Core M 5Y70 Details

The Intel Core M 5Y70, released in 2015, is a low-power mobile processor built on the Broadwell Y microarchitecture at a 14 nm process node. Designed for ultra-portable devices, it features a dual-core, quad-thread configuration with a base clock of 1.1 GHz and a single-core turbo frequency of up to 2.6 GHz. Despite being nearly a decade old, the processor remains relevant in niche applications due to its exceptionally low 4.5 W TDP and integrated Intel HD Graphics 5300, which supports up to 16 GB of shared memory. The chip includes 4 MiB of L3 cache and 512 KiB of L2 cache per core, with 64-bit support and a 5000 MT/s DMI 2.0 bus interface. It supports a range of modern instruction sets, including AVX, AVX2, AES-NI, and Intel's Turbo Boost 2.0, though it lacks support for more recent extensions like AVX-512.

In benchmark testing, the Core M 5Y70 achieves an overall score of 4405, ranking #1391 out of 2060 processors, with a single-core score of 4370 (#1419) and a multicore score of 4457 (#1308). These results place it behind contemporary mainstream desktop and mobile processors but within reach of some older-generation chips like the Core i5-2540M and the Pentium Silver N6000. Its performance is constrained by its outdated architecture and limited thermal headroom, which restricts sustained clock speeds. While the single-core score is modest compared to modern high-performance CPUs, the processor delivers reasonable efficiency for light productivity tasks.

The Core M 5Y70 is best suited for thin and light laptops, fanless systems, or embedded applications where power efficiency and compact size are prioritized over raw performance. Its integrated graphics support up to four displays and can handle basic multimedia playback, but it is not capable of running modern games or intensive creative software. As of March 2026, the processor is considered obsolete for general computing, but it may still serve well in legacy systems or low-demand environments where energy consumption and heat generation are critical factors. While it no longer competes with today’s high-end processors, its design reflects Intel’s early push into the ultra-low-power mobile market.
