Intel Core i7-4700EQ socket: BGA 1364

What the Core i7-4700EQ is

Intel Core i7-4700EQ is a quad core Haswell embedded part that Intel released in May 2013 for carriers with long lifecycles. It uses the Haswell GT2 design on a 22 nm process, running at 2.4 GHz base with turbo to 3.4 GHz. The cache is 6 MB Smart Cache. Power is 47 W. Graphics come from Intel HD Graphics 4600 (400 MHz to 1000 MHz).

The four cores carry Hyper-Threading for 8 threads. The GT2 graphics block covers console output and signage playback without a separate chip. The package integrates the dual channel memory controller with ECC support and 16 PCIe 3.0 lanes on die. ECC matters for carriers that run for months without reboot.

At 47 W the Core i7-4700EQ belongs to the Haswell EQ embedded group. The 2.4 GHz base with 3.4 GHz turbo suits control, imaging and signage loads with directed airflow. Carriers pair it with DDR3L and SATA storage. The How to find your CPU socket type guide shows how to confirm the package before ordering parts.

Socket and motherboard compatibility

The Core i7-4700EQ solders to BGA 1364 with 1,364 balls in a 37.5 by 32 mm footprint and cannot be moved to another board. Embedded carriers qualify each EQ model with a specific board and BIOS for a locked lifecycle, so even another EQ part is not a drop in swap. Boards follow COM Express and Qseven formats.

Lifecycle and firmware decide embedded builds more than raw speed. The board BIOS must list the exact Core i7-4700EQ string with ECC support. The CPU cooler compatibility by socket guide notes that soldered embedded parts have no desktop mount pattern. Socket vs chipset: what decides whether a CPU works covers Intel pairing basics.

Memory, PCIe and cooling

Memory support is ddr3l-1333 and 1600, two channels, up to 32 gb, ecc. ECC catches single bit errors in long running tasks, which is the main reason to pick EQ parts over mobile twins. Capacity reaches 32 GB where the carrier allows.

PCI Express is PCIe 3.0 with 16 lanes from the CPU. Embedded carriers wire lanes to NICs, fieldbus, mini PCIe and mSATA rather than graphics slots. Display outputs follow the carrier wiring, so the maker manual is the final word on ports.

Cooling uses the carrier heatsink or spreader sized for 47 W. The industrial temperature range needs validation with the enclosure, not just the chip rating. Repaste helps only where the carrier design permits service.

Upgrade paths

There is no CPU upgrade path on soldered BGA 1364. The Core i7-4700EQ cannot be removed, so a faster EQ part means a new carrier. Within the family Intel Core i7-4850EQ shows another EQ option on the same package, but carriers and firmware rarely mix.

A platform move means a new embedded carrier. Current Intel embedded lives on newer BGA packages with DDR4 and current OS support, which no BGA 1364 carrier can reach. Storage and wireless age with the carrier as well, so a whole box replacement usually beats a carrier swap.
