Socket LGA1151 What reviewers say Reviews find only modest gaming gains over recent Haswell processors, making it a weak upgrade for owners of a fast existing system. The newer platform and overclocking options are more attractive for a fresh build. Sample overclocking results differ, so a particular clock speed is not guaranteed.

Unlocked Yes
Cooler in the box No
Memory support Up to 64 GB; two channels; DDR4-1866/2133 or DDR3L-1333/1600 at 1.35 V; 34.1 GB/s maximum bandwidth; ECC not supported.
PCIe PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4. PC Gamer describes the Z170 platform's faster DMI 3.0 chipset link and expanded storage connectivity.
Process 14 nm; Skylake; 37.5 × 37.5 mm package; Intel lists a 64°C Tcase limit, which is a case-temperature specification rather than a junction-temperature limit.
Cooler Boxed processor includes no fan or heatsink. Requires a compatible Intel 100-series motherboard; the launch notice names the Z170 chipset for unlocked processors.
