The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Quad-core performance handles basic office tasks well but struggles with modern multitasking demands.
Handles basic office apps, but struggles with heavy multitasking.
Gaming
Same gaming limitations as the i5-3470 — four threads without Hyper-Threading create bottlenecks in modern titles.
Can run older games fine, but lacks single-thread speed for modern AAA titles.
Virtualization
Four cores without Hyper-Threading provide basic virtualization capability.
Limited by 4 threads, but VT-x/VT-d support allows basic VM usage.
Efficiency
The 65W TDP is more efficient than the 77W i5-3470, though modern processors deliver much more performance per watt.
Good efficiency for 2012, but outdated by modern 14nm/10nm standards.

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The i5-3470S offered a good balance of power efficiency and quad-core performance in 2012, but its outdated platform and lack of modern features make it obsolete today.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