Do you have the base model or the 8 gpu core one?
Sustained performance is something I'm not actually 100% sure on. On the other hand if the game devs start giving the m1 attention (which I highly doubt) it would be nice to have a little more thermal headroom + the 8/8. And well the 3d hobbyist stuff is still pretty light for me but I'm aiming to be able to one day make some income from it.
I have the 8 GPU Core with 16GB RAM and 1TB SSD. Thermal Throttling only kicks in after sustained heavy duty load after around 10 Mins, and this is driven by tasks that load the CPU or GPU to 100% such as gaming and video editing. Even then the performance is only reduced by 10-15%. Given that this new MBA is around 100% quicker than the 2016 15" MBP that I am replacing then I am still up 85% on sustained heavy work load. If all you are doing is office documents / web browsing / Zoom Meetings etc then performance is no different to the MBP.
On the other hand the usage I'm looking for is mainly mobile text editing from sofa to library etc. Yeah the passive cooling would solve worries about the machine sucking in dust from a sofa etc. The touchbar is kinda meh, but the bigger battery and charger is something I definitely value.
I think this is an important point, dust typically is the no1 enemy of computers longevity, and to have a computer with no moving parts and does not suck dust in, as an advantage. Also fans can fail over time so that is one less thing to go wrong. Some may argue that MBP can run cooler than the MBA, and hence improve longevity, But my experience is with the A series chips in the iPads they last forever with no fan. Also compared to Intel Chips these M1 Airs still run cooler under load.
The MBP does have a larger battery but if the MBA lasts longer than I can stay awake for, which it does, then a larger battery does not really add much benefit.
I’m torn between the MBA and PRO and wondering if you describe the differences in screen quality?
I can only compare my MBA M1 screen to my 2016 MBP - I would say that the M1 Air has a better screen than my old MBP 15" 2016. The viewing angles are much better and text is pin sharp. All the reviews I have seen say that the only difference is the max brightness. I never set brightness to max indoors, and this is not an issue to me. If you live in country with a lot of sunshine (I live in the UK) and tend to work a lot outdoors then the MBP brighter screen may be useful.
