Kaveri Hybrid CrossFire: The A10-7850K & A10-7700K With R7 240 & 250 ReviewPosted on 2014-02-27 11:50:06 by Thomas De Maesschalck
The term “hybrid” in Hybrid Crossfire is coined because it is a hybrid amalgamation of “discrete-class” integrated graphics on the APU with a discrete graphics card. The logic of CrossFire is still retained in Hybrid CrossFire – you should pair two similar graphics processors to scale extra performance through synchronisation and joint GPU processing. In the case of Hybrid CrossFire you aren’t dealing with only graphics cards like you would be withnormal CrossFire, but instead GPUs so it can be problematic, though the objective is still to pair similar parts. AMD does set out some official recommendations for which R7 series GPUs you should pair off with each Kaveri APU – we will detail those recommendations on the next page. A final thing to briefly mention is frame pacing. AMD have released a driver fix for frame pacing which effectively fixes the problem of delayed “runt” frames. In our case we have enabled the frame pacing driver but we lack the equipment to show you how effective this frame pacing driver is. However, we can point you to PCPer who have investigated the driver fix to show that it does solve the problem and offers identical performance to what you would get with the frame pacing setting turned off.
