Amd Dual Graphics actually good?

[Guest]

Hi,

 

sorry, i didnt know whether i should post this in the graphics card subforum or laptop subforum,

 

Anyway, i have a laptop which uses dual graphics (cpu integrated+dedicated) and i dont know if that adds frames or loses frames.

anyway the specs are

 

AMD a10 5750m

AMD Radeon HD 8650g  (the integrated gpu)

AMD Radeon HD 8750m

2*4gb ram

 

People may say its obviously dual graphics but on this comparison it shows the 8750m is faster which dont make much sense to me

Just test it yourself only then youll know for sure.

My dual graphics was a pile of shit so my vote is no 

it's bad

It all depends. You should benchmark it with the games you play yourself.

 

For the dual graphics to be able to work most efficiently, the system has to be able to predict what the next frame would look like. But in games like FPS, you're jerking the mouse every which way rapidly and there's no telling what the scene's going to be like until it's time to render it. In those situations the dual graphics can't really do much. All the work it would normally do is wasted. Then again, for a very static view with not that many moving object, for instance map-clicker games, most of the scene can easily be pre-rendered. Which should work fine. Even then a lot depends on the game developer and the ways they enable pre-rendering by dual graphics.

 

Generally speaking, those static benchmarks aren't that great at telling which GPU is better in real-world work. Think of comparing two cars and their capacity of transporting lots of stuff if the only test you ever run on them is a quarter-mile drag race. That one test alone yields nowhere near enough information for it to be usable. You didn't want to know which setup fares better in Passmark G3D, did you? You wanted to know which is better for gaming.

Passmark is shit, it doesn't measure SLI or Crossfire correctly, so it's probably the same for dual graphics (essentially just Crossfire between an integrated and dedicated GPU).

 

Dual graphics almost certainly gives you more frames per second. The question is whether the frames are delivered in a smooth manner or in starts and stops with microstuttering.

Download 3dmark 

Well i just downloaded 3dmark, well at least attempted to but it does not work at all. For 1. I do not know if it is visual effects but the 3dmark constantly blurs out and i have to highlight stuff with my cursor to be able to read it. 2. I keep trying to run the demo benchmark, Tried 3 times, but everytime it fails and i dont even get to see the demo, nor get a score.

Thanks for the response, and yes i did want to know which is better for gaming. I mostly play fps games like csgo and overwatch so dual graphics is probably pointless in that case.

So is it always better to keep dual graphics on for the extra frames or does it all depend on how the frames are delivered?

I just went into AMD Catalyst Control Center and looked at the options for  AMD Radeon Dual Graphics and it shows this when it is enabled

But when its disabled, it shows this

Surely it is supposed to disable the apu right and use the gpu?
