APU + GPU in Non-Crossfire for Rendering

[Evanair]

I have been pondering this a while now and have yet to find any information helpful via google.  I am curious about the ability to leverage the currently disabled graphics cores on my APU to increase rendering performance in Premiere.

 

I am currently running a A10-7850k on an AsRock a88x chipset with a cheap NVidia 750TI card for CUDA cores.  With the release of OpenCL, I was thinking about putting in a AMD based GPU, but only if I could also enable the APU graphics cores (there are 500-odd cores sitting dormant).  AMD Dual Graphics supports a R7 250 card, one of which has 4gb of GDDR5 on it, and I'd have to boost my ram to 32GB of 2400mhz to help out the APU if I did this.

Anyway, lots of rambling aside, is this possible?  I don't (unless it actually helps) want to enable Crossfire, I'm more interested in gaining the ability to use Multi-GPU via the APU/GPU to speed of Aftereffects and Color Correction in Premeire/Speedgrade.

 

Thanks in advance if anyone has any prior knowledge on this.

Yes, it can be done and you don't need crossfire. The difference in rendering performance in premiere would likely be minimal though.

Almost completely sure it is not, I tried something similar to this, and it would not work in any sort of tandem when I tried, I would recommend to try for a CPU upgrade to a higher core count FX or INTEL equivelent as to not waste CPU die space

It will work, but the cpu is too slow to take advangtage of the faster gpu. Id stick with the 750ti for now until you get a much better cpu. You don't need that fast of a gpu for premiere.
