So, how much faster is a 2018 MBP with 2.8GHz Core i9 (32GB RAM) than a 2014 MBP with 2.8 GHz Intel Core i7 (16GB RAM) in editing 4K video files? How about other things like... editing photos in photoshop/lightroom etc..? Would the 2018 model be a LOT faster than the 2014 model? Would there be a considerable difference? Thank you very much in advance!
