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.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Very snappy for daily tasks, but 4 threads limit heavy multitasking.
Handles basic office apps, but struggles with heavy multitasking.
Gaming
Good for older games due to high clocks, but bottlenecks modern GPUs in CPU-heavy titles.
Can run older games fine, but lacks single-thread speed for modern AAA titles.
Virtualization
Limited by core count for running multiple VMs.
Limited by 4 threads, but VT-x/VT-d support allows basic VM usage.
Efficiency
65W TDP offers a good balance of power and heat.
Good efficiency for 2012, but outdated by modern 14nm/10nm standards.

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 reviewA 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.
