Intel Core i7-6850K socket: LGA 2011-v3

What the Core i7-6850K is

The Core i7-6850K brings Broadwell-E to LGA 2011-v3 for multi GPU rigs with DDR4. It launched in May 2016 with a 3.6 GHz base and up to 3.8 GHz boost at 140 W. Intel targets gamers and creators who need six fast cores with full lanes.

Fifteen megabytes of Smart Cache carry games and timelines. The high base clock keeps frame rates steady. Twelve threads cover play plus streaming and capture.

There is no integrated GPU, so a discrete card is required. The process is 14 nm. The multiplier is unlocked. DDR4-2400 and 2133 in four channels feed cores with up to 128 GB.

Buyers add cooling because no cooler ships in the box. The 140 W rating needs a tower or liquid unit. Turbo Boost Max 3.0 lifts favored cores for single threads.

Socket and motherboard compatibility

The Core i7-6850K fits LGA 2011-v3 on X99 boards with DDR4 slots. Makers list Broadwell-E with 2016 BIOS builds. Early stock may need an update.

Haswell-E shares the socket but predates Broadwell-E microcode. LGA 2011 and LGA 2066 cannot take this chip. The Socket vs chipset: what decides whether a CPU works guide covers matching.

Single socket HEDT towers are the case. Another LGA 2011-v3 chip can follow on the same board where listed. Power needs solid rails for 140 W plus graphics.

Memory, PCIe and cooling

DDR4-2400 in four channels up to 128 GB covers gaming plus creation. Quad channel bandwidth helps renders. Start with 32 GB for mixed rigs.

PCIe 3.0 with 40 lanes from the CPU allows three graphics cards plus NVMe per X99 layout. The 6800K trims to 28 lanes where budgets are tight. Chipset lanes add SATA and USB.

Cooling follows the 80 by 80 mm pattern in the CPU cooler compatibility by socket guide. A 140 W tower or 240 mm liquid unit holds boost. No cooler ships in the box.

Upgrade paths

On the same socket, the Intel Core i7-6800K drops to 3.4 GHz base with 28 lanes for lower cost rigs. The Intel Core i7-6900K moves to eight cores for faster renders. Both share X99 boards.

Mainstream i7-6700K gives fewer cores with graphics for pure gaming. It needs a different board.

Past HEDT moves to Skylake-X on LGA 2066. The i7-6850K covers 2016 rigs where six fast cores with full lanes must deploy.
