Could a GPU act as a southbridge to control mouse movement?

post #1 of 4
Thread Starter 
I was wondering if a GPU could act as the southbridge interpreting mouse input to the northbridge. The idea would be for the GPU to interpret mouse movement to increase the efficiency of preloading new textures or in tesselation loading. If the passthrough would not work could you split a usb mouse to send to both the gpu and the southbridge.

Uhm...,

I think I see where you're going with this.

Yeah, I don't see why it wouldn't be possible if a GPU were to be designed for it. There currently aren't any that are though, of course.

The question though is if the benefit from doing so would outweigh the added latency and processing overhead. Also, in a more realistic approach, would it be a cost-effective way to increase performance?

Those questions I have no answers for.

Wow, cool idea. I don't see it as a huge performance increase though, probably not worth the effort to implement it.
