Desktop chips based on Skylake are available already, but the enthusiast level about Core i7 6600K & 6700K went on sale on August. Later this month the non K desktop ships containing Core i5 & i7 will launch. Even though we in start thought the ‘S’ variant of Skylake would be the first available desktop chip, the unlocked K series released first for desktop PCs.

Specialties

One of the reasons to buy a PC with a Skylake chip is the sheer number of new characteristics it’ll bring. Intel says the chips have the biggest PC innovations for the last 10 years. Instead of being a simple functioning bump, Skylake will bring support for DDR4 memory and usher in so-called wireless computing. The Core i7 chips have 16 PCI Express 3.0 lanes for graphics which can be split into 1x 16-lane, 2x 8-lane or 1x 8-lane and 2x 4-lane channels.

The memory controller supports dual-channel DDR4 or DDR3L DRAM, and they use the Socket 1151. The H170 chipset will replace the H97 for mainstream PCs, while the H110 will be the ‘value’ offering, replacing the H81 and various other chipsets.

Verdict

The K versions of Skylake are multiplier unlocked. Interestingly, the base clock is separate from the PCI-E bus. This means you can adjust the core clock frequency of the chip without affecting anything else.
