Threadripper's not dead. Far from it.

Would anyone actually need that many cores though in the standard HEDT range?

HEDT mostly workstation so I'd say yes. Especially if they're rendering.

But isn't a GPU still quicker and more cost effective? A 64 core can't be even remotely affordable.
Depends on the workload basically, you need a >98% parallel workload to really make use of a GPU and even then if it's non-uniform or branchy like compilation or simulation a CPU would usually do it better. Modern CPUs have lots of specialised units for certain types of calculation that GPUs don't necessarily have and vice versa.
For 96-98% parallel workloads you can still get a good 30-60% speed up going from 32 cores to 64-cores. For 95% parallel going from 32c to 64c gives upto a 25% speed-up, going up to 4096/infinite cores you'd only get a 60% speed up from 32c but often with GPUs those cores are several times slower per "core" so it's not worthwhile when your workload is still this serial(5%).

Depends on what type of rendering. You can also still use a CPU AND GPU to render something as well. So still helpful.
Or now that I think about it, if you had two renders, one could be loaded onto the GPU and the other the CPU. That would be quite something to.
Let's be real you could do pretty much anything without a care in the world with 64 cores^_^
