苹果将A8处理器称之为次世代处理器(直接翻译"下一代处理器"？)，64-bit架构，armv8指令集不用多说。相比于A7 chip速度提升25%，芯片尺寸减小13%(对iphone6纤薄的机身设计有帮助)，显然，A8 chip在节能方面提升了50%。
苹果宣称，搭载A8 chip的iphone的续航时间如下
3G 通话: 14 hours for iPhone6, 24 hours for iPhone6 Plus
待机时间: 10 days for iPhone6, 16 days for iPhone6 Plus
视频播放时间: 11 hours for iPhone6, 14 hours for iPhone6 Plus
A8 chip 增强了图形(GPU)性能，支持画质更好的游戏，各大游戏大厂将持续为苹果设备带来新的大作。
M8协处理器增加了海拔气压计。
Apple*s calling a "next-generation" A8 chip. But what can it do for you? Apple*s saying it brings a 25 percent speed boost over the iPhone 5s* A7 chip, with a 13 percent size decrease (assuredly helping to keep the duo of iPhone 6 phones so svelte). As much as we like performance, we also like our phones to last longer than five hours -- what does the A8 offer in energy conservation? A 50 percent increase over last year, apparently.
What that actually means in terms of real-life performance is another question -- we*ll have to find out when we get our hands on review units in the coming weeks. For now, Apple*s offered the following stats: 14 hours of 3G talk time for the 6, and 24 for the Plus; 10 days standby for the 6, 16 for the Plus. It also touts 11 hours of video for the 6, and 14 for the Plus. That*s straight from our liveblog as Apple announces new products today in Cupertino, California.
Apple*s also boasting of the A8*s graphics prowess, enabling better-looking gaming in particular. Epic Games, EA and a variety of others are apparently (still) on board to create games for Apple*s devices.
In addition to the A8 inside the new iPhones, an M8 coprocessor handles the usual gamut of sensory readings, and adds a new one: a barometer for elevation. We expect to hear much more about the M8 as Apple speaks to HealthKit and its new Apple Watch wearable. |
