CPU Comparison
Core i7-620LE vs Core i7-620LM
A side-by-side comparison of specs, performance and value. The Intel Core i7-620LE is a low-power, embedded mobile processor launched in early 2010 based on the Arrandale architecture. Designed for long-lifecycle industrial PCs and fanless embedded systems, it operates on a 25W thermal envelope. The processor features 2 cores and 4 threads, running at a base clock of 2.0 GHz with a max turbo boost of 2.8 GHz. A key differentiator of the 'LE' variant is its support for ECC memory, ensuring data integrity for critical applications. It utilizes a 32nm CPU die paired with a 45nm graphics and memory controller die, integrating Intel HD Graphics (Ironlake). With 4 MB of Smart Cache and AES-NI support, the 620LE provided a secure and reliable computing platform for specialized industrial deployments requiring x86 compatibility within tight thermal constraints, distinguishing itself from consumer mobile chips.
