Moving to a new process node gives you a choice of increasing performance or lowering power draw. Apple has been unusual in that they have not pursued "performance no matter what it does to power draw and heat" like other companies have in recent years. > On the CPU side of things, Apple’s initial vague presentation of the new A15 improvements could either have resulted in disappointment, or simply a more hidden shift towards power efficiency rather than pure performance. In our extensive testing, we’re elated to see that it was actually mostly an efficiency focus this year, with the new performance cores showcasing adequate performance improvements, while at the same time reducing power consumption, as well as significantly improving energy efficiency. https://www.anandtech.com/show/16983/the-apple-a15-soc-performance-review-faster-more-efficient/4 https://www.anandtech.com/show/16983/the-apple-a15-soc-perfo... Others may make different choices. The early reporting said the A17 improved the performance on the big cores by 10%, but not the little cores. If they had used the node change oooortunity for performance increases, you would expect to see the gains on both the big and little cores. > Apple says the performance cores are 10 percent faster than they were before, a relatively mild improvement, while the efficiency cores are more efficient rather than being faster. https://arstechnica.com/gadgets/2023/09/apples-new-iphone-15-pro-gets-new-chips-better-cameras-and-a-titanium-frame/ https://arstechnica.com/gadgets/2023/09/apples-new-iphone-15...
