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.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Can handle basic document editing, but struggles with heavy multitasking or modern web apps.
Handles office apps fine, but struggles with heavy modern web scripts.
Gaming
Severely bottlenecks modern GPUs. Only viable for pre-2015 games at low settings.
Great for games from 2012-2015, but bottlenecks modern GPUs heavily.
Virtualization
Limited to very light virtualization due to lack of Hyper-Threading.
Basic VM capability, but limited by 4 threads.
Efficiency
Efficient for its era, but completely outclassed by modern 10nm and 7nm processors.
Good for 2012, but outdated by modern standards.

Our Verdict on Each
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 reviewA 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Best for: The Core i5-3570 is obsolete and should not be considered for a new build.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.
