What the Core i7-8086K is
The Core i7-8086K celebrates 40 years of x86 with an unlocked 5.0 GHz boost. It launched in the second quarter of 2018 with a 4.0 GHz base and up to 5.0 GHz boost at 95 W. Intel bins it above 8700K for enthusiasts who want guaranteed single thread peaks.
Twelve megabytes of Smart Cache feed gaming threads. The very high 4.0 GHz base sustains frame rates without waiting for boost. Twelve threads cover streaming helpers beside play.
UHD Graphics 630 from 350 MHz to 1200 MHz with device ID 0x3E92 handle displays when discrete cards idle. The process is 14 nm and the multiplier is unlocked for tuning. DDR4-2666 in two channels with up to 128 GB suits gaming towers. Technical City lists DDR3 plus DDR4 support, while Intel lists DDR4-2666, and this page uses Intel.
Socket and motherboard compatibility
The 8086K fits LGA 1151 on revision 2 boards only. Z370 and Z390 enthusiast boards pair it with strong power stages for 5.0 GHz bursts. Early boards may need a BIOS update for anniversary IDs. Revision 1 never accepts it.
DDR4-2666 in two channels up to 128 GB covers gaming with fast kits. Dual channel operation lifts minimum frame rates. The Socket vs chipset: what decides whether a CPU works guide explains enthusiast board matching.
Single socket gaming towers are the home. Another unlocked 300 series chip on the same board changes the tuning headroom.
Memory, PCIe and cooling
DDR4-2666 in two channels up to 128 GB with fast SSDs gives responsive gaming. Start with 16 GB of low latency kits. Bandwidth near 41.6 GB per sec feeds six cores.
Sixteen Gen3 lanes in 1x16, 2x8 and 1x8 plus 2x4 splits hold a high end GPU plus NVMe. Most anniversary builds pair strong graphics for 144 Hz play. Chipset lanes add the rest of storage.
95 W unlocked cooling needs a capable tower or liquid loop for sustained 5.0 GHz. The 75 mm LGA 1151 pattern from the CPU cooler compatibility by socket guide applies with even pressure.
Upgrade paths
On the same socket, the Core i7-8700K gives similar threads with slightly lower boost at the same 95 W where listed. The Intel Core i7-8700T trims to 35 W at lower clocks for small cases. Both share 300 series boards.
Pentium anniversary parts suit collectors with fewer cores. They lack threads for modern multitasking.
Past LGA 1151 anniversary builds move to newer unlocked generations. The 8086K covers collectors and gamers where 5.0 GHz must endure. The $425 launch price from Technical City is aggregator data without Intel RCP context, so no price row is included.
