What the Xeon E-2278GE is
The Xeon E-2278GE brings eight cores with Hyper-Threading to embedded designs at 80 W. It launched in June 2019 with a 3.3 GHz base and up to 4.7 GHz boost. Intel lists it as Embedded with broad market support for imaging and automation fleets.
Sixteen megabytes of Smart Cache feed machine vision and data logging across sixteen threads. The moderate base clock balances throughput with enclosure thermals. Boost reaches 4.7 GHz for single thread control loops.
UHD Graphics 630 from 350 MHz to 1.2 GHz drives operator panels without discrete cards. The process is 14 nm and the multiplier is locked. ECC memory protects continuous runs. The $519 manufacturer price covers tray supply for integrators.
Socket and motherboard compatibility
The E-2278GE fits LGA 1151 on revision 2 embedded boards only. C246 boards with extended life BIOS builds pair ECC UDIMMs with locked display outputs for factory use. Validate the exact board revision for multi year deployment.
Consumer 300 series boards may post where listed, but long supply and thermal ratings live on embedded variants. Revision 1 boards never accept it. The Socket vs chipset: what decides whether a CPU works guide explains chipset matching.
Single socket nodes are the deployment unit. There is no dual socket path, so larger fleets add nodes rather than sockets.
Memory, PCIe and cooling
DDR4-2666 ECC UDIMMs in two channels up to 128 GB suit vision controllers and edge servers. Dual channel bandwidth near 41.6 GB per sec feeds frame buffers. Choose rugged DIMMs where vibration matters.
Sixteen Gen3 CPU lanes can hold capture cards or fast networking while integrated graphics handle local UI. Chipset lanes add serial and USB for machine I/O. Lane splits follow the embedded board manual.
Cooling needs a rated 80 W solution for the deployment ambient, not just a desktop tower rating. The 75 mm LGA 1151 pattern from the CPU cooler compatibility by socket guide still applies for mounting, but heatsink choice follows the enclosure vendor.
Upgrade paths
On the same socket, the Intel Xeon E-2278GEL trims to 35 W at lower clocks for fanless or sealed boxes. The Intel Xeon E-2226GE drops to six cores at the same 80 W for lower cost vision nodes. Both share embedded C246 after requalification.
Workstation E-2278G gives similar cores with P630 graphics for office towers rather than embedded fleets. It lacks long supply terms.
Past LGA 1151 embedded generations move to newer sockets. The E-2278GE covers eight core embedded vision where ECC must run for years.
Frequently asked questions
What socket does the Intel Xeon E-2278GE use?
It uses LGA 1151 on revision 2 embedded boards with C242 or C246.
How many cores does the E-2278GE have?
