Intel Core m5-6Y54

Intel 6Y54

The Intel Core m5-6Y54 is a very power efficient dual-core SoC based on the Skylake architecture and has been launched in September 2015. Thanks to its extremely low TDP, the CPU can be found in passively cooled tablets and 2-in-1 notebooks. In addition to two CPU cores with Hyper-Threading clocked at 1.1 - 2.7 GHz (2 cores: max. 2.4 GHz), the chip also integrates an HD Graphics 515 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The chip is manufactured using a 14 nm process with FinFET transistors.


Skylake replaces both Haswell and Broadwell and brings the same microarchitecture in every TDP class from 4.5 to 45 W. The extensive improvements of the Skylake design include increased out-of-order buffers, optimized prefetching and branch prediction as well as additional performance gains through Hyper-Threading. Overall, however, performance per clock has been increased by only 5 to 10 percent (compared to Haswell) respectively under 5 percent (compard to Broadwell), which is quite modest for a new architecture ("Tock").


Actual performance of the Core m5-6Y54 greatly depends on cooling capabilities and TDP configuration of the related device. While the CPU may be almost similar to a Core i5-6200U (Skylake, 15 W) in short benchmarks, its performance will fall short of a Core i3-6100U under continuous full load. Overall, the chip has sufficient power for office and multimedia purposes as well as somewhat more demanding applications.


The integrated graphics unit called HD Graphics 515 represents the "GT2" version of the Skylake GPU (Intel Gen. 9). The 24 Execution Units, also called EUs, are clocked at 300 - 900 MHz (limited by available TDP headroom) and offer a performance somewhere in range of the old HD Graphics 4400 (Haswell, 15 W). Only a few games of 2015 can be played smoothly in lowest settings.

Power Consumption

Specified at a TDP of 4.5 W (including CPU, GPU and memory controller), the CPU is suited for passively cooled notebooks and tablets. Optionally, the TDP can be lowered to 3.5 watts (cTDP down) or raised to 7 watts (cTDP up), affecting both heat dissipation and performance.
