I'll bite, what is customized about the PowerVR implementation in the A9? How does it compare to whatever PowerVR's reference implementation is?

- Steko 11y agoI'll bite, why do we need to know Apple's trade secrets when we can arrive at grandparent's conclusion by glancing at GPU benchmarks? http://images.anandtech.com/graphs/graph9820/79253.png http://images.anandtech.com/graphs/graph9820/79253.png http://images.anandtech.com/graphs/graph9878/78726.png http://images.anandtech.com/graphs/graph9878/78726.png
- cromwellian 11y agoBecause you're comparing Apples to Oranges, comparing PowerVR to Adreno/Mali chips. The original post claimed Apple modified a way to make PowerVR much faster than the off the shelf PowerVR IP that any phone manufacturer/SoC supplier can access. But the reality of the 'secret sauce' is pretty a banal. They basically just stamped down more clusters, and introduced an interconnect. This is not something other vendors haven't done in the past. They didn't make major architectural changes. It would be like claiming that taking two Intel CPUs, and arraying them with a custom bus means you've changed the design of the CPU cores.
