I think Dan needs to learn what Blender is used for as his explaining is not that great.
Saving 5 mins on a single image is HUGE saving. If you render animation and each second has 24 frames (film) you are saving 2!!! hours per second of footage.
Its unlikely that you do this on a production thing, but for students or small freelancers, that is a BIG deal.
Talking about 5 mins a day (as Dan put it) is really not the right comparison as its never just a single frame.
Perhaps, but... why would you render anything like that with a laptop (multiple days for a 30 second clip)? A $500 GPU would outperform an M3 Max ($4000+) any day. Are you really going to set your brand new laptop in a corner and let the fans churn for days on end? Are you going to do this regularly? A student/freelancer could buy a reasonably priced laptop AND a desktop for that price, and come out way ahead. An MBP is nice, but it's not the right tool for that job.
Exporting a video is a much more reasonable scenario, and the difference in that is much less significant in that use case. It's not like you can't do anything else while a video is exporting unless you're lazy like me, in which case the slower the better!
