P Suffix (Pro / Performance): Generally represents a higher-tier or feature-rich board within a lineup (e.g., Aorus Pro-P). It usually features stronger power delivery (VRMs) for stable CPU overclocking, better cooling/heatsinks, and sturdier build layers.
K Suffix (Value / Kompact / Entry): Typically denotes an entry-level, cost-optimized model (e.g., Prime -K). It is built to be budget-friendly with basic features, fewer expansion slots, simpler audio/LAN choices, and lighter heatsinks.

The Amazon listing for the MSI PRO B550M-P must have photos from pre-Gen3 motherboard.
It's description lies and says it has 4 DIMM slots while the photos of the board clearly show it only has 2 DIMM slots.

GIGABYTE B550M K AMD AM4 Micro-ATX Motherboard [amazon.com] $69.99

Gemini AI summary gives the edge to this MSI board.

MSI PRO B550M-P

Pros: Features EZ Debug LEDs for easier troubleshooting, solid memory boost architecture, and stable everyday performance for Ryzen 5000 series processors.

Cons: Basic entry-level VRM cooling and limited advanced enthusiast tuning options.

GIGABYTE B550M K

Pros: Budget-focused pricing, adequate baseline slots for standard components.

Cons: Often criticized on community forums like Reddit for sparse rear I/O choices, weaker fan control headers, and a more basic BIOS layout compared to MSI equivalents.

Hey look a "cheap" motherboard. First dead give away is the two memory dimm slots. Unless it's a mini ITX motherboard I would avoid motherboards like this. Better to have room for expandability than not.

The photo is wrong... The description isn't... MSI product page also says it's 4 slots

Perhaps the most noticeable one is no ARGB header on the ARGB... And I must say adding RGB does make my case look nicer

Considered this one, but spent $5 more to get the MSI B550M PRO-VDH WiFi. Mostly because of the well, the wifi.

The MSI B550M PRO-VDH WiFi is now available at the same price ($74.99) as well, for those who are interested:
