  • Apple's A8X SoC Discovered to be Running on Customized GPU and 3-Cores

    According to a new analysis of the chip that powers the iPad Air 2, the A8X SoC, Apple appears to have moved to a semi-custom design for the graphics processor, all while employing an unusual triple-core CPU. The GPU found in the A8X isnít like the previous parts from the long-time partner Imagination Technologies that the previous chips used to rely on. Instead itís a design that comprises of essentially two Imaginationís 4-core G6450 GPUs.

    For those of you who didnít know, Apple is a minority investor in Imagination and licenses their GPU designs. As a result, Apple is allowed to create customized versions of the parts which can be included in the A-series chips.

    In addition to the GPU being custom, the A8X was found to only have three physical CPU cores. Its tri-core design was already known but previously, many speculated that the design would be that of a quad-core processor with one of the four cores being disabled. The A8X contains approximately 1 billion more transistors than the A8 which powers the iPhone 6 and 6 Plus. The Cupertino California even doubled the processorís L2 cache to 2 megabytes, increased the clock speed to 1.5 gigahertz and moved to a 128-bit wide memory bus, all of which improve the output of the chip significantly.
