AMD has made it very clear they will not be using this for the desktop, nor should they. Sure, people will whine, mainly because they like to, but this would be a worthless product if they didn't limit the scope of it.
It's not going to perform as well as a Piledriver core, which will remain their high-end desktop part. They couldn't do it, and didn't try. They are still stuck on 28nm, with a bad CPU design, so they just want to focus on a small portion of the market and get it right. So, they no doubt sacrificed things that are not needed on the intended platform, like a lot of PCI-E lanes, and high clock speeds, to maximize performance per watt in a limited scenario. It was the correct move.
The Puma based Carrizo-L will also be using that platform, which should give you a clear indication isn't not going to be a higher-end desktop platform.
AMDroids have to realize, AMD can not make a competitive part on the desktop. Not in 2015. They aren't going to go out of business trying to cater to people wanting to kill the evil Zargons, who also want an AMD CPU. They can't do it, so aren't trying. They feel they can do well in the segment they are targeting this processor at.
