This may just be too obvious for you to mention, but GPUs only work well for (massively) parallel tasks such as matrix multiplication.

Of any day's computational workload, only graphics, (parts of) ML, and maybe space heating masquerading as financial innovation are amendable to be run in such a fashion. And those workloads are, as far as I can tell, already being run on GPUs (and similar) almost universally.

So I don't think there actually are major workloads that will shift away from Intel to GPUs in the near future?
