Comparing the plain M3 MacBook Pro to the M2 Pro MacBook Pro, it looks like the plain M3 chip is faster than the M2 Pro in single-core (around 3000 vs around 2700), but slower than the M2 Pro in multi-core (around 11,700 vs around 12,500).
If the base 14" MacBook Pro M3 with 8/512 is $1,599, and an Apple certified refurb 14" MacBook Pro M2 Pro with 16/512 is $1,599 too, is the latter still the better buy?
1x extra TB4 port, capability to drive 2 external monitors, extra RAM will give the edge in most workflows.
No brainer to me.
