CPU Comparison
Core i5-3450S vs Intel Core i5-2500S
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 legacy office workloads well, but sustained multi-core loads cause it to throttle below standard i5-2500 speeds.
Gaming
HD 2500 graphics are too weak for gaming; requires a dedicated GPU for any 3D workloads.
Intel HD 2000 graphics prevent any meaningful modern gaming experience.
Virtualization
Basic VMs are possible but limited by 4 threads.
Good enterprise virtualization feature support, but limited by four total threads.
Efficiency
Highly efficient for its era, tailored for SFF systems.
Excellent efficiency for 2011, drawing significantly less power at idle and light loads than 95 W parts.
Specialized Performance
AI / ML
- No AI acceleration
- Low compute capacity
