ASRock B650M Pro RS vs Gigabyte A620M S2H: Comparison
What is the difference between ASRock B650M Pro RS and Gigabyte A620M S2H?
On memory slots the spread is 50%, ASRock B650M Pro RS 4 against Gigabyte A620M S2H 2, so ASRock B650M Pro RS takes it. ASRock B650M Pro RS also leads on m.2 slots, 3 on the ASRock B650M Pro RS versus 1 on the Gigabyte A620M S2H. Add max memory to that, 256 GB on the ASRock B650M Pro RS versus 128 GB on the Gigabyte A620M S2H, and the pattern holds. Board width is not the same on both, 244 mm on the ASRock B650M Pro RS versus 230 mm on the Gigabyte A620M S2H.
Which should you buy, ASRock B650M Pro RS or Gigabyte A620M S2H?
Buy the ASRock B650M Pro RS for the most affordable current-generation AM5 builds, though it is not built for anyone who wants Wi-Fi included out of the box and builds that want a PCIe 5.0 x16 GPU slot. It also earns its place with builders who don't need a PCIe 5.0 GPU slot or built-in WiFi. The Gigabyte A620M S2H is the one to take for first-time builders who value tool-free PCIe installation, though it is not the pick for anyone wanting a second M.2 slot or factory wireless and overclockers, since A620 does not support CPU overclocking. The same goes for budget AM5 builders who want BIOS flashback convenience without paying for a B-series chipset.
Where the two are identical
Everything else lines up. Form factor, platform, newest cpu family supported, oldest cpu family supported and wi-fi onboard read the same on both, so those are not worth weighing. They match on 5 further specifications as well.
