when you make it less dense, it can clock up higher, but you will have fewer cores per mm^2
AMD went with both approaches, where their hybrid CPU will have densely packed low speed Zen 4C cores and some high speed Zen 4 cores to boost at the highest frequency
E.g. new Nvidia GPUs are getting smaller for the same price, which means they are getting more expensive for the same size. At some point, the price per transistor will actually increase. Then Moore's Law (the exponential increase in transistor density) will probably stop, simply because it's not economical to produce slower chips for the same price. (Maybe the increased power efficiency will still make density scaling worth it for a little while longer, but probably not a lot longer.)
They are simply making greater % profit/transitor.
Because neither AMD nor Intel can come withing striking distance of Nvidia's flagships, and seeing how their silicone flies off the shelves, they have also adjusted their pricing to match their relative performance to Nvidia.
The top GPU is the 3060, at 4.89% which both Intel and AMD match with their offerings [1]
The top AMD dGPU is still the RX 580 at 0.97%
