PassMark scores seem to be 5479, 5042, 4882 respectively
So around 11% boost from base model.
I could't find mid tier processor in PassMark webpage. To clarify, the processor are the following:
- Base: Intel® Core™ i5-6267U 2.9 (3.3 TB).
- Mid: Intel® Core™ i5-6287U 3.1 (3.5 TB). (+120€)
- High: Intel® Core™ i7-6567U 3.3 (3.6 TB). (+360€)
All of them include 550 iris pro graphics BUT the main difference is that mid and high level processors have higher clocked graphics frecuency. Comparing the differences and prices between all, in my humble opinion, the mid tier option is the best by far. If you need power the turboboost will give you 3.5ghz (almost the same of i7) and if you need graphics this configuration will give you the same performance of i7! So, the choice is easy!!! The only doubt is to choose 8vs16gb of ram (you have to do a LOT of multitasking to need 16gb) and ssd capacity. It will only depend on your use, so don't follow the advice of anyone. Simply analize your use and make a decision based on that!! Happy to help please share your thoughts!
