I am not a techy, just so you know my level  of information. It's A Very Fast processor, downloads are quick, screen is nice size & excellent quality for movies, it is easy to use, I experienced no problems with transition from my old to my new Lenovo computer, it is space convenient. I love that a processor is not in a separate piece of equipment  as I wanted to relocate my computer to the main floor of my home and didn't want a lot of clutter around.  Convenient for the elderly.  The only thing I would change is that I wish I could move the screen up and down vertically.  I am so happy with this computer!
