Four processors faster than mainstream dual-core processor faster, at present the dual-core processor of cellular cellphone already large listed. However, the cost of four nuclear processor higher, it will push the retail price of smart phones. In addition, because of the task, and performance of the application more support, this kind of processor power consumption is huge.
In this year's MWC, many companies launched by four processors and Android 4.0 system of smartphones. These cell phones including the Nvidia Tegra 3 processor (micro Po) HTC One X, LG Optimus 4 X HD and zte's Era, and the independent research and development of the processor huawei Ascend D. Expect the handset will later this year with listed.
Analysts pointed out that, in addition to the performance, smart phones need in power consumption and prices remain competitive. Mobile phone replace mononuclear cell phone in dual-core after four nuclear mobile phone is likely to be aimed at high-end market.
Price and power consumption restriction
In-Stat chief technical strategist Jim mike Greg (Jim McGregor) said, compared with the dual-core processor, four processors is more expensive, it will be reflected In the price of smart phones. If consumers are paying more attention to mobile phone performance, it could buy four nuclear mobile phones, and in some cases as a PC to use it.
Mike Greg says, because operators provide subsidies, smartphone shipments is growing fast, the market has been filled with dual-core mobile phones. And in smart phones don't get subsidies of the developing countries, four nuclear price may be very expensive mobile phone, which is disadvantageous to popularity.
In addition, four processors can be very low power consumption. 4 G network and because of high resolution screen support, smart phones already large power consumption. On the basis of four processors running complex applications will speed up power consumption.
Necessity were questioned
J. Gold Associates chief analyst Jack Gold (Jack Gold) says, in the end, the multiple processors in smart cellphones will be very important, but whether to adopt such processor shall depend on phone design. Phone design should be in performance, battery life time and user experience between seek the best balance.
Al gore's said: "if you be a high-end mobile games to players and operation of the application and operating system know how to the right way, using multiple processors, so there is no doubt that you will benefit." However, most of the smartphone applications are lightweight, need to use less memory, so don't need four processors to bring strong ability of the calculation.
Al gore's points out: "most applications has yet to make full use of the core processor with multi-thread functions, especially when you consider that a cell phone still USES the more display the core, it also provides the ability of parallel calculating."
Some manufacturers are working to make the power consumption of the processor to minimize, thus extending battery life time. Nvidia says, Tegra 3 four processors in the smartphone can provide excellent battery life time, and improve computational performance. The processor can automatically shut off not core activities, and through another low power consumption to run the core text messages and music broadcasting task, so as to reduce power consumption.
Tegra 3 integrated 4 ARM Cortex-A9 core, having already used in the asus Eee Pad Transformer Prime tablet computer. This kind of flat computer battery life time to obtain the praise. But relatively in smart phones, tablet computer will run more high performance applications, it can better use of four processors.
Intel (the Po) a different perspective
The smart phone processor core wars is similar to the PC market a few years ago the hypercore processor war. Intel and AMD for laptop, desktop PC and server launched a number of multiple processors, in order to improve the performance and reduce power consumption. But now, most of them still using dual-core processor laptop.
In this year's MWC, Intel CEO Paul Otellini (Paul Otellini) said, in smart phones, the more important is not the number of core processor, but system level performance. Intel is foray into mobile processor market. Otellini said: "I think the core number of contrast is not appropriate, the important thing is you get the overall performance, and the performance of the energy consumption with."
As Nvidia competition, Texas instruments (the Po) has not yet been launched four processors. The company says, because the power consumption and price, consideration, will focus on dual-core mobile processors.
But Insight 64, chief analyst mulberry · brooke wood (Nathan Brookwood) says once users see the faster four nuclear cell phone, so will not too easy to use mobile phones to you. He points out that such as manufacturers and mobile phone Nvidia processor design company is introduced into four processors. In addition, Android 4.0 system can better use of four processors, the future of the operating system upgrade will also increasingly concerned with the problem
