Before launch of the new 12 ″ MacBook last Friday, we saw some benchmarks of the base model of this team that rides a 1,1 GHz Intel Core M processor, giving a result in CPU performance more or less on par with the 2011 model of the MacBook Air if we stick to the numbers thrown by the famous Geekbench application.
Now with the equipment available for purchase, some lucky ones have been able to get hold of the mid-range that mounts the same Intel Core M processor but this time at 1,2 GHz, so we already have in our hands some tests carried out on them , which reveal a significant increase in the performance over low-end chip especially on such important benchmarks as multi-core performance, not so much for single-core benchmarks.
Although the results are still not conclusive (we will have to wait to see more tests), the result in performance of operations that require a single core is close to 2600 points in the 64-bit benchmark and more than 5300 in the tests that require several cores. . That performance with just 100 MHz higher clock speed is significantly better, especially on multicore, when compared to approximately 2400 points and 4450 points respectively for the 1.1 GHz model, which means that the mid-range model appears to be showing performance improvements with a 9 percent increase in CPU frequency.
This mid-range 12 ″ MacBook ranks on the same level in performance as the entry-level 2014 MacBook Air, which doesn't seem bad at all compared to what we saw in the low-end with the 1,1 GHz core M.
Actually the chip is the same, that is, the low-end uses a 5Y51 chip running at 1,1Ghz and that Apple has taken as the basis for the mid-range, raising the clock speed 100 MHzHowever, the high-end uses a chip with 5Y71 nomenclature that works based on 1,2GHz and that Apple as an option will increase 100MHz to 1,3GHz without the power consumption being increased, reaching between 4,5 and 6 watts per hour.
