Intel Core M-5Y70

Intel 5Y70

The Intel Core M-5Y70 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 (configurable), the CPU is suited also for passively cooled tablets and 2-in-1 notebooks. In addition to two CPU cores with Hyper-Threading clocked at 1.1 - 2.6 GHz, the chip integrates an HD Graphics 5300 GPU and a dual-channel LPDDR3/DDR3L(-RS) memory controller up to 25.6 GB/s. The Core M is manufactured in a 14 nm process with FinFET transistors.

Architecture

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.

Performance 

The Core M-5Y70 offers a very wide turbo range from 1.1 - 2.6 GHz; however, the actual frequency is largely limited by the TDP. While the CPU is similar to a Core i5-4200U (Haswell, 15 W) in short benchmarks, its performance begins to degrade under continuous full load. Accordingly, the main purpose of Broadwell's higher power efficiency is to reduce power consumption instead of improving raw performance.

Overall, the Core M-5Y70 is sufficient for office and multimedia purposes as well as more demanding applications.

Graphics

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 under continuous 3D load. 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, the Core M-5Y70 draws noticeably less power than the Haswell Y-series (11.5 W). However, the TDP can be set to different values such as 3.5 or 6 W, affacting clock rates and performance. The CPU can be passively cooled even in thin tablets.
