graph shows reduction in chip performance gain – Gadgets – Tecnoblog

Who thinks the iPhone 13 there is not much difference compared to last year’s model, at least a little bit of reason. At least that’s what a graphic made by Creative Strategies consultancy shows. Apple’s flagship has seen increasingly smaller performance increases compared to its predecessor.

The Geekbench 5 Single Core CPU Score is a score that measures the performance of a single processor core. This benchmark was used by Creative Strategies as a reference. In a graph, it shows the results for each iPhone (the bars in orange) and the difference from its predecessor (the dots and lines in red).

The bars are always bigger than the old ones — after all, the new one is always faster than the old one. The problem is the how much it is faster: this difference has become smaller and smaller, as can be seen in the downward trajectory of the orange line.

Looking at longer periods, you can see how this has changed. From the 2014 iPhone 6 A8 chip to the 2017 iPhone 8/X A11 chip, the performance score grew by 192%. From the A12 of the Xs (2018) to the A15 of the 13 (2021), the increase was 91%.

Slower pace matters for those who change iPhone every year

From the standpoint of industry and the specialized media, the slower pace of improvement draws attention, but maybe that doesn’t matter. so much for the consumer.

The difference in perception has a reason: the vast majority don’t buy a new iPhone every year. Obviously, there are people who change their device every year or every two years, but those are the minority. Creative Strategies says the most common purchase cycle is between three and four years.

With that, anyone who owned an iPhone XS and moved to the 13 after three years will receive almost double the performance of single core. Since the iPhone 5s, the performance jump every four years has averaged 133%.

5 nm process of A15 is the same as A14

One of the reasons for the small evolution of the A14 to the A15 is the same 5 nm lithography process. This means that there hasn’t been an evolution in the size of transistors, and that makes it more difficult to put more in the same physical space.

Without this miniaturization, it is difficult to increase performance. The expectation is that the A16 of the iPhone 14 will overcome this barrier.

iPhone 13 Pro GPU had significant increase

If the iPhone 13’s single-core CPU performance isn’t much higher than that of the iPhone 12, the same cannot be said of the difference between the graphics processing units, the GPUs.

How does the Macworld, the A15 is almost a product line, as it is used in different ways in each device. The iPad Mini, for example, has a lower clock speed than iPhones. The iPhone 13 has four GPU cores, against five of the Pro model and tablet.

Because of these differences, in the site’s tests, the iPhone 13 Pro’s GPU scored 51% higher than the 12 Pro’s: 14,140 against 9,322. The regular model scored 10,863, an increase of 16% over the 12 Pro.

Other features get more attention

Creative Strategies also argues that the single-core performance comparison does not reflect the device as a whole. As analyst Ben Bajarin recalls, the chip is not Apple’s product, but a part of the iPhone — an important part, it’s true, but nothing more.

So even with a small performance improvement per core, the company is able to tweak the entire suite and deliver better features like longer battery life or new advanced photo and video capture tools.
