Neither is “great” on a GPU:
• Image optimization is still mostly software: JPEG, PNG, WebP. GPUs do not bring much to the table here at all, and consume a lot of power, which is likely to upset the hosting ISP of that cache node.
• Video encoding is better, but still average. NVENC (Nvidia’s encode Engine) has some quality challenges and limitations.
Further, doing this at the edge makes less sense: if you have to fetch the source material from the origin, do the heavy lifting centrally and store the results at the edge. Storing 4-5 renditions is cheap compared to GPU running costs here.
