Apple's A6 Chip Confirmed to Carry Triple-Core Graphics
The [SGX 543MP3] is sort of the best of both worlds. You don't take a huge die area penalty and at the same time don't run at a significantly higher frequency, and you can get to that same 2x value.AnandTech has now followed up with a new report based on fresh images from UBM TechInsights showing the layout of the A6 with three graphics cores as had been predicted.
The [SGX 543MP3] option is the most elegant and likely what Apple chose here.
The image above shows two 32-bit LPDDR2 memory channels and three GPU cores. We're likely looking at a PowerVR SGX 543MP3 running at 266MHz.More information and analysis on the A6 will undoubtedly be forthcoming as UBM TechInsights continues its work, but the first glimpse inside Apple's custom chip design for the iPhone 5 demonstrates how the company has been able to balance processing power needs with die size constraints to achieve significant performance gains for the iPhone 5 compared to its predecessors.
UBM estimates the die size at 95.04mm2 and the manufacturer as Samsung.
