News on November 19th, although quad-core mobile phones have begun to spread, but the core number does not completely represent high performance. Software developers say that most applications currently do not require quad-core, and simple multi-core will not have a significant performance improvement.
Multiple evaluation reports show that the upgrade of smartphones from single-core to dual-core quickly improves the performance of smartphones. During the process from dual-core to quad-core, the rendering speed of mobile applications has not accelerated.
In fact, in addition to Nvidia, MediaTek and other manufacturers accelerating the progress of multi-core, Qualcomm still uses dual-core S4 as the flagship product, while Intel, which has just entered the mobile phone chip market, still uses single-core chips to dominate the world.
Until 2011, with the Tegra 2 dual-core chip launched by Nvidia, the performance of the mobile phone was greatly improved, and the mobile phone entered the dual-core era. However, after the introduction of quad-core chips in 2012, the direction of nuclear war has changed.
Sun Changxu, chief analyst of "International Electronic Business", said that CPU performance is not equal to the number of cores. The structure of cores is different from that of cores. Consumers should not look at the price of cores, but should look at the performance of mobile phones in a comprehensive configuration.
Different options for chip manufacturers
The advocate of multi-core started from Nvidia. After Nidia just released the S2 dual-core processor, the company announced the quad-core Tegra 3 process map. After the official Tegra 3 release, the chip has an additional core for low-power applications. Now Nvida has thrown out the eight-core Tegra 4 route.
The same for multi-core is more with MediaTek. After the rapid follow-up of the quad-core, MediaTek quickly released the eight-core plan, but mobile phones based on the MediaTek quad-core processor have just entered the market.
Although Qualcomm launched the quad-core A7 Snapdragon processor, this behavior is more like a strategy to follow, because the quad-core A7 is listed by Qualcomm as an entry-level smartphone chip, while in the high-end field, Qualcomm still uses the dual-core S4 as the Lord. The dual-core processor used in the Nokia Lumia 920 has just been released. Qualcomm product management director SY Choudury once said that at present, there is absolutely no smartphone program that can exert the full performance of the quad-core processor.
HTC and Samsung all use quad-core chips in their flagship models, and Samsung Galaxy 3 uses its own quad-core chip. But at the same time, traditional manufacturers such as Motorola and Nokia have not released mobile phones based on quad-core processors. "Dual-core and quad-core mobile phones are just a waste of batteries, not all are so effective at all times." Nokia CEO Elop once said.
The latest processor analysis of iPhone 5 can also be seen, this is a dual-core chip, while iPhone 4 is a single-core processor product.
The experience depends on the application, not the core
It also supports the view of quad-core mobile phones. Xiangxiang, CEO of Flying Elephant, said that the ability to improve the CPU through multi-core is still a focus of smart phones to improve computing power.
However, in the eyes of developers, the reason why quad-core mobile phones have not significantly improved in performance is that there are no applications developed specifically. A developer said that currently there are few applications that can run the highest performance mobile phone chips at full capacity.
Hong Li, director of technology and product planning at Intel China Mobile Communications Division, said that multi-core is closer to a gimmick. Studying the performance and internal structure of each core can truly reflect the performance of mobile phones, and the core of Intel X86 is compared with ARM's single core. It is not on a horizontal line.
High performance also has high battery consumption behavior. At present, the nuclear war of mobile phones needs to be cooled, and the external environment is not better prepared for the rapid increase of the number of cores of mobile phone chips.
