CPU Comparison
Intel Core i5-3470 vs Intel Core i5-3550S
A side-by-side comparison of specs, performance and value. The Intel Core i5-3470 is a quad-core desktop processor from the Ivy Bridge family, offering solid mainstream performance with a 3.2 GHz base clock, 3.6 GHz turbo, and 77W TDP for budget-conscious builders.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Quad-core performance handles basic office tasks but struggles with modern multitasking and heavy productivity workloads.
The 3.7 GHz turbo provides marginally better performance than the i5-3470S, but the difference is barely noticeable in real-world use.
Gaming
When paired with a modern GPU, the i5-3470 can handle very light or older games, but the lack of threads creates significant bottlenecks in modern titles.
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.
Virtualization
Four cores without Hyper-Threading provide basic virtualization capability but are limited by today's standards.
Same four-core, four-thread design limits virtualization capability as other S-series i5 processors.
Efficiency
The 77W TDP was reasonable for 2012 but is inefficient compared to modern quad-core processors that consume half the power.
The 65W TDP with slightly higher clocks is well-optimized for the 22nm process, though modern chips deliver far more performance per watt.

Our Verdict on Each
The i5-3470 was a reliable mainstream quad-core in 2012, but its lack of Hyper-Threading, outdated platform, and DDR3 memory make it obsolete for modern builds.
Best for: Maintaining an existing legacy system for basic office or web tasks
Read the full reviewThe i5-3550S offers slightly better clocks than the i5-3470S within the same 65W envelope, but its outdated platform makes it unsuitable for modern use.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
