Memory Scaling On The AMD Kaveri A10-7850K APU

AMD’s Kaveri APUs bring support for Hybrid CrossFire. With Kaveri AMD is now naming the system “Dual Graphics” but it is essentially the same thing. Below you can see how the Dual Graphics performance scaled with faster memory. Please see our dedicated article to Dual Graphics if you’re interested in reading more about it.
We observed similarly impressive scaling with hybrid crossfire as we did with iGPU gaming. If we were to have achieved the “best” performance we would have had to match our R7 250 with our APU in terms of memory speed – so 2400MHz on both (1200MHz actual). Yet our R7 250 was only capable of 2000MHz (1000MHz actual) so the results weren’t as good as they could have been. All things said the scaling is still impressive ranging from 10% to 20%.
Just like with the APU memory scaling we saw slight increases in power consumption with hybrid crossfire. Removing bottlenecks associated with memory means more performance but more power consumption as a result. However, the increases are tiny so there isn’t much to complain about.
