Heh, what's with the last generation APUs AMD? Those look like 28nm Stoney Ridge processors (Excavator) to me. Still, maybe AMD can sell them for $30 for these low end devices.
APUs have generally lagged a generation behind, it's 12nm. Not sure why they went 12nm instead of 7nm, maybe they are wanting to do an IF APU but it isn't ready yet.Quote:

It would appear that Excavator is now the Atom equivalent. Die size wise how would Zen and Excavator compare at the same process size, anyone know? A pity they are just re-rolling 28nm chips, it would have been interesting to see if they could improve the design.
....its 6 watts which is pretty amazing for 28nm tech also consider the graphics performance. Question: would you pick those or a celeron?Quote:

I suppose it all comes down to price.
AMD doesn't seem to have anything in the bottom end of the market netbook wise and the lack of AMD there has really sucked the life out of them. I cant believe how much money it takes to get to an okay basic machine nowadays.

It's pretty obvious that AMD never planned to fab a smaller Ryzen APU than Raven Ridge, and the dual core/SMT + Vega 3 version is already a massive cutdown of the full die (which let's remember is quad core with Vega 11). There always comes a point where it's no longer commercially viable to salvage for a cheaper part. So if they've got a lowest viable price for Raven Ridge that's too high for the extreme budget market, and a load of surplus Excavator dies kicking around, why not reissue them? Getting a few dollars each for that silicon is better than it going into landfill (or whatever happens to waste dies).
As to why not 7nm? Well, it looks like the APU range is designed to be running one process behind the desktop range - the Ryzen 2000 APUs were 14nm vs the 12nm desktop CPUs, and the Ryzen 3000 APUs will be 12nm while we expect the desktop 3000s to be 7nm. I guess that should mean we see 7nm APUs in a year or so for the 4000 series...
As someone who had to do this (and is currently in the process of having a new motherboard delivered, because the ASRock A320M Pro4 has driven me up the wall by this point in time) I should point out that they DID want those back. It seemed to me that AMD were quite unhappy with people who would just keep them and threatened not to offer such "kindnesses" in the future for said people. I was about 2-3 days over their time limit to send it back, but I did send it back, so their wrath was tempered...Quote:

Maybe - just maybe - they stripped them off the packaging and rebranded them as the A6 9220C and A4 9210C... ;)Quote:

Look, I was (am?) somewhat sleep deprived, but I was also under the impression that the USED chips aren't something AMD can repackage and sell without mentioning that someone already used them to transplant a BIOS out in the wild. (passing inhouse stability tests or otherwise)Quote:
