The conversation between human and AI assistant.
Which laptop should I buy out of these three models: Dell Inspiron 3542, HP Pavilion 15-p077TX and Lenovo Z50-70?
And what about processing power?
All three laptops have an Intel Core i5 processor, which should provide a decent amount of processing power. However, the HP Pavilion 15-p077TX has a slightly higher processor speed compared to the other two models.
