OK. I think the best way to put it is that BIAB requires more computer power than most programs. I would not skimp on the laptop if it were for BIAB and you want a satisfactory experience.

To my knowledge, the most important factor in regenerating RealTracks is the CPU. After that, a fast hard drive to load them. Finally, you should consider having more than the minimum memory. The display is the one thing that doesn't matter.

A good way to measure a computer's fitness for BIAB is the free utility, Geekbench 4. Report the single-core speed.

I realize that the minimum specs given by PG Music are far lower than what I'm describing. Here is what it says: https://www.pgmusic.com/bbwin.requirements.htm

One more thing: if all you want to do is play back MP3 files you make on your desktop and copy to the laptop, then any laptop will do. Playing back audio files is almost no load on a computer at all. I use a little SONY recorder that takes MP3 and WAV files and plug that into a PA. For that matter, playing back frozen BIAB songs also requires less computer power, because they are already converted to audio. It's just (re)generating the songs that takes the power.
