GPU designs will have to change, evolve. The leaks/rumors that both AMD and Nvidia are goin the chiplet route and are already prototyping designs point to that direction, but it remains to be seen if they'll be able to solve the latency problem derived from going this route.
Once they solve that, the future could be modular GPUs with several parts designed for different tasks all interwoven together to maximize efficiency and performance.
