What interface do our GPU's use? The PCI-e slot. I think that we all get turned off by the notion of slot based CPUs because we instantly think of the large and clunky Slot A and Slot 1 based processors from AMD and Intel way back when. Doesn't mean they cannot be utilised effectively today.
However, I don't think we'll be going bacl to slot-based CPUs for quite some time. Likely, for the duration of the ATX-form factor's life we'll be socket based. Only once ATX is replaced will we likely see something different.
You're missing a big issue here. Pcie bandwidth is NOTHING compared to what a CPU needs. Pcie 2.0, 8GB/s, and 3.0 still only 16GB/s. While the cpu to memory bandwidth is 64GB/s. You would be severely bandwidth starved with slot cpus.
