Performance Compared

Productivity

Intel Core i5-3470S24

Quad-core performance handles basic office tasks well but struggles with modern multitasking demands.

Intel Core i5-3550Best50

Handles basic office apps, but struggles with heavy multitasking.

Gaming

Intel Core i5-3470S17

Same gaming limitations as the i5-3470 — four threads without Hyper-Threading create bottlenecks in modern titles.

Intel Core i5-3550Best30

Can run older games fine, but lacks single-thread speed for modern AAA titles.

Virtualization

Intel Core i5-3470S14

Four cores without Hyper-Threading provide basic virtualization capability.

Intel Core i5-3550Best35

Limited by 4 threads, but VT-x/VT-d support allows basic VM usage.

Efficiency

Intel Core i5-3470S40

The 65W TDP is more efficient than the 77W i5-3470, though modern processors deliver much more performance per watt.

Intel Core i5-3550Best60

Good efficiency for 2012, but outdated by modern 14nm/10nm standards.

Competitors & Alternatives

Intel Core i5-3550

Our Verdict on Each

The i5-3470S offered a good balance of power efficiency and quad-core performance in 2012, but its outdated platform and lack of modern features make it obsolete today.

Best for: Maintaining an existing SFF desktop for basic computing tasks

Read the full review

A 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.
