Sorry, got sidetracked and didn't get a chance to check back...

Cyborg has the basics right here... more details (not too many):
The A8 is a "Quad Core" CPU, with 4 GPU cores.
I'll try to keep this simple...
Specifically, the "GPU" is on the CPU, but the rest of the "Video Card" is built-in to the Motherboard.
It also uses SYSTEM RAM for the Video.
Unlike your R7 where GPU and Video RAM are all on the same card.
Your R7 uses it's own RAM (most likely DDR5).
(This is a "bottleneck", which is what slows down the APUs vs. a similar PC with a dedicated "Video Card".)
Now that you have an R7 installed, your BIOS detects that, and sets the R7 as the "Primary" and (more or less) ignores the APU's R5, and does not reserve any System RAM for the Video.
The APU's R5 is still useable, but not for rendering video on your primary monitor.

Ohh, almost forgot...
IF the definition of APU is: "GPU on the CPU chip".
That would mean most (all?) recent Intel CPUs are
technically APUs.
Although Intel doesn't use the term.

P.S. I re-did this a few times, tried to make it simple, yet more or less complete.
So if you want any more detail on this let me know.
