CPU Comparison

Intel Core i5-4440S vs Intel Core i5-3570T

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.

Competitors & Alternatives

Intel Core i5-3570T

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 review

An efficient low-power chip for its time, but its low base clock and obsolete platform make it irrelevant for modern use.

Best for: The Core i5-3570T should only be considered if you are upgrading an older LGA 1155 system or building a very low-power home server from salvaged parts. Its 45W TDP and quad-core design make it decent for a DIY NAS or a pfSense router. However, its low base clock of 2.3 GHz makes it sluggish for modern web browsing and everyday multitasking. It is completely unsuited for gaming without a dedicated GPU, and even then, the low clock speeds will bottleneck older titles. Do not spend much money on this processor. If you are building a new system, even the lowest-tier modern Intel N100 or Athlon 3000G will offer vastly superior single-thread performance, efficiency, and modern I/O features.
