Moving from an aging intel macbook to a modern m2 is a night and day difference, the passive cooling won’t limit you for most dev tasks you throw at it.
As for your throttling, I experienced massive throttling issues on a 2018 macbook pro 15”. Started out of the blue, and was so bad that I couldn’t even do 15 minutes of video meetings before audio and video lag and break ups set in. Lived with it for weeks, until I tried resetting the SMC - which worked like magic! Machine returned to its former glory. Worth a shot in your case as well.
Other things to try if the machine is aging, is to open it up, clean all the dust, and reapply thermal paste. It might be all clogged up depending on where you’ve used it. Aging thick thermal paste can be pretty bad as well.
