Intel Core m5-6Y57 vs Intel Core i5-4460

Intel Core m5-6Y57

The Intel Core m5-6Y57 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 - 2.8 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.

Architecture

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").

Performance

Actual performance of the Core m5-6Y57 greatly depends on cooling capabilities and TDP configuration of the related device. While the CPU may be 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.

Graphics

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.

Intel Core i5-4460

The Intel Core i5-4460 is a mid range desktop quad-core processor based on the Haswell architecture. It was introduced in Q2 2014 and is manufactured in 22 nm. The processor does not feature Hyperthreading, and therefore can use only 4 threads with the 4 cores.

The performance is on average somewhere between an older Core i5-4430 (similar but lower clocked) and a new Skylake Core i5-6600T. Compared to mobile processors, the performance is similar to a Core i5-6300HQ. Therefore, the performance should be sufficient for all daily tasks and games.

The CPU also integrates a Intel HD Graphics 4600 called graphics card clocked at 350 to 1100 MHz.
