Core M 5Y71 Details

Ranking #1309 of 2060 in overall performance, the Intel Core M 5Y71 sits well below the top tier of modern processors, reflecting its position as a low-power mobile CPU from an older generation. Released in the early 2010s, this processor is now over a decade old, making it a relic by today's standards. Despite its age, it remains notable for its ultra-low power consumption and integrated graphics, targeting thin and light devices where thermal constraints are critical. As of March 2026, it’s no longer competitive in mainstream computing, but it still holds relevance in niche scenarios such as embedded systems or legacy hardware support.

The Core M 5Y71 is built on Intel’s Broadwell microarchitecture, manufactured using a 14 nm process node, and is designed for mobile devices. It features two cores with four threads, leveraging Intel’s Hyper-Threading technology to improve multitasking efficiency. Base clock speed is set at 1.2 GHz, with a turbo frequency of up to 2.9 GHz, allowing for short bursts of high performance when needed. The processor includes 4 MiB of L3 cache, 512 KiB of L2 cache, and 64 KiB of L1 cache per core, providing a balanced cache hierarchy for its intended use case.

With a TDP of just 4.5 W, the Core M 5Y71 is engineered for power efficiency, making it suitable for fanless designs and extended battery life. It supports up to 16 GB of DDR3L memory at 1333 MHz, with memory bandwidth limited by the DMI 2.0 bus interface. The integrated Intel HD Graphics 5300 GPU runs at up to 900 MHz and supports up to 16 GB of shared memory, enabling basic multimedia playback and light gaming. It also supports up to three display outputs, offering flexibility in multi-monitor setups.

The CPU includes a wide range of instruction set extensions, including AVX, AVX2, AES-NI, and Intel’s Enhanced SpeedStep and Turbo Boost technologies. It supports virtualization with VT-x and VT-d, and includes features like Intel vPro for enterprise management. Despite its age, the processor maintains compatibility with modern operating systems, though performance is constrained by its outdated architecture and limited core count.

In benchmark testing, the Core M 5Y71 scores 4479 overall, 4589 in single-core, and 4313 in multicore performance. While its single-core score places it in the upper tier of older processors, its multicore performance lags significantly behind modern CPUs, particularly in multi-threaded applications. It competes with older Intel and AMD mobile chips such as the Core i5-4300U and Pentium G640, but falls short of even modest current-generation offerings.

In conclusion, the Core M 5Y71 is best suited for light-duty tasks such as web browsing, office applications, and media playback in ultra-portable devices. Its low power draw and compact design make it ideal for legacy systems or embedded use cases, but it lacks the performance and modern features required for demanding workloads. As of March 2026, it serves as a historical example of Intel’s efforts in low-power mobile computing rather than a viable option for new deployments.
