What the Atom x5-E3940 is
The Atom x5-E3940 is a quad Apollo Lake edge SoC on BGA 1296 for industrial PCs. It runs 4 Goldmont cores and 4 threads at 1.6 GHz base with bursts to 1.8 GHz. Two megabytes of L2 cache cover edge services. Power is 9.5 W on 14 nm from late 2016 with extended temperature options.
Four cores balance compute with low power for fanless boxes. Bursts cover management tasks while sustained loads hold base. HD Graphics 500 with 12 execution units from 400 MHz to 600 MHz drives 4K signs. The soldered package with ECC options suits unattended operation.
DDR3L with ECC options and LPDDR4 over four channels to 8 GB feed the node. ECC protects remote data. Buyers pick the E3940 where quad edge threads with 4K must fit 9.5 W.
Socket and motherboard compatibility
The E3940 solders to BGA 1296 at 24 × 31 mm with board cooling for 9.5 W. No socket and no later swap exist. Extended temperature boards suit harsh installs. Memory and storage lock at order time.
SoC SATA, USB and NICs surround the cores. The LGA, PGA and BGA: CPU package types explained guide explains soldered embedded design.
Memory, PCIe and cooling
DDR3L-1866 with ECC options and LPDDR4-2133 over four channels to 8 GB suit edge servers. ECC DDR3L fits unattended data. Soldered LPDDR4 fits sealed boxes.
PCIe 2.0 with 6 lanes in x4, x2 and x1 splits serves NICs and NVMe. Two SATA ports add bulk storage. A compact flash array holds logging data.
Cooling uses passive heatsinks for 9.5 W with industrial validation. Bursts trim in hot cabinets. Wide temperature ratings matter more than headline clocks.
Upgrade paths
No soldered upgrade exists. Compare the Intel Atom x5-E3930 at dual core below for gateways, or the Intel Atom x7-E3950 at 1.6 GHz to 2.0 GHz with HD 505 above. All share BGA-1296.
A newer edge SoC needs a new board. The How to find your CPU socket type guide helps identify soldered edge systems.
