LG's new Optimus 4X equipped with quad-core chips
Lead: PCWorld article Monday said the smartphone with quad-core processors can provide a PC-like performance, these phones already in the Barcelona Mobile World Congress (hereinafter referred to as "MWC"). However, analysts believe the price and inspiron e1705 battery life issues will be the main factors restricting the development of these phones.
The following is the text of the article:
Several new product launches
The speed of the quad-core processors faster than the mainstream dual-core processor, dual-core processor phone has a lot of the market. However, the higher the cost of the quad-core processors, which will push up the retail price of smart phones. In addition, support for multi-tasking and high-performance applications, the power consumption of these processors is huge.
In the MWC this year, several companies introduced a smartphone with quad-core processor and Android 4.0 system. These phones include the use of the Nvidia Tegra 3 processor HTC One of the Optimus, LG 4X HD and ZTE Era, as well as independent research and development processor Huawei of Ascend D. These mobile phones are expected to be available later this year.
Analysts pointed out, performance, smart phones also need to remain competitive in the power consumption and price. In the dual-core mobile phone instead of the mononuclear cell phone, quad-core mobile phone is likely to target the high end market.
Price and power consumption constraints
In-Stat's chief technical strategist Jim McGregor said Jim McGregor, relative to the dual-core processor, quad-core processors are more expensive, this will be reflected in the price of smart phones. If consumers pay more attention to mobile performance, you might buy a quad-core mobile phone, and in some cases as a PC to use.
McGregor said that, as operators subsidized shipments of smart phones is growing rapidly, the market has been flooded with dual-core mobile phone. In the price of the smart phone is not subsidized in developing countries, the quad-core mobile phone can be very expensive, which is not conducive to the universal.
In addition, the quad-core processors can be very power. Due to the support of 4G networks and high-resolution display, the power consumption of the smart phone has been great. Run complex applications will accelerate in the quad-core processors based on power consumption.
Necessity of being questioned
J. Gold Associates analyst Jack Gold said Jack Gold, the ultimate multi-core processors in the smart phone will be very important, but whether this processor should depend on mobile phone design. The phone should be designed to seek the best balance between performance, battery for COMPAQ HSTNN-DB02 life and user experience.
Gold said: "If you are a high-end mobile phone gamers, running applications and operating systems know how to use multicore processors in a suitable manner, then there is no doubt that you will benefit." However, most smart phone applications are lightweight, simply use less memory, quad-core processors do not need to bring the powerful computing power.
Gold said: "most of the applications has yet to take full advantage of multi-threading capability of multi-processor core, especially considering the use of multiple display core to the phone, which also provides the ability of parallel computing."
Some processor vendors are committed to minimize power consumption, thereby extending Dell inspiron 1545 battery life. Nvidia said Tegra 3 quad-core processors can provide excellent Dell latitude d820 battery life, smart phones, while improving the computational performance. The processor will automatically shut down the inactive core, and another low-power core to run tasks such as messaging and music playback, thereby reducing power consumption.
Integrated in the Tegra 3 4 ARM Cortex-A9 core, had been used in the ASUS Eee Pad Transformer Prime Tablet PC. Tablet toshiba satellite a105-s4364 battery life has been remarkable. Compared to smart phones, tablet PCs will be more to run high performance applications, which can make better use of the quad-core processors.
Intel's point of view
Processor core in the smartphone war is similar to the multi-core processor of the PC market a few years ago World War II. Intel and AMD for laptops, desktops and servers introduced a variety of multi-core processors to improve performance and reduce power consumption. However, the notebook mostly still using the dual-core processors.
In the MWC this year, Intel CEO Paul Otellini (Paul Otellini,) said that the number of smart phones, more importantly, not the processor core, but the system-level performance. Intel is moving into the mobile processor market. Otellini said: "I think the comparison of the number of cores is not appropriate, it is important to your overall performance, and this performance along with energy consumption."
Nvidia rival, Texas Instruments has yet to launch quad-core processors. The company said, will focus on the dual-core mobile processor power consumption and price considerations.
Insight 64 principal analyst Nathan Brookwood (Nathan Brookwood), said that once the user to see a faster quad-core mobile phone, it will be not easy to re-use dual-core mobile phone. He pointed out that the Nvidia processor vendors and mobile phone design company is introducing a quad-core processors. In addition, the Android 4.0 system can make better use of the quad-core processors, the operating system upgrade in the future will be more and more to consider this issue.
