CPU Comparison

Core i7-620UE vs Core i7-620UM

A side-by-side comparison of specs, performance and value. The Intel Core i7-620UE is an ultra-low voltage, embedded mobile processor launched in early 2010. Part of the Arrandale family, it is designed specifically for long-lifecycle embedded systems, industrial PCs, and compact fanless devices where reliability and low power consumption are paramount. Operating at a mere 18W TDP, it features 2 cores and 4 threads, running at a conservative base clock of 1.067 GHz with the ability to turbo boost up to 2.133 GHz. The processor utilizes a 32nm CPU die paired with a 45nm graphics and memory controller die, integrating Intel HD Graphics (Ironlake). A standout feature of the 'UE' variant is its support for ECC memory, making it suitable for critical embedded applications requiring data integrity. With 4 MB of Smart Cache and support for AES-NI, the 620UE provided a robust, secure, and efficient computing platform for specialized industrial deployments that required x86 architecture in tight thermal constraints.
