Six-Core Coffee Lake Processor

The Intel Core i7-8700K is a desktop CPU built on the Coffee Lake architecture with six cores and twelve threads. It runs at a base frequency of 3.7 GHz and reaches a max turbo frequency of 4.7 GHz. An unlocked multiplier allows enthusiasts to push clocks further. The chip includes Intel UHD Graphics 630 for display output without a discrete card.

LGA 1151 Socket and 300-Series Chipset

This processor fits the LGA 1151 socket but requires an Intel 300-series motherboard for operation. It supports dual-channel DDR4 memory and provides sixteen PCI Express 3.0 lanes for graphics and storage. A thermal design power of 95W means a capable cooler must be sourced separately as none is included in the box.

Boxed Processor With Integrated Graphics

The retail package contains only the processor itself, so a cooling solution must be purchased independently. Integrated UHD Graphics 630 operates at a base frequency of 350 MHz and a max dynamic frequency of 1.2 GHz, enabling basic video output and light workloads. Virtualization technology and 64-bit instruction support are also present for compatible operating systems.

Questions about this item

What thermal limit appears first when all six cores run at 4.7 GHz?

The 95 W TDP is the ceiling the cooler must handle before the chip throttles.

How loud and hot does the boxed cooler get during an all-day compile?

No cooler is included; you must supply your own solution for the 95 W TDP.

Which motherboard and memory kit must I already own to install this CPU?

An Intel 300-series board with an LGA 1151 socket and DDR4 memory are required.
