Intel Core M-5Y10

Intel 5Y10

The Intel Core M-5Y10 is an ULV (ultra-low voltage) dual-core SoC based on the Broadwell architecture launched in September 2014. Thanks to its TDP of just 4.5 W, the CPU is suited for passively cooled tablets and 2-in-1 notebooks. In addition to two CPU cores with Hyper-Threading clocked at 0.8 - 2.0 GHz, the chip also integrates an HD Graphics 5300 GPU and a dual-channel LPDDR3/DDR3L(-RS) memory controller up to 25.6 GB/s. The chip is manufactured in a 14 nm process with FinFET transistors.

While the Core M-5Y10 supports "Config Down TDP" for an optional TDP of only 4 W, the very similar 5Y10a doesn't.


Broadwell represents the "Tick" in Intel's Tick-Tock model, which means a shrink of its predecessor Haswell. The new 14 nm manufacturing process with three-dimensional FinFET transistors allows not only improvements in energy efficiency, but also a significantly smaller die size fit for more compact packages and devices.

Further advantages result from the revised microarchitecture of Broadwell. Due to its improved branch prediction, bigger buffer sizes (1500 instead of 1000 entries in the L2 TLB) and other tweaks, the performance per clock has been increased by more than 5 percent over its predecessor. There are also some new instruction set extensions designed for cryptographic applications.


The Core M-5Y10 offers a very wide turbo range from 0.8- 2.0 GHz; however, the actual frequency is largely limited by the TDP. Under continuous full load, the core clock will begin to degrade. Overall, the performance is similar to a Core i3-4030U (Haswell, 15 W) and sufficient for office and multimedia purposes as well as more demanding applications.


The integrated HD Graphics 5300 offers 24 Execution Units (EUs) clocked at 100 - 850 MHz. Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock. However, the GPU frequency is also limited by the TDP, which prevents significant performance boosts over the older HD 4200. Only a few games as of 2014 are playable in low settings and XGA resolution.

Broadwell is the first Intel chip to fully support DirectX 11.2 as well as OpenCL 1.3/2.0 and OpenGL 4.3. Video will output natively via DisplayPort 1.2 or HDMI 1.4a. However, the new HDMI 2.0 standard is not officially supported.

Power Consumption

With a TDP of only 4.5 W (4.0 W with Config Down TDP), the Core M-5Y10 draws noticeably less power than the Haswell Y-series (11.5 W). The CPU can be passively cooled even in thin tablets.
