As part of its report on Apple’s custom ARM chip design for the A6 discovered in the iPhone 5, AnandTech speculated that the enhanced photographs performance within the iPhone 5 used to be done through the usage of a triple-core PowerVR SGX 543MP3 images processing unit (GPU) fairly than doubling the clock velocity of the dual-core SGX 543MP2 discovered in the A5 or the usage of the quad-core SGX 543MP4 discovered within the A5X for the 0.33-era iPad.
The [SGX 543MP3] is kind of the best of each worlds. you don’t take a huge die area penalty and on the similar time don’t run at a significantly greater frequency, and which you can get to that very same 2x value.
The [SGX 543MP3] option is the most stylish and certain what Apple selected right here.
AnandTech has now adopted up with a new file according to fresh photography from UBM TechInsights exhibiting the structure of the A6 with three pix cores as had been expected.
The image above displays two 32-bit LPDDR2 memory channels and three GPU cores. We’re possible taking a look at a PowerVR SGX 543MP3 running at 266MHz.
UBM estimates the die measurement at 95.04mm2 and the manufacturer as Samsung.
extra information and analysis on the A6 will definitely be drawing close as UBM TechInsights continues its work, but the first glimpse within Apple’s custom chip design for the iPhone 5 demonstrates how the company has been in a position to balance processing energy wants with die measurement constraints to achieve significant efficiency positive factors for the iPhone 5 in comparison with its predecessors.
