At this point, we're pretty sure we know what the iPhone models will look like this year. We expect a 6.5-inch OLED model, a 5.8-inch follow-up to the iPhone X and a 6.1-inch LCD model with the same edge-to-edge design as the iPhone X. What we do not know yet is what Apple will do in 2018 to improve the internals of its iPhone line, but on Monday Macworld put together a compelling set of predictions for the new models.
Before we go further, it is worth noting that they are predictions based on trends from previous years and what we know about technological advances, not leaks or the like. There's only so much progress that Apple can make while keeping costs down, so if it's really an "S year," those predictions are probably prudent.
Most likely, Apple will launch the A1
In other words, if Apple produced the exact same A11 Bionic chip with the 7nm process could be 40 percent smaller and either consume 40 percent less power at the same speed or run at the same time with 20 percent higher clock speed Power. You can be sure that these are the best case numbers.
As Macworlds Jason Cross then finds, Apple will not release the same chip with a new process. It will build a more advanced chip that surpasses 2017's chip. The question is now, how far Apple can increase its performance with its new chip. Fortunately, in recent years it has not been difficult to spot a pattern.
If one supplies Apple sticks with the same six-core design (two high-power, four energy-efficient), the Geekbench 4 single-core score should pick up again a linear fashion, probably from the 4217 of the A11 about 5000 goes up. This should increase performance by up to 20%. As far as the multi-core score is concerned, it should be noted that the A11 made a huge leap last year (almost three times the increase from 2015 to 2016). It is therefore unlikely that we will see the same improvement again. Cross explains why this will not be the case:
[…] The A11 has fundamentally changed the way multithreading works. A new second-generation performance controller was introduced that allowed all two large cores and the four small cores to work simultaneously for the first time. That had a big impact on the multi-core performance. The A12 could have faster cores and could even be more efficient at using them all at once, but it will not have the advantage of being able to use more of them at the same time than ever before.
We expect multi-core performance to improve by 25 to 30 percent, giving us a score of Geekbench 4 close to 13,000.
The article contains a multitude of interesting conclusions based on trend lines and data from previous years. The most relevant for casual observers is battery life. While transitioning to a 7nm process could potentially lead to better battery life, the increased power consumption of a more complex A12 chip is likely to negate this. However, the next iPhone models may have a longer battery life than older models. You will not be able to surf the internet any longer, but it could take longer for your phone to idle.
