CPU Comparison
Intel Core i5-3550 vs Intel Core i7-3770K
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

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.
Read the full reviewA legendary 2012 CPU that brought 22nm technology to the masses, though its thermal issues and age make it obsolete for modern workloads.
Best for: When considering the Intel Core i7-3770K today, it should strictly be viewed as a legacy component for existing systems. If you already own a functional LGA 1155 motherboard, this processor can provide a cheap and effective upgrade from a Pentium or i3, breathing new life into an older rig for basic office work or retro gaming. However, it is absolutely not recommended for new builds. The lack of Windows 11 official support, high power consumption relative to its performance, and outdated instruction sets make it inefficient. Modern budget processors like the Intel Core i3-12100F will outperform it significantly while drawing a fraction of the power.
