      True huge page support depends on Vega hardware (it supports up-to-4-level page tables while previous HW is limited to 2-level) however Christian made changes to the fragment logic to improve behaviour on large-footprint apps with earlier HW as well.

      The difference is nuanced - in both cases the idea is to allow one GPUVM TLB to cover a larger area of memory in order to reduce TLB thrashing - and won't make a lot of difference under normal use, but apps performing intensive random access across a footprint bigger than the TLBs can cover with small pages can show a useful improvement.
