Celeron 450 Details

Ranking #1869 of 2060 in overall performance, the Intel Celeron 450 sits toward the lower end of the benchmark spectrum, a reflection of its age and entry-level positioning. Launched in August 2008, this processor is now over 17 years old, making it one of the earliest consumer CPUs to feature Intel's Conroe microarchitecture. While it was designed for budget desktop systems, its performance today is dwarfed by modern processors, even those in the same price segment. As of March 2026, the Celeron 450 serves primarily as a nostalgic relic or a component in legacy systems where basic computing tasks are sufficient.

Built on a 65 nm process and featuring a single core with no simultaneous multithreading, the Celeron 450 operates at a base clock of 2.2 GHz, with a clock multiplier of 11 and a core voltage of up to 1.3375 V. It uses the Socket 775 interface and has a 35 W TDP, making it relatively efficient for its time. The processor includes 512 KB of L2 cache and supports DDR1, DDR2, and DDR3 memory via a dual-channel interface, though memory bandwidth is limited by the era's technology. Despite lacking integrated graphics, some compatible chipsets can provide basic display output, allowing for minimal multimedia use.

In benchmark testing, the Celeron 450 scores 4021 overall, with a single-core score of 3870 and a multicore score of 4247. Its single-core performance places it just behind the Core 2 Duo E4400 and slightly ahead of the Athlon II P360, while its multicore score is only marginally higher than several Atom and low-power AMD processors. These results indicate that while the Celeron 450 was capable of handling basic office applications and web browsing in its era, it struggles with modern multitasking and computational workloads.

The processor supports a range of Intel instruction sets, including MMX, SSE, SSE2, SSE3, and SSSE3, but lacks support for SSE4, which limits its compatibility with some contemporary software and games. It also features a locked clock multiplier, which restricts overclocking potential. With a transistor count of 105 million and a die area of 77 mm², the Celeron 450 represents a compact and cost-effective design typical of Intel's early 2000s desktop offerings.

In conclusion, the Intel Celeron 450 is best suited for legacy systems, retro computing enthusiasts, or as a replacement CPU in older machines where minimal processing power is required. While its 2.2 GHz clock speed may seem respectable by today’s standards, its age and single-core architecture make it obsolete for modern use. For users seeking more than basic functionality, even entry-level current-generation processors offer vastly superior performance and efficiency.
