Intel Core i7-10700K socket: LGA 1200

What the Core i7-10700K is

The Core i7-10700K is an eight core, sixteen thread processor from Intel's 10th Gen family, codenamed Comet Lake. It was announced in April 2020 as the unlocked middle model between the Core i9-10900K and the Core i5-10600K. It is built on Intel's 14 nm process, like the generations before it, and shares the Skylake based core design with them.

The base clock is 3.8 GHz. A single core can reach 5.0 GHz through standard turbo and 5.1 GHz with Turbo Boost Max 3.0, which targets the best core on the chip. The 16 MB L3 cache is shared. Intel lists a 125 W base power, with a lower 95 W configuration at 3.5 GHz that some boards expose.

The chip includes Intel UHD Graphics 630, so a display can run without a graphics card. Intel also sold the Core i7-10700KF, which is the same processor without integrated graphics. Intel does not include a cooler in the box with any K-series processor, so you have to budget for one.

Socket and motherboard compatibility

The Core i7-10700K goes into an LGA 1200 socket. Every LGA 1200 board accepts it, because Comet Lake is the original generation for the socket. That covers the 400 series (Z490, H470, B460, H410, Q470, W480) and the 500 series (Z590, H570, B560, H510, Q570, W580). No BIOS update is normally required.

To use the unlocked multiplier you need a Z490 or Z590 board. On the other chipsets the processor runs at its rated speeds, and some boards still allow memory tuning. A board with weak power delivery can hold the chip below its full turbo clock, so reviews of the specific board are worth reading before buying.

Processors for LGA 1151 do not fit, even though the package looks identical. The notch is in a different place. For the opposite direction, Rocket Lake chips of the 11th Gen work on 500 series boards, and on 400 series boards with Z490, H470, Q470 or W480 chipsets after a BIOS update.

Memory, PCIe and cooling

The memory controller supports DDR4 only, with an official limit of DDR4-2933 for this model. Faster modules run at their rated XMP speed on boards that allow it. Intel lists support for up to 128 GB across two channels, and the chip does not support ECC memory.

PCIe lanes from the processor run at version 3.0, with 16 lanes for graphics. That is the main difference to the 11th Gen Rocket Lake chips, which brought PCIe 4.0 to the same socket. Boards for this chip often provide more PCIe lanes through the chipset for storage and extra slots.

LGA 1200 keeps the 75 mm cooler mounting pattern used since LGA 1156. A cooler from an LGA 1151, 1150 or 1155 build will normally fit. Because the 10700K draws up to 125 W and more in short bursts, pair it with a tower air cooler or a liquid cooler rather than a basic one. The CPU cooler compatibility by socket guide lists the patterns.

Upgrade paths

Staying on the socket, the next step is an 11th Gen Rocket Lake processor, which needs a 500 series board or a compatible 400 series board and brings PCIe 4.0 on supported boards. The top of the range there has eight cores, so the core count does not rise compared with the 10700K.

A bigger jump needs a new platform. LGA 1700 boards, such as the ones for the Intel Core i5-12400F, use different processors and a different cooler pattern, and they can take DDR5.
