Eh, I have a sneaking suspicion the compute dies won't be shut down as much as you'd think, and that there will be some extra power usage from crossing the dies like desktop Ryzen parts (though hopefully not nearly as severe).

A good Process Lasso config is probably worth the time investment. Instead of "trusting" the scheduler, you could force everything non time sensitive onto the efficiency island, maybe by default.

The 3D Foveros packaging technology is critical as it allows some path lengths to be much shorter than if you had to traverse that same path but only in the horizontal 2D plane.

Very excited to see how this plays out in practice.

I thought Meteor Lake was tiled and 2D? Intel has EMIB and such for very good bridges, but they are still bridges.

If it is 3D stacked with TSVs, thats a whole other can of worms. AMD's X3D on Ryzen 7000 creates heat/clockspeed issues, and they reportedly canceled a 3D variant of the 7900 GPUs due to similar issues.
