CPU Comparison

Intel Core i5-4440S vs Intel Core i5-3330S

A side-by-side comparison of specs, performance and value. The Intel Core i5-4440S is a 4-core, 4-thread desktop processor launched in September 2013 as part of the Haswell generation. Operating on a 22nm manufacturing process, this CPU was designed for budget-conscious builders who needed reliable performance without the high power draw. With a base clock of 2.8 GHz and a turbo boost of up to 3.3 GHz, it delivered solid everyday computing and moderate multitasking capabilities. The 'S' suffix denotes a lower power profile, locking the TDP at 65 watts compared to the standard 84-watt models. This made it an ideal choice for small form factor builds and office environments where thermal management was crucial. It includes Intel HD 4600 integrated graphics, allowing for media playback and light gaming without a dedicated GPU. Although long surpassed by modern standards, it remains a notable example of Intel's efficiency-focused engineering during the early 2010s.
