CPU Comparison
Intel Core i5-3550S vs Intel Core i5-3570
A side-by-side comparison of specs, performance and value. The Intel Core i5-3550S is a 65W quad-core Ivy Bridge desktop processor with a 3.0 GHz base clock and 3.7 GHz turbo, offering slightly higher clocks than the i5-3470S for power-efficient desktop systems.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The 3.7 GHz turbo provides marginally better performance than the i5-3470S, but the difference is barely noticeable in real-world use.
Handles office apps fine, but struggles with heavy modern web scripts.
Gaming
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.
Great for games from 2012-2015, but bottlenecks modern GPUs heavily.
Virtualization
Same four-core, four-thread design limits virtualization capability as other S-series i5 processors.
Basic VM capability, but limited by 4 threads.
Efficiency
The 65W TDP with slightly higher clocks is well-optimized for the 22nm process, though modern chips deliver far more performance per watt.
Good for 2012, but outdated by modern standards.

Content Creation
Gaming
- 3.7 GHz turbo is the highest among 65W Ivy Bridge i5 models
- Still limited by four threads without Hyper-Threading
- HD 2500 graphics insufficient for gaming
- Modern titles will be CPU-bottlenecked even with a discrete GPU
- Requires a dedicated GPU
- Single-core performance is too low for modern AAA titles
- PCIe 3.0 support helps with GPU compatibility

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The i5-3550S offers slightly better clocks than the i5-3470S within the same 65W envelope, but its outdated platform makes it unsuitable for modern use.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 reviewA 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Best for: The Core i5-3570 is obsolete and should not be considered for a new build.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.
