CPU Comparison
Core i5-3450S vs Intel Core i5-3570S
A side-by-side comparison of specs, performance and value. The Intel Core i5-3450S is a low-power desktop processor released in April 2012 as part of the Ivy Bridge lineup. Designed for small form factor PCs and AIOs, it features a 65W TDP, down from the standard 77W. It operates at a base frequency of 2.8 GHz and can boost up to 3.5 GHz, providing a good balance between power consumption and burst performance. The processor includes 4 cores and 4 threads, alongside 6MB of L3 cache. It supports dual-channel DDR3 memory and features Intel HD 2500 integrated graphics. While the HD 2500 is basic, it suffices for media playback and standard display tasks. The 'S' suffix ensures it runs cooler than standard chips, making it ideal for compact systems where fan noise and thermals are a concern. It was a popular OEM choice for office machines and HTPCs.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office tasks well, but low base clock limits heavy multitasking.
Handles office suites and multitasking well enough for basic use.
Gaming
HD 2500 graphics are too weak for gaming; requires a dedicated GPU for any 3D workloads.
Quad cores are okay for old games, but single-thread speed is too low today.
Virtualization
Basic VMs are possible but limited by 4 threads.
Can run a basic VM, but lacks Hyper-Threading.
Efficiency
Highly efficient for its era, tailored for SFF systems.
Good efficiency for a 22nm desktop chip.

Our Verdict on Each
A reliable low-power CPU for 2012 SFF builds, but outdated and slow for modern workloads.
Best for: Restoring an old SFF office PC
Read the full reviewA well-balanced 65W quad-core that was a staple in pre-built office PCs, but is too slow for modern demanding workloads.
Best for: For modern users, the Core i5-3570S holds very little value outside of maintaining an older system. If you have a functioning LGA 1155 motherboard and need a cheap processor to keep an office machine or media center running, this chip is adequate. Its quad-core design still handles basic web browsing and document editing reasonably well. However, it struggles significantly with modern gaming and heavy multitasking. It should never be purchased for a new build, as its platform lacks support for modern I/O like NVMe booting (on most older boards), USB 3.1 Gen 2, and DDR4 memory. If you find one used for a few dollars, it might be worth it to revive an old PC. Otherwise, save your money for a modern entry-level processor.
