I think the mobo makers really disliked releasing AM4 BIOS updates so now they are charging ahead of time for that "incovenience" with AM5.
I have always said and thought that ram is ram. Remember when they had/still have AMD specific ram? Then the B450 fixed the ram issues. Then AMD said the B350/X370 boards would not support Zen 3. Then they issued bios fixes so that there were no memory restrictions with B350/X370 motherboards. Then they updated the AGESA bios to support Zen3 on the original AM4 motherboards.
I know there has been a number of trust issues violated. Too many make excuses for AMD. Bios updates take forever but are always fixed. Intel says, don't worry about it. When you buy your next CPU and motherboard, those issues will be fixed in the next generation.
Quick question, did I pay too much for my Asus B450-F @ $90 brand new? Did I pay too much for my top of the line MSI B350 Carbon Gaming Pro motherboard @ $80 4+ years ago?
Lastly, I like that AMD supports motherboards for many years and many generations. If Intel 4 (7nm) hits above it's weight. Remember I said this is Intel we are talking about. They don't like to lose for long. Will AM5 justifiers of $250-300 motherboards look foolish if Intel wipes the floor with AMD moving forward? In 2 years will Intel be 30% above AMD in IPC with the same or similar core counts? If so, there goes justifying the inflated costs of AMD motherboards.
On the positive side. AMD has always been masterful at pricing their products up against better or slightly better competition. When AM4 was first released all the reviews raved about the cheap AMD motherboards and the entry point for AM4 systems though inferior offered a lot of value.
I speak for the computer market. AM4 CPU's are selling great right now compared to the AM5 Zen 4 processors. I won't even start a GPU argument and question the logic and reasons for AMD pricing. Like why is the 6800xt not $300 today?
