Intel Core i5-450M Details

The Intel Core i5-450M stands as a dual-core mobile processor from Intel's Arrandale generation, released in 2010 as part of the Calpella platform. Built on a 32 nm Westmere microarchitecture, it represents a transitional design that introduced integrated graphics and improved power efficiency for laptops of its era. Though dated by modern standards, the i5-450M was competitive for its time, offering a balance of performance and thermal management suitable for mainstream notebooks. As of March 2026, it is well over a decade old, placing it firmly in the legacy category, yet it remains a relevant reference point when assessing historical performance trends.

At its core, the i5-450M features two physical cores with four threads enabled via Hyper-Threading, running at a base frequency of 2.4 GHz and boosting up to 2.67 GHz. It includes 3 MiB of L3 cache, 0.5 MiB of L2 cache, and 0.125 MiB of L1 cache, with a 2500 MT/s DMI 1.0 bus connecting to the Ibex Peak chipset. The processor operates at a 35 W TDP, making it suitable for thin-and-light laptops. It supports up to 8 GB of DDR3-1066 memory across two channels, with a maximum memory bandwidth of 15.88 GiB/s.

The integrated HD Graphics (Ironlake) GPU operates at 500 MHz base frequency and can burst to 766 MHz, featuring 12 execution units. It supports up to two displays, which was sufficient for basic multimedia and office use. While not capable of modern gaming or content creation, it provided acceptable performance for video playback and light graphics tasks at the time of its release.

The i5-450M supports key technologies such as Intel Turbo Boost 1.0, Enhanced SpeedStep, VT-x, and Extended Page Tables, ensuring a solid foundation for virtualization and power efficiency. It also supports ECC memory, although this is typically limited to server or workstation environments and is rarely found in consumer mobile devices.

In benchmarking terms, the processor scores 4216 overall, with a single-core score of 4105 and a multicore score of 4383. These results place it at #1650 in overall performance, #1677 in single-core, and #1496 in multicore across 2060 CPUs. It sits just behind the Intel Core i5-480M and slightly ahead of the Pentium B940, indicating a competitive position within its generation. The processor's multicore performance is its strongest attribute, slightly outperforming its single-core score, which suggests it benefits more from multi-threaded workloads than from raw clock speed.

Compared to the top-tier CPUs of today, such as the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, the i5-450M is vastly outpaced in both single-core and multicore performance, with a gap measured in thousands of points. However, within its own market segment and era, it delivered a capable and efficient computing experience, especially for users who needed portability without sacrificing too much performance.

In conclusion, the Intel Core i5-450M is a relic of the early 2010s but remains a notable example of Intel's mobile architecture evolution. While obsolete by modern standards, it served as a benchmark for mainstream mobile computing and demonstrated the benefits of integrated graphics and multi-threading in laptops. It is best suited today for educational purposes, legacy system maintenance, or as a reference in performance analysis of older hardware.
