While I agree that this time Apple is close to QC there are two things that everyone seems to gloss over.

1) What is the energy used per bit to do the above? How much of that is antenna design as you point out? When I measured the difference between Intel and QC modems (iPhone 6/7 gens), both showed an ~30% difference in energy used (Note: Not per bit, that adds another ~30% for Intel on these devices). This is across multiple gen of modems and the QC devices were in the same (less efficient for them) modes as Intel.

2) The QC modem was either 1.2x or 2x as fast as the Intel part depending on which QC device you compare it to, 845 or 855. This is not a minor difference in capabilities or efficiency.

So what you are saying is that in 'year old+' modes, Intel can finally match QC in one aspect of the game. Yay? Intel promised Apple a Gb modem for the iPhone 7. And 8. And I have them on record as saying that the Xx class of devices was supposed to be 1.2Gbps. Ooops.

I would be much happier patting Intel on the back for this signal quality if I didn't know what they were _SUPPOSED_ to have delivered. That said it is still a BIG step up for them.
