What the Core i7-620LE is
The Intel Core i7-620LE is a dual core Arrandale embedded processor from January 2010. It runs two Westmere cores at 2.0 GHz base with Turbo Boost to 2.8 GHz on one core and 2.533 GHz on two cores, with Hyper-Threading for four threads. Each core carries 256 KB of L2 cache with 4 MB of shared L3 cache. Power is rated at 25 W.
The LE suffix marks low voltage embedded with ECC memory and PCIe bifurcation. HD Graphics run at 266 MHz with 566 MHz burst on this SKU. Against the mobile 620LM twin it matches clocks with ECC added for industrial designs.
Memory is DDR3-1066 with ECC in two channels.
Socket and motherboard compatibility
The Core i7-620LE is soldered to the board in BGA 1288 and cannot be replaced.
Firmware must list the sSpec stepping. The CPU cooler compatibility by socket guide covers soldered rules, and the Intel Pentium U5600 page shows another BGA 1288 part.
Memory, PCIe and cooling
Memory is DDR3-1066 with ECC in two channels up to 8 GB.
PCIe 2.0 supports bifurcation on embedded designs.
Cooling is a board specific assembly drawn for 25 W.
Upgrade paths
There is no CPU upgrade path on BGA 1288 because the chip is soldered. A 640LM adds base speed where ECC is not needed.
Frequently asked questions
