But they already have the cat cores to cover the low end and low power segment, both on desktop and mobile/laptop. That design is generally acclaimed for being good for it's segment, and the uArch is quite new.
If they are aiming at higher performance mobile/laptop CPUs than what the cat cores provide, then those new CPU cores can be used on the desktop too. I.e. same as Intel does with it's Core uArch cores. So if AMD can use the new Zen cores on Desktop too, we're back to my previous estimate/guess.
It seems we dont disagree quite as much as you think
😛
Here is my expectation and why;
I believe Zen will be a "medium" core, between Jag and the BD family. I believe it'll scale quite well, but it'll be more aimed at the "wider" audience of consumer computing; ie. Not high end desktop, not tabs, and not any niches. It'll be a chip for most standard notebooks 11.6"-15.6" and have a desktop presence akin to the one the G3258, i3 line, 860K and 6300 have now; great CPUs for those on a budget (ie. Most folk).
I do not see them going for ultra mobile (tabs mainly) because well... Look at Temash and Mullins (wait does anyone even remember those things?)
I do not see them going at Intel's flagship because the R&D budget, lithographic technology available to AMD, the time, the tools and market share available to AMD doesn't really allow them the ability to get at Intel's flagship performance without running high on TDP/missing an iGP/really some weakness. Something has to give.
I definitely think Zen will be an interesting, ambitious and unique design. I just don't see it being a "ultra low power" or "ultra performer" chip. I think the approach is more "jack of all trades, master of none" to snag more affordable consumer market share from Intel in the most common form factors (cheap desktop or standard laptop.) I also think Zen will be aimed to be AMD's only x64 chip, tossing out the BD and Cat family.
Those are my expectations and reasoning. If you disagree, thats fine
🙂 If you like, provide your expectations and reasoning and where I may have gone wrong.
