I am planning to purchase 4th generation Intel® Core™ i7-4600U 2.10GHz 2.70GHz model. Also, I am thinking of latest version of 8th generation if it has lot of performance difference. Regarding this I have 2 questions.
What is the performance difference between Intel i7 4th generation with 8th generation?
What is the meaning of 2.10GHz 2.70GHz. Is it related to speed or something else?
Guide me whether intel i7 4th generation is it sufficient enough or 8th generation is better?
