True, didn't consider the board price. On Z790 it looks like a jump from $180 for the cheapest DDR4 board, to $210 for the cheapest DDR5 board, so $30 increase. I think it's a larger difference on Z690s. Well... $130 for the cheapest DDR4, $150 for the cheapest DDR5. Though that's really naked looking boards, the decent DDR5 ones look to be $190+.
Your comparison seems slightly adjusted due to board differences between DDR4 and DDR5 models. The updated list reflects the price change when switching from the B660 to the B660M model. Prices now account for shipping, taxes, and any available discounts.
