Core i5-3450S Details

The Core i5-3450S stands out for its balanced performance and efficient power design, offering a solid foundation for mainstream desktop computing. Released in 2013 as part of Intel's 3rd generation Core family, this processor is built on a 22 nm process and features a 65 W TDP, making it ideal for systems where thermal efficiency is a priority. Despite its age, the i5-3450S remains a capable performer in its segment, particularly for users who need reliable multitasking without the need for a high-end CPU.

At the heart of the i5-3450S are four cores and four threads, operating at a base frequency of 2.8 GHz and capable of boosting up to 3.5 GHz with Intel's Turbo Boost technology. This allows the processor to deliver responsive performance in single-threaded applications while maintaining efficiency under load. The CPU supports DDR3-1333/1600 memory across two channels, with a maximum capacity of 32 GB and a peak memory bandwidth of 25.6 GB/s, ensuring adequate memory throughput for general productivity and light content creation.

Integrated into the i5-3450S is Intel's HD Graphics 2500 GPU, which features a base frequency of 650 MHz and a burst frequency of up to 1.1 GHz. This GPU supports up to three displays simultaneously and is suitable for basic multimedia playback and light gaming. While not powerful enough for modern AAA titles, it provides a viable option for users who do not require a discrete graphics card.

The i5-3450S supports a range of advanced features, including AVX2, AES-NI, and Intel's vPro technology for enterprise environments. It also includes virtualization extensions (VT-x and VT-d), EIST for dynamic power management, and Intel's TXT for enhanced security. These capabilities make it a versatile choice for both business and home use.

In benchmark testing, the Core i5-3450S achieves an overall score of 4818, placing it at #1012 among 2060 processors. Its single-core performance is rated at 4935, ranking #982, and its multicore score of 4643 places it at #1038. These results indicate that while the i5-3450S is competitive with some modern mid-tier CPUs, it falls behind contemporary processors in both single and multi-threaded performance. It is notably slower than top-tier chips like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which dominate the top 50 lists.

As of March 2026, the Core i5-3450S is best suited for legacy systems, office workstations, or budget builds where integrated graphics and power efficiency are more important than raw performance. While it lacks the modern features and scalability of newer processors, its stability and compatibility with DDR3 memory continue to make it a practical choice for certain use cases.
