One interesting thing was missing from yesterday’s speech: Despite all the time Apple spent talking about chips, there was no comparison of how the iPhone 13 compared to 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 didn’t – leading some to conclude that there is a good reason for it. that…
Apple told us how much better the battery life of the iPhone 13 has improved compared to that of the iPhone 12. It told us how much better cameras are. He told us about the smaller notch, new storage levels, new colors, ProMotion display, new cases, and more. But the only performance comparisons were for unspecified Android phones.
Macworld ‘s Jason Snell notes that this is unlikely to be an accidental omission.
Here’s a funny thing about Tuesday’s announcement of the A15 Bionic: Apple didn’t compare its performance to the A14. In the past, Apple has compared the power of its iPhones to previous models. But this year, Apple chose to claim that the iPhone 13 Pro’s A15 has 50% better graphics and CPU performance “than the competition.”
Considering that Apple has generally been ahead of its competition in terms of processor power, this suggests that the A15 shows less improvement over the A14 than it compared to Qualcomm processors in major Android phones. And I’m wondering if maybe Apple is trying to use a new chip that isn’t much faster than the old model. […]
Over the past few years, each successive generation of chips has offered about a 20% improvement 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 how big the A15 processor has stepped forward.
Semi-analysis puts it even more bluntly, claiming that Apple has lost its best chip engineers and, as a result, is unable to deliver the performance improvements it had in the past.
Apple processor gains halt and the future looks bleak as the impact of the exodus of processor engineers to Nuvia and Rivos begins to be felt […]
Apple has long been praised for having the best processor cores for consumer workloads for years. They have by far the highest performance per clock and efficiency thanks to performance in the same class as the current best processors from AMD and Intel. This was driven by meteoric gains with architectural changes every year for a decade.
Now with the A15, these gains are really slowed down. Apple in general was very reluctant about the A15 comparison in the new iPhone reveal. Instead of comparing it to the previous generation as they usually do, they chose to compare it to ambiguous “competitors”. That’s great, but we’re only a few months away from the new Qualcomm, Samsung, and MediaTek chipsets.
The site then presents evidence that the performance of the A14 and A15 are likely to be nearly identical, based on Apple’s performance claims for the new iPad mini.
The most important thing to note is that the CPU gains are the same from A12 to A14 as they are from A12 to A15.
He says the likely explanation is the brain drain.
SemiAnalysis estimates that the next generation core has been delayed from 2021 to 2022 due to CPU engineer resource issues. In 2019, Nuvia was founded and then acquired by Qualcomm for $ 1.4 billion. Apple’s chief processor architect Gerard Williams, along with more than 100 other Apple engineers have left to join the company. More recently, SemiAnalysis announced the news from Rivos Inc, a new high-performance RISC V startup that includes many senior Apple engineers. The brain drain continues and the impacts will be more apparent as time goes on. As Apple once drained resources from Intel and others in the industry, the reverse seems to be happening now.
We think Apple must have delayed the next-gen processor core due to all the staff turnover Apple has experienced. Instead of a new processor core, they use a modified version of the core from last year.
The bottom line seems to be: don’t buy the iPhone 13 expecting a lot of performance improvements.
