Intel Core M-5Y70 / M-5Y71 Energy-Efficient and Fast CPU

The Intel Core M-5Y70 / M-5Y71 “Broadwell” dual-core processor is all about energy efficiency and low heat. Still, it manages to provide similar performance to the mid-range Intel Core i3 and i5 U-series “Broadwell” processors such as the i3-4010U and i5-5200U.

That’s a big success since the Intel Core M-5Y70 / M-5Y71 consumes only 4.5 Watts of power, whereas the Core U consumes 15W. As a downside, the Core M features the Intel HD 5300 integrated graphics instead of somewhat faster HD 5500 found on the Core U. Both GPUs, however, aren’t designed for gaming, but they can run some lighter titles.

The excellent thermal characteristics allow the Core M to be used in extremely thin notebooks, with some of them boasting a completely silent fanless design.

The difference between the 5Y70 and 5Y71 are clock speeds. The former runs at between 1.1 and 2.6 GHz, while the latter is clocked at 1.3 – 2.9 GHz. Also the 5Y71 has slightly faster maximal graphics clock of 900MHz versus 850MHz.

Note: The benchmark scores of the listed processors are averages measured across various devices with these processors. The scores and real-world performance of the Intel Core M-5Y70 / 5Y71 and compared CPUs may vary depending on the notebooks' other components, settings, cooling, and other factors. However, the benchmark results are good indicators of the processors' performance.
