Intel’s Skylake will feature a new 14nm CPU, PCIe 4.0, SATA Express, and DDR4

Path to Skylake

The future is coming in 2015 and Intel has a lot in store for enthusiasts. Intel’s next microarchitecture will be at a 14nm processing node, feature a new architecture, and boost some exciting new technologies. First, Intel is going to bring PCIe 4.0 support which will have double the bandwidth of PCIe 3.0 (16GB/s to 32GB/s or 1GB/s per lane to 2GB/s per lane). Next, DDR4 is going to make its debut to consumers with Haswell-E, but when Skylake rolls around, DDR4 prices will be more reasonable, and the technology will be more mature. DDR4 will provide more bandwidth, is more power efficient (operates at a lower voltage), and supports higher capacities per DIMM.

In addition, Intel will also provide support for a new version of AVX (Advanced Vector Extensions). Finally, SATA express will bring the bandwidth of PCIe to SSDs. Currently, SATA 3 is already being saturated and is a real bottleneck for SSDs. SATA express aims to remedy this issue by providing up to 16GB/s bandwidth, which is obtained by utilizing the PCIe bus. So, if you are already on Sandy/Ivy it may be worth while to skip Broadwell, which is a 14nm die shink of Haswell, and wait for Skylake in the first half of 2015.
