The thing is the Bulldozer / Vishera architecture its self is old. not as old Bloomfield but older than Ivy Bridge, nearly as old as Sandy Bridge.
Vishera came out after Ivy bridge, Bulldozer came out only 5 months before Ivy Bridge. Sandybridge is 18 months older than Vishera. If you put it into perspective, Bloomfield is older than Phenom II.
AMD have just done nothing since 2012 though as far as releasing a "high end" CPU.
And I have no idea what you're talking about as regards mobile chips? AMD ain't got anything, that's why it's stupidly hard (Impossible) to buy an ultra thin Laptop with AMD (Laptops that were available with Ivybridge) or even tablets (Again, available with Ivybridge) and even then, Ivybridge was 3 years ago now. Intel now have a full X86 PC in a flipping HDMI stick (With a year old mobile chip!)
And as much as Jaguar looks "good enough" it's awol in the market that Baytrail is in. Not to mention Intel have a new tablet CPU anyway that's in this tablet ;
https://www.microsoft.com/surface/en-gb/products/surface-3. That is like nigh on the perfect tablet.
As far as my knowledge goes, there's one Jaguar touch screen Laptop. Some Sammy (
http://www.silentpcreview.com/article1378-page1.html). In those same devices today we're getting Broadwell CPU's. I've used that Jaguar Laptop, unpowered it's 1GHZ on the CPU cores, powered I only ever saw it get 1.2GHZ. Was perhaps behind my Vivobook (When I had the SSD in) as not only did it come out afterwards, it cost more, lesser build quality, lesser performance. Buying it brand new, there's one left on Amazon, and it's 589 quid. You can get better Intel powered Laptops at that price with FHD IPS displays.
There was perhaps one AMD powered Ultrabook worth something ;
http://www.asus.com/Notebooks_Ultrabooks/U38N/overview/. This Ultrabook was expensive though, there was a time when the stock was going decently cheap ; 500 quid or so. But the CPU used to throttle a lot by reviews. There's nothing like this now though.
I'm quite open to the notion of buying AMD, but AMD makes it impossible for me to do so?.
In my PC I've got a 4770K, there's no AMD CPU equivalent (Just as there was no CPU equivalent when I had a 4670K).
I have a Surface 3 Pro Tablet, again, there's no tablet equivalent (Even ignoring the aspect ratio/resolution, I'd settle on 16:9/16:10 1980/X) with an AMD CPU.
I have an Acer Aspire S7 Ultrabook, again, there's no equivalent with an AMD CPU. This is my Laptop ;

Hell, even if I wanted a replacement to my Surface 2 ARM, there's no AMD CPU in a tablet with equivalent spec. That replacement could now however be the previously mentioned S3 none Pro.
