While Apple with the usual “pay attention to the experience of the product, rather than internal technical details of concept ‘has not been disclosed iPad processors used in Apple A4 detailed specifications. But industry is generally agreed that with the iPad performance oriented A4 Apple’s heart ARM processor should be based on the latest version of the Cortex A9 multicore architecture. Inspiron 510m battery , However, new technology site Ars Technica recently wrote an article claiming Founder Jon Stokes, according to his sources of information from multiple sources, Apple A4 actually more common on the Cortex A8, and the iPhone / iPod touch, and a variety of lighthouse on the market smart phones are the same frame.
The article says: “When I saw the iPad conference on video, read the relevant reports of his time, believes almost the Cortex A9 is based on the structure, and very likely for dual-core. But now it seems, A4 is only a frequency of 1GHz SoC custom-processor system on chip, and simple internal Cortex-A8 core includes PowerVR SGX GPU. Sony VGP-BPS9/B , Although the A4 Cortex-A8 core message has never been announced publicly, but I have reliable information from multiple sources confirmed. Although I can not reveal their identity, but I can say they are definitely the location of possible insider knowledge of the matter. ”
In addition, there are other media recently heard a similar report. So far, Apple iPad used in Apple A4 it is very likely one, and iPhone / iPod touch the same structure of a single processor core Cortex A8, simply because higher frequency (1GHz vs. 600MHz) it has a higher power. The acquisition of PA Semi by the companies of semiconductor Apple team of research and development, you can give the A4 a significant energy saving processor energy efficiency. PA3399U-2BRS
