CPU Comparison
Intel Core i5-4440S vs Intel Core i5-3550
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.

Our Verdict on Each
A reliable 65W quad-core CPU ideal for basic legacy systems, but obsolete for modern builds.
Best for: Drop-in upgrade for an existing LGA 1150 system.
Read the full reviewA solid legacy processor that still handles basic tasks, but lacks the performance and modern features needed for current workloads.
Best for: The Core i5-3550 is completely obsolete and should not be considered for a new build. If you are repairing an older LGA 1155 system or building a budget retro gaming rig, it can be a functional, cheap drop-in part. It still handles basic web browsing and document editing adequately, provided you use lightweight software and an SSD. However, its lack of modern instruction sets and low single-thread performance will bottleneck any modern GPU or application. If you have an existing system, it might be worth a cheap upgrade from a Pentium or i3, but otherwise, save your money for a modern platform. Do not spend more than a few dollars on this chip, as even the cheapest new processors offer vastly superior performance-per-watt.
