Core i5-3337U Details

The Intel Core i5-3337U stands as a mid-tier mobile processor from the Ivy Bridge generation, released in 2013. As of early 2026, it is a four-year-old design, placing it firmly in the realm of legacy hardware. While outdated by modern standards, it remains a relevant reference point for understanding the evolution of low-power, dual-core performance. Its benchmark scores reflect its age, with an overall score of 4378, ranking it #1432 out of 2060 processors in the dataset. In single-core performance, it scores 4474, placing it at #1312, slightly ahead of several modern low-power processors like the Core M-5Y71 and Core m5-6Y54, which highlights its historical competitiveness in single-threaded workloads.

This processor is built on a 22 nm process and uses the FCBGA1023 socket, designed for ultra-thin laptops. It features two cores with four threads enabled via Intel's Hyper-Threading technology, allowing it to handle multithreaded tasks more efficiently than a traditional dual-core. Clock speeds range from a base of 1.8 GHz to a turbo frequency of 2.7 GHz, supported by a 5 GT/s bus speed. Despite its modest 17 W TDP, the i5-3337U delivers reasonable performance for basic productivity and light multimedia use, though it is outpaced by nearly every modern processor in the top 50.

The i5-3337U integrates Intel HD Graphics 4000, which supports up to three displays and operates at a base frequency of 350 MHz with a burst frequency of 1.1 GHz. This GPU, while adequate for office applications and HD video playback, lacks the power for modern gaming or GPU-intensive tasks. The processor supports DDR3-1333 and DDR3-1600 memory, with a maximum of 32 GB and a bandwidth of 25.6 GB/s across two memory channels. It also supports key technologies such as AES-NI, AVX2, and Intel vPro, making it suitable for enterprise environments that require secure boot and remote management.

In terms of benchmark performance, the i5-3337U ranks #1949 in multicore performance with a score of 4235, just behind several older dual-core CPUs like the Core 2 Duo T6400 and T6500. Its multicore score is significantly lower than modern processors such as the Ryzen 9 9950X3D (#1 overall) or even the Core i9-14900K (#9), emphasizing the performance gap between 2013-era silicon and today's high-end chips. While it holds its own in single-core performance relative to some modern low-power chips, its overall multicore weakness makes it unsuitable for demanding applications like video editing or 3D rendering.

In conclusion, the Core i5-3337U is best suited for users requiring a reliable, low-power processor for basic computing tasks such as web browsing, document editing, and media playback. As of March 2026, it remains a capable but outdated option, with its strengths limited to power efficiency and legacy compatibility. For modern workloads, it is far outclassed by newer processors, particularly those in the top 50, which offer vastly superior performance and feature sets.
