We always find ourselves with the eternal question of whether I have done well in choosing the highest model of the range when we make the purchase of a device because you do not know very well if you can get the most out of it or performance to justify that increase in price with respect to the base model.
That is why Anandtech has made a comparison between these new Macbook Air to see if worth the outlay of 150 Euros more on updating the computer's CPU to Core i7 or we are paying for something that depending on the use that we are going to give it, we will not notice excessively.
Starting with the Core i5 entry model with dual core running at 1,3 Ghz we can see how the difference with last year's model is practically nil, even tilting the balance in favor of the previous model in terms of gross power, leaving Nevertheless lower in other aspects such as battery life mostly due to a higher TDP with 17W compared to the 15W consumed by the new model.
The update of the CPU with an increase of € 150 in the i7 model is quite interesting because here the performance is higher by up to at least 30% in certain benchmarks such as Cinebench R11.5, so we may be compensated for that investment to win in all aspects with respect to the current i5 and the previous Core i7 Ivy Bridge, since apart as we know the SSDs have been updated to be mounted through the PCIe port and thus almost double in speed to previous versions, improvements in Wi -Fi and audio system, in addition to the aforementioned CPU.
