I think that it isn't just AMD that is going to have to do this. Once upon a time, a new process node got you huge performance increases by doubling your transistor budget. A new generation processor was SO much better than a last gen one that the old gen simply wasn't worth much any more.My guess is
$449 12-core R7
$389 10-core R7
$329 8-core R5
$279 8-core R5 Zen5 (9700X refresh)
Basically a small reduction in $/core, nothing crazy.
This pricing pushes people with less than 300 dollars to buy last gen 8-cores, which is what AMD really wants.
Today, we look forward to .... 10%? 15-20% optimistically?
Perhaps the ONLY way to make this make sense for an OEM is for them to keep selling the product for a much longer time period after the release of the previous gen ..... and to sell multiple generation chips on older (and less expensive) architectures and nodes for the lower cost.
