Core M 5Y31 Details

The Intel Core M 5Y31 stands out for its impressive single-core performance, ranking #1095 of 2060 in single-core benchmarks with a score of 4764. Despite being a mobile processor from the Broadwell Y architecture, it delivers a strong per-core performance that makes it competitive with more powerful desktop and mobile CPUs in certain workloads. Launched in 2015, the Core M 5Y31 is now over a decade old, placing it among the older processors still referenced in modern performance databases. Its relevance today lies more in its efficiency and integrated graphics capabilities than raw power.

Built on Intel's 14 nm process, the Core M 5Y31 features a dual-core, quad-thread design with a base frequency of 900 MHz and a turbo frequency of up to 2.4 GHz. This allows it to dynamically scale performance based on workload demands while maintaining low power consumption. The processor includes 4 MiB of L3 cache and 512 KiB of L2 cache, supporting efficient data access for everyday computing tasks. With a TDP of just 4.5 W and a down-turbo frequency of 3.5 W at 600 MHz, the Core M 5Y31 is engineered for ultra-low power environments such as thin-and-light laptops and fanless systems.

The integrated Intel HD Graphics 5300 GPU operates at up to 850 MHz and supports up to 16 GB of system memory for graphics processing. It includes support for multiple display outputs and is capable of handling basic multimedia tasks, video playback, and light gaming. While it lacks the graphical power of modern discrete GPUs, its integrated solution is sufficient for users who prioritize battery life and portability over high-end graphics performance.

The Core M 5Y31 supports a wide range of modern instruction sets, including AVX2, AES-NI, and BMI1/BMI2, enabling efficient encryption, compression, and data processing. It also includes Intel's Enhanced SpeedStep and Turbo Boost 2.0 technologies, which allow for dynamic frequency adjustments based on thermal and power constraints. The processor is compatible with Intel's BGA 1515 socket, making it a fit for compact, low-power devices.

In terms of benchmark performance, the Core M 5Y31 achieves an overall score of 4645, ranking #1154 of 2060, and a multicore score of 4467, placing it at #1287. While its multicore performance is modest compared to modern multi-core processors, its single-core strength allows it to hold its own against some higher-end mobile CPUs of its era. Notably, it outperforms several Intel and AMD processors from later generations in single-threaded workloads, showcasing the efficiency of its design.

As of March 2026, the Core M 5Y31 remains a niche option for users seeking ultra-low power consumption and integrated graphics in a small form factor. Its performance is suitable for general productivity, web browsing, and light content creation, but it is not suited for demanding applications like video editing or gaming. For those needing a reliable, energy-efficient processor for lightweight computing, the Core M 5Y31 still offers a compelling balance of performance and power efficiency—despite its age.
