CPU Comparison

Core i5-3450 vs Intel Core i5-3570

A side-by-side comparison of specs, performance and value. The Intel Core i5-3450 is a mainstream desktop processor launched in April 2012 as part of the Ivy Bridge architecture. Designed for the LGA 1155 socket, it brought the 22nm manufacturing process to the masses, offering a significant efficiency improvement over Sandy Bridge. This quad-core processor operates at a base frequency of 3.1 GHz and boosts up to 3.5 GHz. It features 6MB of L3 cache and supports dual-channel DDR3-1600 memory. The inclusion of Intel HD 2500 integrated graphics provided basic display capabilities, though it was not intended for gaming. With a 77W TDP, it balanced power consumption and performance adequately for its time. While it lacks Hyper-Threading and an unlocked multiplier, it became a favorite for budget builders and system integrators, providing reliable performance for everyday computing and gaming when paired with a dedicated GPU.

Our Verdict on Each

Core i5-3450Situational

A solid workhorse for 2012, but its 4-core/4-thread design and HD 2500 graphics make it obsolete for modern workloads.

Best for: Purchasing a $10 used office PC for basic web browsing

Read the full review

A legendary processor for its time that still handles basic tasks, but is completely outclassed by modern budget CPUs.

Best for: The Core i5-3570 is obsolete and should not be considered for a new build. However, if you are repairing or upgrading an older LGA 1155 system, it is an excellent, cheap drop-in part. It still handles basic web browsing and document editing adequately, provided you use lightweight software and an SSD. For retro gaming, when paired with a dedicated GPU from the same era (like a GTX 660 or 750 Ti), it can run games from the early 2010s flawlessly. It is also a solid choice for a basic home server. Do not spend much money on this chip, as modern budget processors offer vastly superior performance-per-watt. If you already have the motherboard, it's a great salvage build; otherwise, look elsewhere.
