Intel 14-nanometer Skylake Platform To Support DDR4, PCIe 4.0, SATA Express@ 2013/07/04
Additionally, the new mainstream platform will bring in support for PCI-E 4.0, essentially doubling the bandwidth offered by the current PCI-E 3.0 standard. More powerful GPUs from NVIDIA and AMD should be able to take advantage of the improved bandwidth, as their cards keep getting more and more powerful with each passing generation. Skylake will also introduce support for SATA Express. The advantage? SATA Express allows for a max bandwidth of about 16 GB/s, more than 2.5x the 6 GB/s bandwidth offered by the current SATA standard. While the product slide doesn't specify exactly as to when the first Skylake based products are scheduled to hit the market, our best guess places it at the end of 2015.
