Register files. Instruction scheduler(s). ROB. Bypass networks. Load-store queues. Caches. Branch prediction arrays and logic. Those are among the hottest parts in an OoO chip and it isn't because they are efficient.

For your claim to be correct there have to be new revolutionary physics involved that can make O(n^2) structures scale like O(n). Because the other optimizations that are used can also be used in a processor that doesn't use OoO execution - only making them more efficient.

The Mill attempts to remove explicit register files, expose the bypass networks. That alone (if it works) will reduce power consumption for data delivery. There are no instruction schedulers, ROB or load-store queues of the type used in OoO processors. There are chances that the cache design will reduce power too, however the public details aren't enough to tell ATM. Branch prediction is claimed to be simplified as it uses exit prediction of larger blocks.

Now it is reasonable to be skeptical to the claims about the Mill (as history have shown that even enthusiastic and skilled designers with a lot of cash available can fail to make statically scheduled high-ILP designs work well in practice) but the reality is that standard processors aren't efficient. They are more efficient than designs not geared towards power consumption, sure, but the fundamental limits are still there.

Why? Standard OoO processors are actually not especially MLP friendly, they aren't designed to be.

Of course it is true. The majority of power is wasted on overheads that comes from all direction, doing a floating point operation is cheap power wise - feeding the FP unit isn't.

And you think that the overheads suddenly evaporate when running AVX2 code? Only the instruction fetch and scheduling overheads are reduced while data feed overheads are increased in addition to the consumption of the extra FP units.
