Denis Rusakov tested a MacBook based on an Intel processor and compared its performance with
The host found that professional programsFinal Cut and Logic Pro on Apple MacBook (Intel) perform worse than on a similar device, but on the M1 chip. This became especially noticeable in the last months of work, Denis notes. In June 2020, he purchased a 13-inch MacBook Pro based on a 4-core Intel Core i5, but recently (a month or two ago) it became obvious that a number of applications start and run not as fast as before.
The blogger mainly uses three programs:Final Cut for video editing, Logic Pro for working with audio, Pixelmator Pro for image processing. There have been no problems with the latter so far, but with the first two – vice versa. Denis noticed that video projects have recently begun to take longer to export: if previously a video took 40 minutes to load, now it sometimes even takes longer than an hour. Another problem – When cutting a video, the sound begins to be recalculated (you need to wait a few seconds for this), and this noticeably slows down the work.

As for the sound, problems arose witha project that the presenter has been working on for quite some time. During playback, drum parts start to disappear after a while. This is despite the fact that the rest of the instruments are synchronized.
The expert also emphasized that he useslicensed versions of programs. At the same time, his old iPad is still capable of working with these programs, only it is not as convenient to do it on it as on the MacBook. It turns out that, most likely, the MacBook Pro, which is only 1.5 years old, is being slowed down by Apple for the user to switch to a new model.
