Apple is claiming that its new A8 system-on-a-chip, which will feature in the iPhone 6 and iPhone 6 Plus, is massively superior in terms of processing power than previous processors, and AppleInsider reports today on how Apple has managed to achieve this.

According to AnandTech, it is likely that the A8 is equipped with Imagination’s 6-core PowerVR Series6XT GX6650. MacRumors says that this is the only PowerVR part that would be able to achieve the degree of performance improvement that Apple is claiming as well as supporting ARM’s Adaptive Scalable Texture Compression (ASTC), which developer documents reveal is a feature of the A8.

ATSC is apparently a new standard for texture compression that means that GPU manufacturers are able to make their chips more efficient in terms of power, while still maintaining high performance levels.

The codec is able to compress almost any texture, of any format, with various bitrates depending on the required levels of performance.
