Except pink MacBook 12 bit weak weak, in 2016 there was no difference in terms of design than the MacBook 12, 2015. However, in terms of configuration, the difference between the two machines is worth mentioning, especially a some tasks optimized for the new processor chip. In addition, the MacBook 12-2016 speeds longer battery life to about 10 hours, an hour longer than the MacBook 12 2015. The differences between the MacBook and MacBook 12 2015 12 2016 can mention: CPU: If the machine 2015 using Intel Core M first generation (Broadwell), then 2016 was upgraded to Skylake with much better performance and more energy savings. Although the frequency of the two machines are 1.1GHz for the basic version, but clocked maximum TurboBoost chips higher in 2015 than in 2016: 2.4GHz compared to 2.2GHz. However, the actual performance of the machine in 2016 is higher. If the extra money, you will have higher M Core version. Version "max option" clock of 1.3GHz 2016 and 3.1GHz TurboBoost to 1.3GHz and 2.9GHz compared to 2015. The reason of this is leading to Skylake 2016 version better energy management, less heat generation so when necessary, the maximum speed can be pushed further to complete tasks quickly. RAM: 12 2016 on the MacBook, Apple changed the clock from 1600MHz RAM to 1866MHz, improves the memory bandwidth. SSD : in the 2015 version, Apple has used on PCIe SSD (4-lane PCIe 2.0), but in 2016 they were the stronger improve this important memory (2-lane PCIe 3.0). It has a read speed up nearly 30% compared to 2015 but almost double jot. However, you should note that the reading speed of less than 1GB / s is not comparable to the MacBook Pro Retina 15 "in 2015, using the SSD version to 2GB / s, though it was a little faster than the MacBook Pro Retina 15 "2014 GPU: Still using the integrated GPU, but Apple switched to the Core M Skylake HD515 comes instead HD5300 before. According to Intel, the HD515 than the 5300 performance by 40%, but that's not the most important ones. HD515 allows video decoding H.265 / HEVC directly from the hardware, so if you use the task complexity related to video, such as movies and 4K video output, the HD515 will have an advantage over a lot. Battery: According to Apple, the duration of use donated 1 hour, from 9 hours to 10 hours.
