Dual Graphics, APU and AMD Graphics card (separate), or CPU w/ AMD Graphics card?

[Guest]

If you don't/can't use AMD Dual graphics with your APU and discrete graphics card, what will happen to the extra "compute cores" in an APU-Graphics card setup, like an A8-7600 w/ an R7 260X. Will the APU still perform better than it's CPU counterpart? (FX-series vs. AMD APU)

[KemoKa]

No, what happens is the GPU cores in the APU turn off and let the 260X take over. You're left just using the CPU.

[Atmos]

Despite AMD's terribad chat saying otherwise, 

 

only the R7 240, and R7 250 work with dual graphics in modern APUs.

Nothing, they sit there being useless. It would be really cool if a new API was developed that could use those compute cores for something else if there was a discrete GPU in the system.

As said above, they just sit there. I did find a user-made patch for the OBS streaming software that will use the iGPU, similar to Intel's quicksync, but that's it.

If you have a second monitor, you can plug it into the onboard graphics and free up a small percentage of your main gpu.

Edit: depending on the architecture will determine how the compute cores compare. But sure myself. My A10-6800 performed ok, but cpu heavy games like Starcraft2 would start to lag later in games.

Doesn't OpenCL do that?

how about with the Kaveri architecture (A8-7600 or A10-7850K)?

the Kaveri is 10% faster than the A10-6800K in terms of IPC per clockspeed

 

it should be fine with most games but games which depend on the CPU more like Arma 3 will be a struggle to run

 

the 860k is based off the A10-7850k minus the iGPU side and it OC like a beast 

 

the better combo will be to pick the 860K and a R9 280 

 

it was the combo used in Linus Scrapyard Wars Thrift Machine vs off the shelf new parts build

so it seems if I pair an APU with a graphics card that can't do dual graphics, the graphics in the APU doesn't really matter. then where's the benefit of an APU with a discrete graphics card vs. a CPU with a discrete graphics card?

It's easier for OEM's to buy APUs from one manufacture that brings support for both serial and parallel workloads instead of having to buy the CPU and then the GPU from different sources. HSA support is coming with Carrizo and that will be the first time that the iGPU will justify itself as part of the CPU even if you have a stronger discrete GPU.

that seems to be an industrial benefit. what about when people use a computer for gaming, video/photo editing,CAD, rendering, animation, etc. at home?

in the real world it gives a better user experience because things like thumbnails load faster as well as other things, apus aren't recommended for gaming, i used to have one.

are you saying that usual internet usage will benefit from the APU but not gaming?

[blackadder]

no, between intels igpu and amd apu the apu can play more games and give you a slightly faster experience for very things. As soon as you get a dedicated gpu this changes. The apu/igpu graphics gets turned off and you use your graphics card.

[Guest]

Another question about crossfire. Say I have an AMD A10-7800 and two r7 250s. could I use crossfire on the  r7 250s and dual graphics with the AMD-7800 at the same time to have virtually three r7 250s?

Isnt it possible to for example run another monitor off the iGPU? And cant you even render with the Intel GPU while gaming for example?

UPDATE: About to get a new laptop with Dual Graphics built-in (A10-7400P + R7 M265DX). So which games can benefit from Dual Graphics? (Obviously not every game right?)

honestly don't have a clue, i would look up how the r7265 does in the games you want to play and see if that is good enough for you.  the 265 is going to be doing the lion share of the work in games.

what websites do you recommend to check how well certain graphics cards run certain games? I just don't want to find jargon websites,adware, etc.

Last question, I just read an article on Dual Graphics and in the end they say Dual Graphics has a bigger impact on laptops than desktops. Do you guys think so? And what do you think AMD should do with Dual Graphics to make it better other than driver updates?
