Performance comparisons between iPhone 13 and iPhone 12 are missing

An interesting thing was missing in yesterday’s keynote: Despite all the time Apple spent talking about the chips, there was no comparison between the iPhone 13 and the iPhone 12.

Usually Apple tells us how much faster and more powerful the latest iPhone is compared to the previous model, but this time it did not – which led some to conclude that there is a good reason for this …

Apple told us how much the iPhone 13 battery life has improved on the iPhone 12. It told us how much better the cameras are. It told us about the smaller notch, new stock levels, new colors, ProMotion display, new cases and more. But the only performance comparisons were with unspecified Android phones.

Macworld ‘s Jason Snell notes that this is unlikely to be an unintentional omission.

Here’s a funny thing about Tuesday’s announcement of the A15 Bionic: Apple did not compare its performance with the A14. In the past, Apple has compared the power of its iPhones with previous models. But this year, Apple has chosen to proclaim that the A15 in the iPhone 13 Pro has 50 percent better graphics and CPU performance “than the competition.”

Given that Apple has generally been ahead of its smartphone competition in terms of processing power, this suggests that the A15 shows less improvement over the A14 than it does compared to Qualcomm processors in leading Android phones. And it makes me wonder if Apple might be trying to soft-pedal a new chip that is not much faster than the older model […]

Over the last few years, each successive chip generation has offered an improvement of about 20 percent in single-core performance. This year may be different. While the introduction of a new A-Series processor is always a big deal, it’s an open question about how big a step forward the A15 processor really will be.

Semi-analysis expresses it even more directly, claiming that Apple has lost its best chip engineers and as a result is unable to offer the performance improvements it has previously had.

Apple’s CPU stops and the future looks bleak as the impact of the CPU engineer’s emigration to Nuvia and Rivos begins to soften […]

Apple has long been hailed for having the best CPU cores for consumer workload for years. They have by far the highest performance per. Clock and efficiency driven by performance in the same class as AMD and Intel’s best current CPUs. This was driven by tremendous gains with architectural changes every year for a decade.

Now with the A15, those gains are really slowed down. Apple was generally very clumsy with the A15 comparison in the new iPhone unveiling. Instead of comparing it to the previous generation as they usually do, they chose to compare with ambiguous “competitors”. It’s great, but we’re just a few months away from new Qualcomm, Samsung, and MediaTek chipsets.

The site then presents evidence that the A14 and A15 performance are likely to be almost all identical, based on Apple’s performance requirements for the new iPad mini.

The most important thing to note is that the CPU gains are identical from A12 to A14 as they are from A12 to A15.

It says the likely explanation is brain drain.

SemiAnalysis believes that the next generation kernel was delayed out from 2021 to 2022 due to CPU engineering resource issues. In 2019, Nuvia was founded and later acquired by Qualcomm for $ 1.4B. Apple’s Chief CPU architect, Gerard Williams, as well as over 100 other Apple engineers left to join this company. Recently, SemiAnalysis announced the news of Rivos Inc, a new high-performance RISC V startup that includes many leading Apple engineers. Brain drainage continues and impacts will be more apparent as time goes on. Since Apple once drained resources out of Intel and others through the industry, it seems that the opposite is happening now.

We believe that Apple had to delay the next generation of CPU core due to all the staff turnover that Apple has experienced. Instead of a new CPU core, they use a modified version of last year’s core.

The bottom line seems to be: Do not buy iPhone 13, which expects a lot in terms of performance improvements.
