Yes, decent iGPU. But no on an external GPU in the back since this is for the 13" which has no modular bay for internal GPU (They mean a USB4 -> PCIe dock for the external GPU).
There IS a 16" coming that will let you plugin a dedicated GPU.
I will probably order this (or it's next version) one for my machine in 18 - 30 months since mine is only ~6 months old.
edit: and apologies if I mis-understood or am being pedantic
