CPU Comparison
Intel Core i5-3550 vs Intel Core i5-7600K
A side-by-side comparison of specs, performance and value. The Intel Core i5-3550 is a 4-core desktop processor introduced in April 2012 as part of the Ivy Bridge family. Built on a 22 nm process, it features a base clock of 3.3 GHz and a turbo boost of up to 3.7 GHz. Designed for standard desktop computing, it includes 6 MB of L3 cache and supports dual-channel DDR3 memory. Unlike its 'K' series counterparts, the multiplier is locked, limiting overclocking capabilities. It integrates Intel HD 2500 graphics, which are suitable for basic display output but not for gaming. With a TDP of 77 W, it balances power consumption and performance, making it a reliable choice for budget builds and office systems. While it has reached end-of-life status, it remains functional for basic computing tasks and legacy systems requiring LGA 1155 socket compatibility.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office apps, but struggles with heavy multitasking.
Snappy for daily tasks but fails in multi-threaded rendering.
Gaming
Can run older games fine, but lacks single-thread speed for modern AAA titles.
High clocks help older games, but 4 threads cause severe stuttering in modern titles.
Virtualization
Limited by 4 threads, but VT-x/VT-d support allows basic VM usage.
Poor for VMs due to lack of threads.
Efficiency
Good efficiency for 2012, but outdated by modern 14nm/10nm standards.
91W TDP increases significantly when overclocked.

Our Verdict on Each
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.
