元器件交易网讯 3月10日消息，据外媒报道，芯片制造商英特尔推出了最新的22nm双核和四核64位Atom系统芯片，并声称比苹果A7和高通Snapdragon 800 CPU的速度更快。
在2014年移动通信世界大会（MWC）上英特尔面向智能手机和平板电脑推出了两款基于22纳米的64位Atom处理器，分别是Merrifield Atom Z3400和Morrefield Atom Z3500。
22纳米双核Z3400和强大的四核Z3500芯片都是基于英特尔全新的Silvermont芯片微架构，相比于前几代产品，有了许多改进，从32纳米缩小到22纳米，主频升级（Z3480运行2.13GHz，上一代Z2580运行2GHz），并有显卡升级，特别是2D性能。
据英特尔全球首席基准测试经理马特·邓福德（Matt Dunford）表示，这些改进使得Atom芯片的整体性能高于苹果iPhone 5S的A7芯片，及高通Snapdragon 800芯片。
邓福德还声称，新Atom芯片的电池续航时间比苹果或高通CPU更好。
这款芯片同时拥有大量类似于苹果M7协处理器的低功耗传感器。这些传感器可向主机提供运动感应、位置、手势感应甚至音频感应等类似信息。这样，应用程序可以在不大量消耗电量的情况下利用这些信息。
英特尔预计手机制造商将于第二季度开始推广搭载该CPU的设备。（元器件交易网郭路平 译）

Intel claims new 22nm Atom 64-bit mobile chips are faster than Apple"s A7 CPU
Summary: Chipmaker Intel unveils new 22nm dual-core and quad-core 64-bit Atom SoCs which the company claims is faster than Apple"s A7 and Qualcomm"s Snapdragon 800 chips. Chipmaker Intel has used Mobile World Congress currently in progress in Spain to unveil two 64-bit enabled system-on-a-chip (SoC) updates across its Atom range of mobile processors. The 22nm dual-core Z34XX part, along with the beefier quad-core Z35XX chips, previously codenamed Merrifield and Moorefield respectively, are based on Intel"s new Silvermont chip microarchitecture, and bring with them a number of improvements compared to the previous generations in the form of a die shrink from 32-nanometers to 22-nanometers, clock speed upgrade (the Z3480 runs at 2.13GHz compared to 2GHz for the previous-generation Z2580), and graphics upgrade, in particular 2D performance.
According to Matt Dunford, worldwide Chief Benchmarking Manager at Intel, these improvements bring the overall performance of the new Atom chips above that of Apple"s A7 chip which is found in the iPhone 5S, and Qualcomm"s Snapdragon 800 part.Dunford also claims that battery life for the new Atom chips is better than for the Apple or Qualcomm parts.
The new chips also feature a raft of low power sensors similar in nature to Apple"s M7 coprocessor. These sensors provide the device with information such as motion sensing, position, gesture sensing, and even audio sensing, so apps can make use of this information without knocking battery life too hard.
Intel said it expects devices from "multiple" handset makers to launch beginning in the second quarter.
