Estimated SPECint scores for designs that are not yet finalized on nodes that are not yet shipping. By the time these appear in laptops they'll be against Intel's Whiskey Lake running at 31% higher clock speeds than the 7300U. The 8565U, a 14nm design, will be as fast as ARM's predicted 2020 5nm in single-thread performance. Sure, it'll use twice the energy but that's the price for being a few years earlier and two nodes behind.
For Windows, the emulation simply isn't fast enough and is awful for battery life. Apple and Google may end up with ARM-based laptops, since Google does web technology and Apple doesn't worry too much about backward compatibility. But Windows is stuck with x86 and its derivatives.
