Performance Compared

Productivity

Intel Core i5-3470S24

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

Intel Core i5-3550SBest25

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

Gaming

Intel Core i5-3470S17

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

Intel Core i5-3550SBest18

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

Intel Core i5-3470S14

Four cores without Hyper-Threading provide basic virtualization capability.

Intel Core i5-3550SBest15

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

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 i5-3550S40

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