Core i3-5157U Details

As of March 2026, the Intel Core i3-5157U remains a relic from the mid-2010s, representing a mobile processor launched in March 2015 as part of Intel's Broadwell-U lineup. While it was once a mainstream offering for thin and light laptops, its relevance has faded significantly in the current computing landscape. Despite its age, the processor still holds a modest place in historical performance rankings, offering a glimpse into the evolution of mobile computing efficiency and integrated graphics capabilities. The Core i3-5157U is built on a 14 nm process and features a dual-core design with Hyper-Threading, enabling it to handle four threads simultaneously.

With a base frequency of 2.5 GHz and a TDP of just 28 W, it was designed for power efficiency, making it suitable for lightweight workloads in compact devices. The processor supports DDR3 memory up to 1866 MT/s through a dual-channel interface, delivering a memory bandwidth of 29.9 GB/s. It also includes 3 MB of L3 cache, enhancing data access speed for common applications. The integrated Intel Iris 6100 GPU, with a max frequency of 800 MHz, provides basic graphics performance suitable for everyday use, including HD video playback and light multimedia tasks.

However, it lacks support for modern GPU technologies like DirectX 12 or advanced compute features, limiting its usefulness in gaming or creative work. In terms of real-world performance, the Core i3-5157U scores 4541 overall in benchmark tests, ranking #1243 out of 2060 processors. Its single-core performance of 4618 places it at #1202, indicating decent efficiency for older applications and single-threaded workloads. The multicore score of 4426, ranked #1394, reflects its modest scaling in multi-threaded environments.

These results position the i3-5157U between older dual-core CPUs like the Core i5-3437U and slightly newer models like the Core i7-860S, but far behind modern processors in both performance and efficiency. While the CPU supports advanced instruction sets such as AVX2 and AES-NI, and includes virtualization features like VT-x and VT-d, its locked multiplier restricts overclocking potential. Given its age and limited capabilities, the Core i3-5157U is best suited for legacy systems, basic office tasks, or as a secondary device where power consumption and heat are critical concerns. It stands as a testament to Intel's focus on mobile efficiency during the Broadwell era, but offers little value in today's high-performance computing environment.
