Here's a video explaining the relationship between resolution and CPU use - the conclusion - the CPU usage stays the same regardless of 720/1080/4K - so the premise of your statement is flawed - there's no reason to downgrade the CPU in Lockhart just because it is outputting at a lower resolution... If the 2 skus were targeting different frame rates, then yes, you'd have a point, but resolution, no...

Not always though.
For example... What happened very often during the 7th gen and on the rare occasion in the 8th gen... The CPU was tasked with performing a post-processing filter to clean up the image. I.E. Morphological Anti-Aliasing.
The higher the resolution, the more work the CPU needs to do.
When it comes to draw calls... Often that is the job of the CPU, the higher performing console will likely have things like longer draw distances and so on, so that is an increase for that too.
The Xbox One X manages to offload some of that to the command processor on the GPU side of the equation... So it will actually be interesting if Microsoft continues down that same path for next-gen.

If they use the same CPU across both, different GPUs as leaked, a bit less RAM for Lockhart due to smaller 1080 textures and potentially even a smaller hard drive for Lockhart (though that is contrary to leak)

Hopefully they don't use 1080P textures... (Yes I know what you meant, but even 7th gen games used textures larger than that. :P)

Yeah, now your going way over my head :)
What do you think of the overall proposition though, could MS feasibly produce a 1080 & 4K sku that wouldn't step on each other's toes in regards to development and significantly hamper dev's in making the most of the higher sku? If they were to make that one of the priorities in their planning?
You can probably save us a few dozen more pages of non-experts (I'm obviously including myself here) going back and forward!
