I've been playing around with Process Explorer on a laptop of mine with Windows 7, 4 GB of RAM, and an onboard GPU(ATI Radeon 6480g as part of the A4 APU). Oddly enough, Process Explorer reports 1.5GB of system GPU memory--all's fine here.

Also included is 512 MB of "dedicated" memory that I'm not aware of the origin of--the card does not contain dedicated memory.

enter image description here

I've seen a few oddities with this card such as Bitcoin miners seeing both the APU (which maxes out CPU usage) and a Winterpark device actually using OpenCL, and the fact that it's reported as dual GPUs to some legacy OpenCL applications.

With that said, playing texture or shader heavy 3D games will, as expected, increase the usage of the dedicated memory--the GPU system memory remains nearly constant.

The GPU should only be getting 512MB of shared memory, which is reported as 1.5GB on the GPU tab.

I'm currently not having problems except for weird resource reporting in some applications, so I'm only asking so far on the basis of curiosity.

@nodakai Not a dupe in my opinion, I'm aware of what Dedicated GPU memory is. The problem is that I'm sure I have none as the spec sheet specifies I have none, and dedicated memory is, by convention, not put into cheaper laptop integrated GPUs. That is why I am asking this question. –  hexafraction Jan 23 '14 at 1:00

1 Answer 1

  1. Are you sure that Radeon hd 6480g embedded in A4 is the only GPU on your system? Several high-end notebook PC's have a discrete GPU as well Control panel -> Device manager -> Display adapters

  2. You can try alternative system monitoring tools to gain more information. (Sorry, I don't have any Windows boxes right now)

  3. Btw, this is how those numbers are calculated

  4. What's wrong with your Bitcoin miners? OpenCL is an API for utilizing both CPU and GPU in an unified manner (but legacy OpenCL apps just assumed all the OpenCL devices were GPU)

This is a lower-end machine, definitely no extra GPUs there. Device Manager confirms this. The miners are probably just reporting the CPUs as GPus where the Winterpark is a real GPU. –  hexafraction Jan 23 '14 at 1:58
