ATI揭秘你的功耗 人脑是HD4870的400倍

  在AMD的官方演示文稿里,我们发现了一个有趣的对比,就是让人类的大脑和AMD RV770图形芯片来一次性能上的PK:) m1 T4 u. w) A4 F7 q

  AMD称,RV770的计算能力和存储带宽分别为1TeraOps(每秒一万亿次操作)和1Tb/s,而人脑可达100TeraOps和10Eb/s,是其100倍和10000倍。( o9 A8 D- ?. E5 l, b

  消耗的能量方面,RV770显卡需要最多150W,而人脑不过30W,这样对比下来,双方的性能功耗比分别为0.007TeraOps/W和3TeraOps/W,人脑是RV770的400多倍。人类大脑的高性能和高效率由此可见一斑。. ~- O7 E: \- n+ {

  另附来自AMD的R700 Radeon HD 4870 X2与GT200 GeForce GTX 280对比视频。看起来是在R700发布之前制作的,在3DMark Vantage、《使命召唤4:现代战争》、《失落星球:极限状态》三个方面进行了PK,,结果自然是R700大胜。

ATI都几无聊窝

原來人腦可以这么厲害

大脑会消耗掉人体大部分的养分!所以大脑的功耗还是很高的

At present, the mainstream of the smartphone operating systems including Symbian, Windows Mobile and Linux, and so on, each has developed into a more mature mobile application platform. One, Symbian currently holds the largest market share, Windows Mobile has the best PC compatibility, Linux is reflected in the development of more flexible and customizable nature. In addition, a number of professional application platforms, such as RIM's Black Berry, Apple's iPhone, such as Mac OS operating system, is also a new attitude emerging. These were smart phone operating system and its corresponding end to the perfect combination for the consumers to experience high-quality operation at the same time, for a variety of software applications to provide a wealth of strong support for the environment.

Compare the current 2.5G applications, the Chinese mobile phone software business mainly based on the K-Java treasure chest of business to start operations. However, K-Java platform to the extreme lack of control over the hardware device, which allows terminal manufacturers to introduce a variety of cameras, memory cards, Bluetooth devices, such as in the K-Java platform are difficult to display their abilities. The smart phone operating systems can operating in depth the underlying hardware, such as software developers will be able to join the Symbian platform on the development of camera-enabled mobile phones to identify the game, and so on, this is the current K-Java platform can not be done.

  In addition, a variety of smart phones, without exception, are equipped with PC and data communications lines and even individual cell phone began to have a wireless connection of Wi-Fi functionality. In this way, the last of the traditional mobile remote central office to download the application of a single release channel are gradually being broken, more and more users do not need the involvement of mobile operators will be able to download and install from the other channels to use their own favorite applications. For example, is the author used a Windows Mobile phone, not only with USB / IR / Bluetooth connection with the computer automatically synchronize Outlook information, a variety of software installation procedure is as easy as using USB.

  For such as Nokia and Motorola mobile phone terminal operators, handset in the face of homogenization and increasingly fierce price war, which is badly in need of new business growth point to maintain the leading position in the market. Nokia, for example, it has in the past, "mobile phone"
Completely changed the positioning of the brand-new "multimedia computers" and the network, software, Web2.0 and so force in an attempt to create an integrated platform for the great wireless applications. This includes Microsoft's operating system providers, but also through mobile phone operating system software with its PC business integration, to implement the gradual penetration of the market. Apple shocked early in 2007 released a new iPhone mobile phone concept, in addition to its stunning appearance, the integration of Google, Yahoo and other Internet applications, is also one of its biggest selling point. These companies have their own rich market experience and strong R & D resources to the accumulation of design, and their full involvement in the field of telecommunications has made it more and more IT and the Internet zone with multiple features.

Today, the smart phone's share of Chinese mobile phone market has been close to 10% over the next five years and will maintain double-digit growth rate. The Chinese market is due to the promotion of concepts such as 3G, will soon be ushered in the smart phone market, the outbreak of the period. I expected to see five years, with the central office end of the separation of the dual platform application framework for 3G mobile phones will in fact be established. In that case, operators should be how to deal with these new technologies and the impact of this application?
