iphone之前是a14仿生产品

The ‘time flies’ event that streamed today brought some major upgrades to Apple Watch & iPad line up, and disappointed fans who were expecting a new iPhone. But one of the most prominent announcements of the day was the latest A-Series processor. Usually, Apple announces the latest chips during the iPhone launch event. In the past years, the launch of a new chip in the A-series has been one of the key highlights of every iPhone launch event where Apple talks about how great the chip is going to be in terms of performance inside the iPhone. Apple has been continuously pushing the limits every year in terms of CPU and GPU with these bionic chips and this year is no different.

今天举行的“时光飞逝”活动带来了Apple Watch和iPad系列的一些重大升级，并让期待新iPhone的粉丝失望。 但是，今天最突出的公告之一是最新的A系列处理器。 通常，苹果会在iPhone发布会期间宣布最新的芯片。 在过去的几年中，A系列新芯片的发布一直是每次iPhone发布活动的主要亮点之一，在每次发布活动中，苹果公司都谈到了该芯片在iPhone内部的性能方面将有多么出色。 苹果公司一直在不断使用这些仿生芯片来推动CPU和GPU的极限，今年也是如此。

In today’s event, Tim Millet — VP, Platform Architecture at apple unveiled the latest A14 Bionic Chip which Apple claims to be the first chip in the world that uses the five-nanometer process technology. That is a long way from the A4 chip that was originally featured in the first-generation iPad from 2010. In case it’s not clear yet, the dimensions of the 5nm transistors are measured in atoms.

在今天的活动中，苹果平台架构副总裁Tim Millet推出了最新的A14仿生芯片，苹果声称这是世界上第一个使用五纳米Craft.io技术的芯片。 距离2010年第一代iPad最初采用的A4芯片还有很长的路要走。如果还不清楚，5nm晶体管的尺寸以原子为单位。

The A14 contains a whopping 11.8 billion transistors inside it, a 40% increase compared to the A13’s 8.5 billion transistors. A14 also got a pretty good update in terms of CPU, featuring a 6-core design including 4 high-efficiency and 2 high-performance cores that can give a 40% boost in CPU performance compared to its predecessor. The GPU has also got a major upgrade from the older chip, with the new 4-core graphics architecture Apple promised to deliver a 30% improvement in graphics.

A14内部包含多达118亿个晶体管，比A13的85亿个晶体管增加了40％。 A14在CPU方面也进行了相当不错的更新，采用6核设计，其中包括4个高效和2个高性能内核，与之前的产品相比，可以将CPU性能提高40％。 GPU还从旧芯片进行了重大升级，Apple承诺采用新的4核图形架构，将图形性能提高30％。

Apple has already set the standards high for machine learning capabilities on mobile chips with last year’s A13 and this time they have doubled the number of cores to build a 16-core architecture for Neural Engine. Apple claims that it is capable of performing up to 11 trillion operations per second, allowing machine learning and AI apps to harness power unlike anything before, on a mobile device. The CPU also contains a second-generation machine learning accelerators with accelerated matrix multiplication that can perform machine learning calculations 10 times faster compared to the older chip.

苹果已经在去年的A13上为移动芯片上的机器学习功能设定了很高的标准，这次他们将内核数量增加了一倍，从而为神经引擎构建了16核架构。 苹果声称其每秒能够执行多达11万亿次操作，从而使机器学习和AI应用程序能够利用移动设备上前所未有的力量。 该CPU还包含具有加速矩阵乘法功能的第二代机器学习加速器，与旧款芯片相比，其执行机器学习计算的速度快10倍。

The chip also features the latest image signal processor for higher quality photos and videos and a faster secure enclave for Touch id ( for the new iPad). All these features along with the numerous custom technologies that can drive the unique iPad experience will attract gamers and professionals with the best performing mobile chip ever. Whereas app developers can take full advantage of the chip features to build more powerful and high performing apps that could only run on a Mac or PC before.

该芯片还采用了最新的图像信号处理器，可以处理更高质量的照片和视频，并为Touch ID(适用于新iPad)提供了更快的安全区域。 所有这些功能以及可带来独特iPad体验的众多定制技术，将吸引游戏玩家和专业人士使用性能最佳的移动芯片。 应用程序开发人员可以充分利用芯片功能来构建功能更强大，性能更高的应用程序，这些应用程序以前只能在Mac或PC上运行。

Interestingly Apple also announced that iOS 14 will be made available to the public tomorrow, which is again very unusual for Apple to release the latest mobile OS before the new iPhone. This along with the announcement of the A14 chip has left many people wondering if there’s something up in their sleeves left to be the highlight of the upcoming iPhone launch event that may happen very soon in October. As always Apple likes to keep us guessing till launch day.

有趣的是，苹果还宣布将于明天向公众开放iOS 14，这对于苹果在新iPhone之前发布最新的移动操作系统再次是非常不寻常的。 伴随着A14芯片的发布，许多人都在想，是否还有剩余的东西成为即将在10月即将举行的iPhone发布会的亮点。 一如既往，苹果喜欢让我们一直猜到发行日。
