Today, Macworld conducted an analysis of the improvements to the iPhone's flagship model this year. Part of the analysis is based on the 7nm process used by TSMC's claimed A12 chip, and some based on previous performance improvements. The report points out that Apple insists on working with TSMC. To produce A12, we can first look at how good TSMC's new process is. TSMC says that the 7nm process provides '1.6x logic density, 20% speed increase, 40% compared to the 10nm process used in A11 biochips. Reduced power consumption'.
In other words, if Apple's A11 biochip uses a 7nm process, it can be as small as 40%, and the power required to achieve the same speed can be 40% less, and the same power consumption can achieve 20% faster. However, Macworld said, A fact that is easily overlooked is that the A12 is a more complex chip and is unlikely to have a big boost to speed. Given the dramatic jump in A11 performance, this year is unlikely to repeat itself.
A11 has made major architectural changes to how multithreaded performance works. It introduces a new second-generation performance controller that allows two large cores and four small cores to work simultaneously for the first time. This has a huge impact on multicore performance. A12 may have a faster kernel, and may even use them more efficiently, but it won't have the advantage of being able to use more cores at the same time.
Therefore, Macworld expects A12 multi-core performance to increase by 25% to 30%, and its Geekbench 4 running score may be around 13000. GPU performance may increase even higher (in the 40% range), but it is unlikely to be directly converted into games. Performance. Macworld predicts that although Apple will quote higher numbers, the actual performance improvement may be around 15%-25%. Although the theoretical improvement of the 7nm process may be offset by the greater demand of the A12 chip, there is a good The news is that Macworld believes that the iPhone's standby time this year will be longer than the existing iPhone X.
