Hello, Ive been wondering why certain programs will use the GPU's processor slightly when downloading large quantities of data.

 

Spotify and steam are where i notice the most usage of GPU resources during downloads then once its done goes back to sleep. Is this some decoding process? Are the downloads using the GPU to decode the compressed downloads? Im just curious as there has to be a legit technical reason but your first few pages of google about "GPU used in downloads" is very frustrating as most posts are just random BS.

By downloading in spotify do you mean strictly actually downloading stuff locally or just streaming in general? Also, are you using the UWP version of spotfy? The UI is hardware accelerated, it could be as simple as the GPU updating the seekbar visual. Should something as simple as that take up that much GPU usage? Probs not. Highly unlikely that any hardware decoding is active in this case.

Local download of 400 songs to my SSD, it seems like the GPU is used to decode the compressed data from some downloads. Its not hardware of application, no GPU use when not being used. GPU could easily be used for decompression of compressed data. whole thing lasts MAYBE a minute @ 180-200MBps. small 10-15% gpu usage spike then back to 0-1% once finished. Minimized windows each time so they are not displaying and bars/data.
