I have a system with an Intel Core i3-2120 CPU, which has Intel HD Graphics 2000.

I have a need for an application which puts load on the GPU (HD Graphics 2000) but does not draw to the screen, i.e. does calculations on the GPU but just discards the results afterwards.

Does anyone happen to know if such an application exists?

On the Core i3-2120, the GPU and CPU portions of the chip are supposed to be separate. I'm looking to try to prove that conclusion on my system. The reason for this is that I am working with hardware-accelerated transcoding and media streaming. I want to know what happens to the overall system performance while it is in the worst case scenario with the GPU pushed to 100%.

Can you tell us why exactly you'd want that? What is your real problem you need to solve? – slhck Nov 29 '12 at 17:03
The idea here is that: If I completely load down the onboard GPU (99%-100%), how does the CPU/overall system react? The CPU and GPU should be theoretically separate on the processor, but I would like to be able to confirm that. – Brutick Nov 29 '12 at 18:18
Maybe you can edit and rewrite your question to state that? This might give you better answers, and we generally encourage users to ask the actual question instead of the attempted solution. Thank you! – slhck Nov 29 '12 at 18:21
@slhck Done, thanks for the guidance. – Brutick Nov 29 '12 at 18:34
Run a benchmark tool and minimize the GUI. Now it does what you want. – magicandre1981 Nov 29 '12 at 19:39
