They are not "optimized" strictly speaking. Thousands of CUDA cores on them don't do ray tracing, it is done on a separate hardware which just happens to sit on

They are not "optimized" strictly speaking. Thousands of CUDA cores on them don't do ray tracing, it is done on a separate hardware which just happens to sit on the same chip. Add RTX cores to Threadripper crystal and you will get the same result.
