What are the advantages/disadvantages of adding more threads to your cpu?

Would an i3 with 2 cores 8 threads, or an i7 with 3 cores 16 threads, perform better than the current lineup in multithreading?

Why does Intel only use 2 threads per core with hyperthreading?

What about GPUs? They're heavily focused on more cores. Why don't they add more threads through SMT?

>add 8 hardware threads to each core and add all these architectural improvements

Like rendering?

And isn't dx12 8 threads?

How close to an i5 6600 would an i3 6100 get if it had 8 threads in something like h264 encoding and decoding?

Would adding the extra threads even help, or is there no point?

Sounds like a good deal for doing small tasks in parallel like an HTTP server.
