Skylake would be built around a totally new 14 nm process design as an update over the Tri – gate architecture. Instead of featuring the Gen 8 GPU, Skylake would feature the latest Gen 9 integrated HD graphics along with the being the first main – stream platform to get Dual channel DDR 4 memory functionality. That being said, Haswell – E ( successor to the IVY BRIDGE – E ) and Skylake would be the only two desktop platforms with native support for DDR 4 memory from Intel and would ditch the much older DDR 3 memory support. Intel were not keen on reporting whether or not DDR 3 memory RAM would be compatible with these line – ups of processors so it seems only time holds the answer to one of the main core questions. Besides having compatibility with DDR 4 memory, Skylake would also feature PCIe 4.0 functionality which theoretically doubles the bandwidth over PCIe 3.0.
