I mean, they also were able to cheaply increase core count by not stuffing an iGPU into the chip. Outside of HEDT CPU's on the Intel side you have no choice on whether you get HD/Iris/Iris Pro graphics, even if you're going to put a gaming GPU in the system anyway. Meanwhile, the mainstream AM4 platform is based around the assumption you'll be sticking a GPU in already so space on the CPU die is better used for more cores.
