The 14" MacBook Pros which have the M3 Pro and M3 Max chips are the successors to the 14" MacBook Pros that had the M2 Pro and M2 Max chips.
----------
The 14" MacBook Pro that has the 'base' M3 chip is a successor to the 13" M2 MacBook Pro. Both are conceptual descendants of low-end 13" Intel MacBook Pros that had only two USB-C (Thunderbolt 3) ports, back when Apple was segmenting the 13" Intel MBP line into two-TB-port and four-TB-port versions.
As such, the 14" MBP with the 'base' M3 chip has several upgrades over the 13" M2 MBP; some advantages over the M2 MacBook Airs.
- It got the M3 chip
- It got an upgrade to the mini-LED-backlit Liquid Retina display
- It got a HDMI port
- It got a SDXC card slot
- It got a MagSafe 3 port (present on the M2 MacBook Airs, but not on the 13" M2 MacBook Pro).
It still has just the two USB4 (Thunderbolt) ports, and just support for a single external display. If you want an extra USB4 (Thunderbolt) port or support for multiple displays, you need to get one of the M3 {Pro/Max} models.
The RAM options are the same as machines with the 'base' M2 chip: 8/16/24 GB.
It lost the Touch Bar.
