What the Core i7-4702MQ is
Intel Core i7-4702MQ is a quad core Haswell M series part that Intel released in May 2013 for serviceable laptops with socketed boards. It uses the Haswell core design on a 22 nm process, running at 2.2 GHz base with turbo to 3.2 GHz. The cache is 6 MB Smart Cache. Power is 37 W. Graphics come from Intel HD Graphics 4600 (400 MHz to 1150 MHz).
The cores carry Hyper-Threading for 8 threads. The GT2 graphics block with HD Graphics 4600 covers office work and video without a separate chip, while gaming bodies pair a discrete GPU over PCIe. The package supports DDR3L SODIMM memory that can be serviced.
At 37 W the Core i7-4702MQ belongs to the M series socketed group. The 2.2 GHz base with 3.2 GHz turbo suits everyday multitasking with a single fan. Laptops pair it with SODIMM memory and SATA SSDs. The How to find your CPU socket type guide shows how to confirm the socket before ordering parts.
Socket and motherboard compatibility
The Core i7-4702MQ fits Socket G3, a 946-contact pin grid array with socketed rPGA packaging. The socket also accepts Haswell M, MQ and MX parts, but BIOS support still decides each model. Check the laptop service manual for access steps and the maker CPU support list for the exact model string.
Power and firmware decide service results. The 37 W envelope sizes the heat pipes and fans, and the board BIOS must list the exact Core i7-4702MQ string. HM87 and HM86 boards pair the mobile SKUs, while QM87 covers workstation bodies. The CPU cooler compatibility by socket guide notes socketed laptop parts use board specific heatsinks.
Memory, PCIe and cooling
Memory support is ddr3l-1333 and 1600, two channels, up to 32 gb. Two SODIMM slots allow service and upgrades to the board maximum. Two matched modules help the graphics block that shares system RAM.
PCI Express is PCIe 3.0 with 16 lanes from the CPU. Boards wire lanes to discrete graphics options, Wi-Fi and SSDs. A mainstream card of the era pairs without waste where the chassis allows.
Cooling uses board specific heat pipes and fans sized for 37 W. Repaste and fan cleaning help sustained turbo more than any setting change.
Upgrade paths
A same socket move on Socket G3 is possible in theory but narrow in practice. The Core i7-4702MQ can swap for another G3 part where the manual allows access and the BIOS lists the target, for example to a Core i7 MQ part with more cores. The heatsink and power envelope must match.
A platform move means a new laptop. Current Intel mobile lives on newer BGA packages with DDR4 or LPDDR4 and current wireless, which no Socket G3 board can reach. Recycle the old laptop through a proper e waste path once data is wiped.
Frequently asked questions
What socket does the Intel Core i7-4702MQ use?
It uses Socket G3, a 946-contact socketed rPGA package.
Can the Core i7-4702MQ be replaced?
