CPU Comparison

Intel Core i5-7600 vs Intel Core i5-3550

A side-by-side comparison of specs, performance and value. The Intel Core i5-7600 is a high-end mainstream desktop processor launched in early 2017 as part of the 7th Generation Kaby Lake lineup. Positioned just below the unlocked K-series, it features four physical cores without Hyper-Threading, operating at a base frequency of 3.5 GHz with a maximum turbo boost of 4.1 GHz. This represents the highest clock speeds available on a locked 7th Gen i5 processor. Manufactured on Intel's 14nm process, it maintains a 65-watt TDP, making it easy to cool with standard solutions. The processor integrates Intel HD 630 graphics, providing hardware-accelerated 4K media decoding, and supports dual-channel DDR4 memory at 2400 MT/s. While its high clock speeds deliver excellent single-thread performance for gaming and daily applications, the absence of Hyper-Threading limits its multi-threaded throughput. Utilizing the LGA 1151 socket, the i5-7600 was aimed at users seeking top-tier locked performance, though it was quickly overshadowed by the 6-core 8th Gen processors that followed.

Intel Core i5-3550

Our Verdict on Each

Offers the best single-thread performance of the locked 7th Gen i5s, but the 4-core/4-thread limitation makes it a poor choice for modern multi-threaded workloads.

Best for: Upgrading an older LGA 1151 system where maximum single-thread speed is needed without overclocking.

Read the full review

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.
