Frequently asked questions
Are B550 and B650 motherboards compatible with the same CPUs?
No. B550 is an AM4 board, so it pairs with AM4 chips such as the Ryzen 5 5600 used in the B550 build. B650 is AM5, used here with the Ryzen 5 8500G. The two sockets are different, so you cannot move a CPU between them.
Which platform has the better upgrade path?
B650 is the current platform, so it is the one to pick if you want to keep the board and add newer AM5 CPUs later. B550 is last-gen AM4, which means upgrades stay within that generation. In these builds, the B650 board cost $150 versus $100 for the B550 board.
Why does the B650 build use 16GB of RAM when the B550 build has 32GB?
Same-budget builds shift money between parts. The B650 build spent $245 on 16GB of DDR5-6000 and $150 on the board, while the B550 build spent $220 on 32GB of DDR4-3600 and $100 on the board, which let it put more elsewhere.
Who should pick the B550 side?
Pick B550 if you want the lower median board price of $100 and more RAM in the build: the B550 build includes 32GB of DDR4 and the ASUS GeForce RTX 3050. It is the last-gen value route, not the current upgrade path.
Who should pick the B650 side?
Pick B650 if you want the current AM5 platform and DDR5. The B650 build here came in $7 less overall, using the Ryzen 5 8500G, the GIGABYTE B650 AORUS Elite and the MSI GeForce RTX 3050 LP, but with 16GB of RAM instead of 32GB.
