This is simply a matter of adding more cores...I mean, I would hope the 5950x with its 16 full strength cores would be better than an M1 with it's big/little design...
Looking at the die shot [1], they have plenty of space for cores and cache if they remove the GPU. Surely it's not that simple, but I believe they should be able scale to at least 8+4 cores without large interconnect changes, and at that point they are already knocking on the 5900X's door.
