Foreign media: A12 may be the beginning of Apple's self-developed computer chip.

Still ahead of the competition

A12 bionic chip is the first 7 nanometer process chip on consumer products.HUAWEIThe Kirin 980 was released, but the latter has not yet been installed on the machine, so there is some controversy about who was the first 7-nanometer chip.

According to AnandTech, the A12 chip has made significant improvements to the neural engine, with the redesigned system cache having "the biggest change since the introduction of A7," significant improvements to the CPU core, and memory compression on the GPU, all of which have brought impressive performance improvements.

At present, the energy consumption ratio of the mainstream chips is shown as A12 in dark grey, A11 in light grey, 9810 in Samsung, 845 in Mylon and so on.

Based on the SPECint2006 benchmark test, the average performance of A12 on the previous generation of equipment is 24% better than that of A11. Unit energy efficiency ratio (i.e. calculation versus power consumption) increased by 12%, but with the increase of cache, power consumption also increased, the average power consumption of A11 is about 3.36W, the average power consumption of A12 is 3.64W.

AnandTech benchmarks show that the A12's kernel and architecture improvements are actually "deeper than Apple's advertisements," outperforming Android's popular Exynos, Mylon and other chips in terms of performance and power.

AnandTech said the gap between the A12 and the previous A11 was "quite striking" and the desktop CPU, and they also showed how Apple could improve the performance of old devices through software tuning. withIPhone6S A9, for example, has a maximum CPU frequency of 435ms, but iOS 12's time is reduced to 80ms, "greatly improving the performance of interactive workloads."

A10 has made similar improvements (from 400ms to 210ms), but A11 has not changed much.

Overall, AnandTech says the iPhone XS and XS Max are a "big shift" in Apple's product line, with performance gains up to 40%.

To the desktopprocessorBasics?

But Apple's marketing department actually underestimates this improvement, only 15% - some foreign media estimate that the maximum workload performance will be around 40% - that's the limit, but it's rare for battery-powered handsets.

That reminds us of the rumor that Apple has been developing its own computer chips for years, and by A12, we might have seen some progress: Apple's own CPU performance has been so high that only desktop CPUs can take advantage of it.

So if Apple really uses this processor for computer devices in the future... That may make it possible for the two product lines with obvious boundaries to merge. In addition, Apple has always liked to control all the product segments by itself, before they dumped Qualcomm and later in the computer industry.IntelIt is not impossible.

We look forward to the future development.
