Is it worthwhile upgrading to the new MBA? I've currently got a 15" 2016 MacBook Pro (touchbar)
Processor: 2.6 GHz Quad-Core Intel Core i7
Memory: 16 GB 2133 MHz LPDDR3
Storage: 250gb
Graphics: Radeon Pro 450 2 GB; Intel HD Graphics 530 1536 MB
I dabble in statistics & data analysis, usually in excel or SPSS with large datasets. Wanting ensure it will pump through analyses.
I have the same 2016 MBP with 16 GB RAM that I replaced with an M2 MBP with 96 GB RAM when it got sluggish due to limiting RAM. Your MBP was Apple's high end laptop and you are considering replacing it with Apple's low end laptop. Yes, despite being the low end the MBA chip is modern and stronger than your 2016 box, but you should be very careful about downgrading to an MBA. Literally everything about the MBP except weight is better than the MBA: display, speakers, memory bandwidth, available RAM, brightness, ports, etc. for just 10% more money if both boxes were base M4 at 32 GB RAM.
IMO 32 GB RAM (maximum available on an MBA) is the
minimum you should be at for a good life cycle and smooth operation. Apps like SPSS take good advantage of RAM and OS/apps increase how much RAM is beneficial every year. If you stay involved with modeling you are likely to see usage of AI components becoming more prevalent, which totally gobbles up RAM.
An MBA is a very good value choice, but it is a lower end computer. Personally the twice-as-bright display brightness alone makes the MBP the only computer I will choose personally. Also I really like the available nano-texture display on the MBP, but that is just a bonus.
You should compare the MBA to the MBP yourself at an Apple store and also decide how much RAM your finances can allow. If I was dabbling in modeling via SPSS and the like I would buy
more than 32 GB of RAM for any kind of 5+ year life cycle.
