Virtualization

Intel Core i5-3330SBest50

Can run a couple of light VMs with VT-d support, but limited by 4 threads.

Intel Core i5-355035

Limited by 4 threads, but VT-x/VT-d support allows basic VM usage.

Efficiency

Intel Core i5-3330SBest70

The 65W TDP and 22nm process provide excellent efficiency for a desktop chip of its era.

Intel Core i5-355060

Good efficiency for 2012, but outdated by modern 14nm/10nm standards.

Our Verdict on Each

A reliable low-power quad-core for its time, good for basic desktop tasks, but severely lacking in graphical and multi-threaded performance today.

Best for: Reviving an old office PC for basic web browsing or as a home NAS server.

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.
