Personally I wasn't expecting there to be any cases where the 7950X3D was slower than its non-3D counterpart, but there are a few. These seem to all be lightweight esports titles so presumably the amount of cache and memory they use is so minimal that losing the frequency is actually a net loss. Increasing the clock speeds on the other CCD didn't seem to really do much, but maybe AMD can somehow optimize the 7900X3D and 7950X3D on a per game basis?
