B550 compatibility

I know the entire AMD society is cheering about the support for Zen 3, as they should be. Congrats! Although many people just glossed over it, I am here wondering why AMD decided not to make B550 compatible with olde Ryzen. It seems unfair to those who just want to upgrade their motherboard whilst having a 2nd gen Ryzen CPU. Does anyone feel the same way? I want to future-proof myself for the upcoming 4000 series CPU's, but also want to upgrade from B450. 

 

Anyone out there that has better knowledge of motherboard limitations feel free to throw in thoughts of why they are doing this. 

 

 

Cheers LTT community!

b550 should have twice the amount of rom storage than the b450, so we're more hopeful that it will happen. Many however think that ryzen 5000 might be on a new socket.

probably because they want to avoid limiting newer CPU support, who knows how many skus they still have planned and not planned.

Yeah I could understand that. I know the bios size was a factor in the X470 for Zen 3 but I think that a 32MB bios. ASUS X570 boards still support CPUs from Zen+ so it seems weird how B550 can't do the same.

Might be amd limiting the agesa that the manufacturer needs to make the bios, AMD was often bullied before by them, but with them winning market share they've gotten a bit more of a bite.
