My history from private and work Macs I used
- had 15" MBPs from 2010, 2013
- a 13" Intel 2019
- a 16" Intel 2020 64GB everything max
- a 14" M1 Pro 32GB
- then again the 13" Intel 2019 for a while
- now 15" M2 24GB 1TB
So I had a fair few to compare. I
prefer the 15" M2 but I can see why some would pick the 14/16 Pros. I don't really judge the costs/perf as I don't really care, I can afford whatever I need, i use it soo much everyday,
I just need the maximum utility whichever may provide it.
- screen the 15" has the best screen you can get on notebooks outside of MiniLED and OLED ones. Windows notebooks have better 4k OLED screens but the resolution is all you ever need and MiniLED, OLED only wins in media consumption but in normal SDR content during daylight I would not say it makes any difference at all.
- if you do media work -> MiniLED is better
- if you play games or watch movies at night -> MiniLED is better
- if you need a workhorse for development/studying/office work the 15" still has the same colors and brightness (I do have my wifes 14" M1 Pro right next to mine)
- 120hz vs 60hz I don't really notice at all. Switching from the 13" Intel 2019 (Iris Pro) the 60hz M2 seems to super smooth. Big difference coming from an Intel GPU, but nothing I would miss on the 15". Is it noticeable? Yes very slightly.
- Battery life the 15" wins. 16" has a bigger battery but e.g. the 14" is quite easy to still kill with serious usage and I used the non max versions which have better battery life.
- display an wider memory access SoC seems to increase the low and medium power usage a fair bit
- I got 4-6h on medium/high real development work use on the 14" M1 Pro
- I got 6-8h on the 15"
- given that the M1 Max benches I read are even 25% less than the M1 Pro Entry.
I'd say 15" 100% = 14" Entry 70% = 14" Max 50-55%
- Size of the 15" is perfect it still fits in smaller bags just so where the 16" wouldn't. It is a lot lighter than the 16" and the the thinness is much more pleasent on a lap or table for typing. If I could ask for something I would want the bezel to be thinner (Dell goes way further out) and there to be a very tiny fan inside. It seem thick enough to fit a very thin fan and then you just never have to worry like you might on a hot summerday outside in the sun.
- One limitation is the single external screen, I never plugged in more than one display as I got 34" on moveable arm at home and usually always one big 32 or 34" at work. If you do want or need multiple screens afaik the M2 is limited there, which is dump, along with only having the ports on one side. Also the HDMI is missing which I rarely used because my workplaces were very mac friendly (USB-C everywhere) but HDMI is much easier on conferences and random places you may need it or TVs. I usually have one of those cheap 30 EUR dongles for when I do need it but not often to carry that around with me.
My use were the 15" is imo the best (even if we'd assume it cost more) is
- software engineering dev work (docker, Jetbrains, browser, vscode, terminal)
- I do carry it a lot around on trains too
- I also like to use it in different places on the couch, garden, home office, office, hammock
- when I was still a student without much of a fixed work place, I would pick the 16" as it can serve for a bit of gaming multimedia and so on for which I got now a TV/ipad/PC anyway but the speakers and display at night for movies on the 16" is definitely a lot better. Speakers are still very good for a notebook and much better than any windows notebook I ever had in front of me but not the marvels that the Pro speakers are.
Performance anekdote.
I recently for work had to use a VDI(Virtual desktop environment). Log into Vmware Horizon Client then supposed to use Confluence, VSCode, Visual Studio ... in there. Boy that is like it was 20 years ago. So slow and laggy.
From that just to the Intel Mac was a worlds difference for me working in the VDI was just so horrifically bad that I did not understand how other people can work in such a laggy slow environment, where swichting between apps the way I do it in my normal workflow is just so slow, even scrolling and typing at times that it is just not an option.
Then on the Intel Mac you can at least work well. Then on the M2 you just go from a useable very good experience to amazing.
You only really appreciate how far we have come when you see that next to each other. Like the way I use my notebook just breaks down when things are as slow as on these virtual machines (2 slow server cores + 16GB + suuuper laggy graphics). But on the M2 you can start up a Game on Steam and then swipe out of it into some browser as smooth as butter without any lag whatsoever, something you cannot even do on windows or you unlock the notebook and it instantly ready as if it never slept and was still on.
The difference is quite stark and in all that amzing fluidity of MX Apple devices I actually feel no relevant difference between a 14" M1 Pro and an M2 15". But the 4 year old Intel is a lot slower and boy
