Core i3-2377M Details

For users seeking a lightweight, energy-efficient mobile processor with integrated graphics, the Intel Core i3-2377M offers a modest but functional solution. Released in September 2012, this CPU is now over a decade old, placing it firmly in the category of legacy hardware. Designed for the mobile market, it is built on Intel’s Sandy Bridge microarchitecture and fabricated using a 32 nm process. With a TDP of just 17 W, it emphasizes power efficiency, making it suitable for thin and light laptops where thermal constraints are a priority.

The Core i3-2377M features two physical cores with Simultaneous Multithreading (SMT), effectively delivering four threads. It operates at a base frequency of 1.5 GHz and supports Intel's Enhanced SpeedStep technology for dynamic clock adjustments. The processor includes 3 MB of L3 cache and 0.5 MB of L2 cache, with 0.0625 MB of L1 cache per core, distributed across instruction and data caches. It supports dual-channel DDR3 memory at speeds up to 1333 MHz, enabling a maximum memory bandwidth of approximately 19.87 GiB/s. The integrated Intel HD 3000 graphics unit provides basic visual performance, featuring 12 execution units and a base frequency of 350 MHz, with a maximum boost of 1.0 GHz, supporting up to two displays.

Despite its age, the Core i3-2377M supports a wide range of modern features, including Intel Virtualization Technology (VT-x), Extended Page Tables (EPT), and Intel Identity Protection Technology. It also supports Advanced Vector Extensions (AVX), enabling improved performance in compute-intensive applications. The processor is equipped with Intel’s Hyper-Threading technology, which enhances multitasking efficiency by allowing each core to handle two threads simultaneously.

In benchmark testing, the Core i3-2377M achieves an Overall Score of 4129, ranking #1772 out of 2060 processors. Its Singlecore Score stands at 3807, placing it #1884, while its Multicore Score is 4612, ranking #1071. These results indicate that the processor is significantly outperformed by modern CPUs, even in its tier. The top 50 list in multicore performance includes processors with scores over 12,000, highlighting the vast gap between contemporary and legacy hardware. However, within its original market segment, the Core i3-2377M was competitive for basic productivity and media consumption tasks.

As of March 2026, the Core i3-2377M is best suited for legacy systems, entry-level laptops, or as a component in low-power embedded applications where energy efficiency and compatibility with older systems are more important than raw performance. It remains a testament to Intel’s early integration of advanced features like AVX and SMT in mobile platforms, but its age and limited performance make it impractical for modern workloads such as gaming, content creation, or software development.
