The chart below shows iPhone 5s GPU performance over time. Each bar shows the average 3DMark Sling Shot Extreme Graphics test score calculated from all results submitted during that month.
A higher score indicated better performance. The bars are coloured according to iOS version.As you can see, iPhone 5s GPU performance has remained consistent from iOS 9 to iOS 11 with only minor variations that fall well within normal levels.![](https://www.futuremark.com/hwc/tmp/iphone5s-sling-shot-extreme-gpu-performance.jpg)
The next chart below shows CPU performance over time as measured by the 3DMark Sling Shot Extreme Physics test. Again, it is clear that iOS updates have not had a significant effect on performance.

The charts for the iPhone 6, iPhone 6s, and iPhone 7 tell a similar story. GPU performance has remained consistent across iOS versions with only minor variations.
The graphs for CPU performance show a very slight drop in performance over time - possibly due to minor iOS updates or other factors - but a user would be unlikely to notice this small difference in everyday use.
