CPU Comparison
Core i7-4850EQ vs Core i7-940XM
A side-by-side comparison of specs, performance and value. The Intel Core i7-4850EQ is a mobile processor launched in 2013, designed for embedded systems and high-performance mobile workstations. Built on the 22-nanometer Haswell architecture, it was part of the Crystalwell family, notable for integrating a massive 128 MB L4 eDRAM cache. The processor features four cores and eight threads, operating at a base frequency of 1.6 GHz and boosting up to 3.2 GHz. This low base clock and high turbo capability allowed it to scale efficiently based on thermal loads. It includes 8 MB of L3 cache and integrates Intel HD Graphics 5200, also known as Iris Pro, which utilizes the eDRAM for massive bandwidth gains. With a 47-watt thermal design power, it was engineered for devices requiring desktop-class graphics and compute power in constrained mobile or embedded form factors. Though end-of-life, it remains a historically significant chip for its innovative packaging indeed.
