The reason Intel keeps using PowerVR in those mobile chips is because it's faster than Intel's own GPU while using less power.
Due to the vast amount of different hardware and software configurations out there, performance improvements won't necessarily apply to everyone, and may even be regressions for some.
Ubuntu uses Unity by default, not Gnome.
Do we know it's 64-bit? Some Atoms are artificially crippled to 32-bit-only.
And yet it's the most popular SBC out there by a large margin.
That means they'll have to go with Intel. I predict a noisy fan and a quadrupling of the price.
That's much more likely to be the case than whatever nonsense some PR person is feeding these journalists. Ubisoft isn't known for their optimization prowess.
Rebranding is widespread in the mobile (as in laptop) GPU market. The 7xxM is probably just a rebrand of the 6xxM series.
There are still plenty of single player-only or single player-mainly games being released. Two recent examples are Wolfenstein the New Order and Metro Redux.
No, some Atoms are x86 only, some are x86_64.
What makes you think they aren't providing drivers?
The RPi SoC has an FPU. It also has some limited form of SIMD.
Except for the GPU, which is more open on the Pi.
They don't mention where they got their first batch of chips. It's very likely they got it from some third party since Broadcom doesn't seem to deal in small quantities. When the 3rd party supply dried, they went to Broadcom and were probably told to get lost.
