also btw, keep in mind if you are after performance and want the best in thermals, the 4 thunderbolt model is alot different internally compared to the 2 thunderbolt model.
This is the internals of the 2 thunderbolt model
This is the internals of the 4 thunderbolt model
The 4 thunderbolt model have better speakers, better thermals, bigger battery (though the battery is very small in difference from 54.5w to 58w) and if im not wrong better microphones.
Additionally, the CPU in these devices are different in terms of their wattage. the 2 thunderbolt model is only 15watts vs the 25-28watts on the 4 thunderbolt models. This equals more performance, thats why the 2 thuderbolt model starts at 1.4ghz processor vs the 2.0ghz on the 4thunderbolt models
The better thermals is NOT just because of the 2 fans, but the chassis design too. If you are familiar with the 2012-2015 retinas, the bottom of the macbook pro theres 2 slits at the edges for additional airflow.
The 2 thunderbolt port macbook pro is more reminiscent of the macbook air. The intake and exhaust is all in the hinge of the macbook.
I hope this helps your purchase decision when it comes to the pros. I returned my 2020 macbook air due to the heat issues i was facing with the laptop. If you are contemplating a macbook air instead of the pro. It really depends on what you will be doing/your workflow. The macbook air is fine if you are using just for spotify, social media, emails, netflix. But thats it. Anything more it will start to heat up and the fans will kick in. High temperatures and loud fan noises is what made me return it. Now with how we are working from home due to covid-19, i noticed the computer start to stutter with just video call and safari and maybe my word application open. When I tried to screen share, the laptop just slows to a crawl with the fans at max speed and temps at 100 degrees.
If you really want the air, get the base model with i3, at SGD$1,449 for a modern 2020 macbook, its a good deal. the i3 version has better thermals compared to the i5. If you do pick the i5, its already at SGD$1,599. I would really recommend you to get the base model macbook pro for SGD$1,799. The thermals alone is worth it imo. Dont be fooled by the spec sheet of the macbook air with its 10th generation i5, that i5 processor performs worse compared to the 8th generation i5s found in the macbook pro due to the thermal constraints of the macbook air.
