How does an APU work with a dedicated GPU

Just wondering. If you have an APU (I have a 7700k at work). What happens when you have a GPU installed? Does the graphics part of the APU switch off? Is it wasted? Does it do CPU calculations instead? Does it share workload with the GPU? Thanks.
 
so if it's often simply switched off. Why don't AMD make "pure" CPUs for us gamers who all have GPUs? I believe ZEN is also an APU?

As above some can work together but it doesn't work well at the moment.

AMD still make conventional CPUs, like the FX-6 and FX-8 range (AM3+). Also there are some non-APU chips for the FM2+ platform (Athlon X4) which are a decent budget choice especially as the motherboards are peanuts.

Zen will be CPU and APU.
 
I think the integrated graphics portion of AMD's APUs can be used for applications that use OpenCL even with a video card installed.

Pity barely anyone uses OpenCL for anything though.

AMD's new Zen CPUs are coming in APU and pure CPU flavours. They just stopped making new pure CPU parts as even an 8 core FX chip based on Excavator or Carrizo (i.e. the cores their current APUs use) would still be terrible.

Now that they're making a CPU based on SMT (instead of CMT) and using a process node similar to Intel's they should be able to compete. Well I bloody hope so anyway
 
Excellent, that's a big improvement over the older "hybrid graphics". Thanks to D3D12 it sounds like (which is thanks to Mantle ;)).
