Kenzo iPhone Case: Power consumption reduced by half ARM core Mali 470 new graphics GPU

　　Wei Feng network on October 21, a few days ago, ARM released a new series of Mali graphics core Mali-470 GPU, main wearable device and Internet fields. Many machines are familiar with ARM Mali-400 GPU because the GPU is widely used in entry-level smart phones and smart watches, and has just released the Mali-470 GPU is his successor.

　　Since introduction of the ARM, Mali-470 GPU power consumption significantly reduced, only half of the Mali-400 GPU, which means that it can be used for a wider range of scenarios, especially the limited battery capacity of the equipment, or the product is strictly limited to temperature, such as the wearable device. But performance may be more disappointing, because the Mali-470 GPU Mali-400 GPU was only the same performance, only have an advantage in terms of power consumption.

　　But, Mali-470 GPU in some details aspects also for has upgrade optimization, like upgrade has internal vertex processor (Vertex Processor) and pixel processor (Fragment processors) component, makes energy efficiency sharply reduced, and micro-schema of improved also makes its can more full of mobilization clock door control (Clock gating), and up extended to more big core of configuration is can using power door control (Power Gating) to achieve better power management and thermal management.

　　Mali-470 multicore support extension with Mali-400 the same, only supports single-to quad-core extension, and Mali-450 scales of 1 to 8 cores. How many nuclear nature is in factories and ARM when the order was discussed core can cover a variety of different number of market demand, price and performance, if you really need to support high resolution product market, nature is the highest of the 4 most excellent core Mali-470 GPU.

　　In addition, Mali-470 GPU die size smaller than Mali-400 GPU, CPU cores into smaller SoC integrated chip, chip size by the manufacturer itself. ARM believes that Mali-470 Cortex-A7 and Cortex-A53 CPU and GPU cores can form today without sacrificing performance but the lowest power consumption SoC processor, screen resolution can support from 640x640 to 1080p/60FPS/32bpp.

　　According to ARM the expected Mali-470 GPU will be applied to the renewal of a series of low-power products, including wearable devices, household and automotive products, as well as the requirements of graphical user interface of embedded products and so on. Mali-470 API support GPU OpenGL ES 1.1/2.0 is precisely in line with the minimum requirements for Android Wear smart watches, while OpenGL ES 3.0 is the latest standard, but support is not worth the extra features and cost you more power, and OpenGL ES 2.0 is official is used in a variety of products, so chip manufacturers need to upgrade product manufacturers to provide chip is very simple.

　　Front says Mali GPU people look familiar, because chip makers have low-end Utgard a schema used to design chips for smartphones in the market, such as mediatek MT6592 eight-core processors, using the Mali-400 GPU. In fact, the mediatek chip smart watches and Samsung adopts ARM Mali GPU, its excellent characteristics of ultra low power consumption. It's not that Mali has no high-end GPU, you can see the integration of Mali T760MP8 Exynos 7420 using Samsung Galaxy on the S6, and Samsung also signed a long-term cooperation agreement with ARM.

　　According to ARM,Mali-470 will be a long time before they will enter into consumer products, latest GPU chip partners is expected to use the research and development of finished chips will not be shipped until the end of 2016, and the first half of production until at least 2017.
