With the idea of the plane-table Of apple of iPad, the company Of apple limited to communication, that as the basis of apparatus platform was assumed it [chipset] Apple A4, which is been system on the chip. Clock frequency was declared by 1 GHz. Later it was unofficially confirmed that into the composition of apparatus platform enters the graphic processor Of powerVR SGX. The presence of this chip by confirmed different sources and is not denied by company by producer. With that so, until now, of any official information about the elements of entering in strictly in [chipset] Apple A4 it does not communicate. There are no strange information sources whatever. The resource Of ars Of technica proposes its view on however, the fact that inside iPad.

In the opinion the representatives of this resource, Apple A4 not that another as one processor Of cortex A8, deprived moreover of the majority of functions originally in it located. The limitation of system was produced consciously, since the engineers of company originally knew that the large part of the functions will remain uncalled-for. Since iPad is originally deprived of camera, possible to assume that the blocks, which correspond for interaction with the photographic module were withdrawn. In the opinion the experts of presenting Ars Technica, in the composition Of apple A4 were included the following elements: graphic processor, processor for the work with the applications, the interfaces of memory (DDR and NAND), system elements, the elements of safety and the minimum collection of connectors.
