Core i5-6402P for LGA 1151 desktop builds

The Intel Core i5-6402P is a quad-core desktop processor for the LGA 1151 socket. It targets builders who need a 65 W chip without integrated graphics dependencies for discrete GPU systems. The Skylake architecture delivers four threads at a 2.8 GHz base clock. Retail packaging includes the processor and stock cooler.

6 MB L3 cache and dual-channel DDR4 or DDR3L support

Four cores share 6 MB of L3 cache and 4 x 256 KB L2 cache for predictable throughput. Memory controllers run dual-channel DDR4-1866 or DDR4-2133 as well as DDR3L-1333 or DDR3L-1600 at 1.35 V. Turbo Boost lifts single-core speed to 3.4 GHz when thermal headroom allows. Heavy multi-threaded workloads saturate the four threads quickly.

Intel HD Graphics 510 and retail cooler in the box

The integrated Intel HD Graphics 510 drives up to three displays for troubleshooting or basic desktop use. A stock cooler rated for the 65 W TDP ships in the retail box, so no separate purchase is required for standard operation. Virtualization technology is enabled for hypervisor workloads. The 14 nm process keeps power draw modest.

Questions about this item

Will the i5-6402P fit into my existing LGA 1151 motherboard without a BIOS update?

The processor uses the LGA 1151 socket; compatibility depends on the motherboard chipset and BIOS version, so check the board maker's CPU support list before installing.

How can I verify the Intel HD Graphics 510 is active after I install the CPU?

Connect a display to the motherboard video output, enter BIOS to ensure integrated graphics are enabled, then confirm the 510 appears in Windows Device Manager under display adapters.

Does the BX80662I56402P retail box include a cooler, or must I buy one separately?

The retail package ships with Intel's stock cooler attached, so no separate purchase is required for standard 65 W operation.
