We can finally present to you the results of our extensive AMD B650 motherboard roundup. It's been a massive undertaking that took several months to test 35 boards in total, but it's finally complete.

Thanks for the review, that's quite a bunch of boards here.
This gen is insane, AM5 boards from 120 to 430 and only one chipset!
Looking at motherboards these days the mATX especially, when inserting a GPU those slots are not usable. I got a ATX board and from 7 slots only the bottom 2 are somehow usable. You have to leave some space for airflow on the GPU.
2,5 slots GPU need at least 2 full slots for airflow, this makes only for GPU 5 slots. And since I still use a Pci-E sound card that is the reason that made me buy an ATX board.

All better than the outgoing LGA1700 boards....
Was there any other testing of the boards outside of measuring the backside of the board at load?
Was there variation in performance when using the same RAM, CPU, and GPU? Was there difference in system power draw at idle and at full load? Board temp is really easy to mitigate (increase case ventilation) while other inherent board advantages / disadvantages are not.

Thank you Steve for the comprehensive review.
Just something I’ve noticed - I’ve been planning out a TrueNAS build recently and it looks like B650 boards have largely dropped ECC RAM support (which was sorta present in AM4 B550 such as Asus and Asrock). Was wondering what the state of AM5 with ECC is currently.
EDIT: turns out the Asus ProArt B650 has ECC RAM support, which fits with its target use as a workstation mobo. A few other forums point out AGESA issues that are yet to be resolved for DDR5.

Only two mini-atx? I was hoping to see something nice from Gigabyte there.
All ddr5 supports internal ecc, are you sure you need to spend extra on external ecc as well?
Good question. It's for a NAS that stores master media files for clients - RAW files and A-roll / B-roll video - so the data's pretty valuable. Perhaps even unbuffered non-reg ECC (which is the limit of consumer AM4 support) isn't good enough for that application. I've been quite disappointed with the off-the-shelf Synology and QNAP offerings, and was investigating AM4/AM5 custom build options with TrueNAS before heading into Xeon territory. ECC support was one of the selling points of Ryzen consumer CPUs, but 12th/13th gen Intel seems to have opened up ECC support as well - although only with workstation (W680) chipsets.

This is an absolutely incredible article. THANK YOU for having written it!!
Now, please inform me... Is there any point buying a board now if waiting for Zen 5 (8xxx) processors to come out? (Since the AM5 boards are supposed to be compatible with them)? Thanks!
