Performance Compared

Productivity

Intel Core i5-3550S25

The 3.7 GHz turbo provides marginally better performance than the i5-3470S, but the difference is barely noticeable in real-world use.

Intel Core i5-3570Best55

Handles office apps fine, but struggles with heavy modern web scripts.

Gaming

Intel Core i5-3550S18

The slightly higher clocks provide a marginal improvement over the i5-3470S but the same fundamental limitations apply — four threads without HT bottleneck modern gaming.

Intel Core i5-3570Best40

Great for games from 2012-2015, but bottlenecks modern GPUs heavily.

Virtualization

Intel Core i5-3550S15

Same four-core, four-thread design limits virtualization capability as other S-series i5 processors.

Intel Core i5-3570Best40

Basic VM capability, but limited by 4 threads.

Efficiency

Intel Core i5-3550S40

The 65W TDP with slightly higher clocks is well-optimized for the 22nm process, though modern chips deliver far more performance per watt.

Intel Core i5-3570Best65

Good for 2012, but outdated by modern standards.

Intel Core i5-3570

Our Verdict on Each

The i5-3550S offers slightly better clocks than the i5-3470S within the same 65W envelope, but its outdated platform makes it unsuitable for modern use.

Best for: Maintaining an existing SFF desktop that already uses this processor

Read the full review

A legendary processor for its time that still handles basic tasks, but is completely outclassed by modern budget CPUs.

Best for: The Core i5-3570 is obsolete and should not be considered for a new build. However, if you are repairing or upgrading an older LGA 1155 system, it is an excellent, cheap drop-in part. It still handles basic web browsing and document editing adequately, provided you use lightweight software and an SSD. For retro gaming, when paired with a dedicated GPU from the same era (like a GTX 660 or 750 Ti), it can run games from the early 2010s flawlessly. It is also a solid choice for a basic home server. Do not spend much money on this chip, as modern budget processors offer vastly superior performance-per-watt. If you already have the motherboard, it's a great salvage build; otherwise, look elsewhere.
