So I have a laptop with an APU and there has been some performance issues (it's not performing as well on benchmarks as expected.) A number of product reviewers have stated that it's related to dedicated memory but I don't think they have their facts right. Either way, I'd like to better understand.
When I pull up properties on the GPU I get the following:
Total Available Graphics Memory: 4326 MB
Dedicated Video Memory: 512 MB
System Video Memory: 0 MB
Shared System Memory: 3814 MB
(Side note: Total ram is 1 stick of 8GB RAM)
Now the reviewers were expecting that there would be 4326 MB of dedicated memory, not the 512 MB shown. And they suspect that's the cause of the performance issue.
My question is this: what difference would it make if, for example, I were to increase dedicated memory from 512 MB to 1024 MB? (or whatever... note, I haven't found a setting in BIOS that allows me to do this so I can't just test it as far as I can tell.)
Is there something about how it allocates RAM that would give it a performance boost with more dedicated memory? Because it's the same physical RAM either way.
For example, when I run firestrike and log RAM (GPU-Z) it shows dedicated RAM going to about 500 MB and shared RAM going to about 1000 MB or so (which combined is consistent with what my dedicated card uses).
