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 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 processor power, this suggests that the A15 shows less improvement over the A14 than it does over the Qualcomm processors in leading Android phones. And it makes me wonder if Apple is perhaps trying to soft-pedal a new chip that isn’t much faster than the older model […]
Over the past few years, each successive chip generation has offered a roughly 20 percent 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 about how big a step forward the A15 processor will really be.
SemiAnalysis believes that the next generation core was delayed out of 2021 into 2022 due to CPU engineer resource problems. In 2019, Nuvia was founded and later acquired by Qualcomm for $1.4B. Apple’s Chief CPU Architect, Gerard Williams, as well as over a 100 other Apple engineers left to join this firm. More recently, SemiAnalysis broke the news about Rivos Inc, a new high performance RISC V startup which includes many senior Apple engineers. The brain drain continues and impacts will be more apparent as time moves on. As Apple once drained resources out of Intel and others through the industry, the reverse seems to be happening now.
We believe Apple had to delay the next generation CPU core due to all the personnel turnover Apple has been experiencing. Instead of a new CPU core, they are using a modified version of last year’s core.
