Skylake is the codename for a processor

Central processing unit

The central processing unit is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in...

Microarchitecture

In computer engineering, microarchitecture , also called computer organization, is the way a given instruction set architecture is implemented on a processor. A given ISA may be implemented with different microarchitectures. Implementations might vary due to different goals of a given design or...

 to be developed by Intel as the successor to the Haswell architecture. Skylake will use a 14 nm process.

As of 2011 there are no official details regarding this microarchitecture's development, however in light of news that the mainstream Haswell platform will feature quad-core processors it is expected that Skylake will introduce the first Intel CPUs with 8 cores to mainstream platforms.

In keeping with Intel's tick-tock

Intel Tick-Tock

"Tick-Tock" is a model, of Jones Farm 5 and adopted by chip manufacturer Intel Corporation since 2007 to follow every microarchitectural change with shrinking of the process technology. Every "tick" is a shrinking of process technology of the previous microarchitecture and every "tock" is a new...

principle, the 10 nm shrink of Skylake is due out the year after the introduction of the microarchitecture and will be codenamed Skymont.
