I have the 2019 i9 fully maxed out from my employer, and also several M1s (including Pros). When it comes to keeping your hands or feet warm, the i9 is a clear winner. For everything else, it's the M1 ... M3.
Seriously, any M, and especially the Max is a stellar replacement for any Intel MBP, and any workload; especially video, but Blender should perform better as well. The i9 is severly throttled. Otherwise, it'd just melt itself.
Well, I despise Apple, because in addition to being greedy, they're destroying this planet with waste (planned obsolescence, proprietary cable types, soldered everything...) ...and all for short term gains.
That being said, I have nowhere else to go, because Apple is the only company that can give me the product that I need. Intel, and Microsoft Windows are a clown show, and have been since forever (I have a Windows desktop too... had many in the past). I'm a software dev.
If I had a viable option, I'd drop Apple in an instant. Actually, I have dropped the iPhone and iPad already (call it courage), just waiting for a great (quiet, low power and high performing) laptop that will run something similar to OSX, ...and unfortunately, I don't think that Microsoft is ever going to be able to deliver that. I wish Linux could, but not until there's one "consumer" distro, ...and that will also never happen.
I have what he has, and there's no GPU to speak of on the i9 MBP.
If he needs to run Final Cut Pro, he's stuck with Apple, so I don't think that there's a real GPO to speak of.
I believe that the M1,..2 ..3 are the answer, and especially the MAX.
