This article is would be more appropriate for an April Fool's joke. “20-100 times the power, yet consumes barely a milliwatt"? What a joke. At best, it will consume 1mW when mostly idle and thus power and clock gated for most of the time, not when at 20-100 times the current performance.
The PC enthusiast world seems fairly clueless about what is going on in the embedded world judging by the comments post here and elsewhere and judging by the one-time fairly reputable Tom's posting garbage like this.
Mobile chips are about performance per milliwatt and cost to manufacture (die space, etc.) and not mostly performance oriented like for Desktop PCs and even laptops. Here's the breakdown of how the embedded GPU industry looks:
ATI: Sold their mobile graphics division to Qualcomm a couple of years ago. Since then, afaik, Qualcomm is keeping the technology in house for themselves and not licensing out. Only a few companies sell a part with previous generations of this technology that licensed it before the Qualcomm deal was finalized. AMD CEO should have got b-slapped for this or not starting another mobile graphics group as much as anything.
Nvidia: Does not license out their mobile GPU afaik. They keep it all to themselves for their own ARM SoCs. Dumb move in my opinion as their largest expertise is in graphics and they could make alot more money if they licensed it out. But, I'd guess it is behind Imagination/PowerVR in performance per millwatt so perhaps that is why they don't license it as it may not be very competitive.
Intel: licenses from Imagination/PowerVR for the lower end Atoms.
ARM: Licenses a GPU which is behind in Imagination/PowerVR is behind on features (latest OpenCL, etc.).
Imagination Technologies PowerVR: The dominant player in the embedded GPU market, at least of those that license it out unlike Qualcomm and Nvidia. Apple, Samsung, Sony, HTC and most other phones and tablets that don't use a Qualcomm or Nvidia chip use Imagination Technologies. That said, Nvidia and Qualcomm parts now make up a significant chunk of the market.
Others: There are a few other players competing in the embedded high end but for now they are dwarfed by ARM Mali, PowerVR, and the non-licensed out technologies of Qualcomm and Nvidia.
