Valve isn't complaining. It's an ex-employee of Valve who is.
It has both HDMI and composite. They just combined the analog audio and video jacks into one.
It's more than enough for playing video games, if they are made for it.
I don't think they will jump directly to ARMv8 because of the price point. Unless they wait 3 or 4 years for their next update, I don't see ARMv8 SoCs being cheap enough to use.
There's nothing stopping you from running other operating systems on the Pi. There are plenty of them around and you can write your own if you want, all the necessary documentation is available, or you can just look at the Linux source code if it's not clear enough for you.
They license ARM cores from ARM. They use their own AVR cores in their AVR microcontrollers. That's obviously what the parent was talking about.
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.
