Intel Core i5-3437U vs Intel Core i5-3230M

A side-by-side comparison of specs, performance and value. The Intel Core i5-3437U is an ultra-low voltage dual-core mobile processor from the third-generation Ivy Bridge lineup, launched in early 2013. Designed specifically for thin-and-light ultrabooks, it operates with a 17-watt thermal design power, enabling deployment in sleek, portable form factors. The processor features two physical cores and four threads, utilizing Hyper-Threading to handle parallel tasks. It runs at a base frequency of 1.9 GHz and can turbo boost up to 2.9 GHz when thermal headroom allows. Built on Intel's 22-nanometer process, it integrates 3 MB of L3 cache and Intel HD Graphics 4000, which features a base frequency of 350 MHz and a max dynamic frequency of 1200 MHz. The 3437U is a slight clock speed bump over the 3337U, offering marginally better performance in bursty workloads. It was engineered to provide a responsive computing experience while maximizing battery life, making it a staple in premium business and consumer ultrabooks of its era.
