable TDP of 35 Watt. Some SKUs will also have Vpro feature available. New in Skylake "H" series will be Core i3 dual-core processor or processors. They will have GT2 GPU and 35 Watt TDP.

Skylake-Y, ''Core-M'' (4W TDP): 2C/4T+GT2
Skylake-U Celeron/Pentium/Core (15W TDP):
- Core i3: dual-core, GT2 graphics
- Core i5/i7: 2C/4T, GT2 or GT3e graphics
Skylake-U (28W TDP):
- Core i3: dual-core+GT3e graphics
- Core i5: 2C/4T+GT3e
- Core i7: 2C/4T+GT3(e?)
Skylake-H (45W TDP, cTDP 35W selected models):
- Core i5/i7: quad-cores
- Core i3 (35W TDP): dual-cores+GT2 graphics
GT3e will finally make its way to 15W ''U'' chips and GT4e will likely be introduced in 47-57W models. Late 2015/2016 Macbook Air could pack Iris Pro and a Retina screen.
