Qualcomm quad-core mobile CPU performance beyond the historical product

August 17, Qualcomm organize media events in Beijing, presented to the media and gave details of the on-chip Snapdragon S4 Pro - APQ8064.

Qualcomm Snapdragon APQ8064 chipset chipset using the 28-nanometer process the Krait architecture quad-core CPU, clocked at up to 1.5GHz-1.7GHz, integrated Adreno 320 graphics chip. Speed ​​performance, graphics processing, power management, APQ8064 is the leading standard for mobile processor.The currently snapdragonS4 has been used in telefonos moviles and mobile devices.

The APQ8064 using quad-core the Krait architecture processor, according to official Qualcomm, the architecture performance is equivalent to the level of the Cortex A15 architecture.Its integrated Adreno 320 graphics processing chip called the most powerful mobile graphics chip, compared to the previous generation GPU Adreno 225, about four times performance improvement. And in addition to the Adreno always have unified shader architecture advantage, Adreno 320, there are a number of innovative technologies, such as FlexRender, support GPGPU, OpenGL ES 3.0 support to further improve performance and reduce power consumption.

In addition to the advantage of the 28-nanometer process, in terms of energy consumption, Krait architecture asynchronous multi-core can significantly reduce power consumption. By testing on the phone with moviles android, it is multi-threaded task performance, especially synchronous multi-core CPU needs to work in the same frequency and voltage of each nuclear Krait CPU architecture to allow four CPUs may be made according to the task at independent frequencies andvoltagesBrowsing the web video, the Krait architecture dual-core CPU than previous CPU power saving of about 33%.

In the event, Qualcomm exhibition the SnapdragonAPQ8064 mobile development platform, which is a Tablet PC with Android 4.0 operating system, screen resolution of 1366 × 768 pixels, in addition to the 1.5GHz APQ8064 quad-core processor, alsowith 2GB RAM, and a 12 million-pixel camera, fully embodies the group's performance of this chip. From the field, we use the some evaluation tools test results, overall performance, graphics performance, and other aspects of browser performance, which are at the level of the top mobile terminal.
