Considering the speculation that the next iPhone will be using the iPads A4 SoC, I thought this post would be more relevant here than over on the iPad boards. Has anybody done any benchmarking of the iPad vs the 3GS, particularly app loading speed? If anybody has any links, or has done any benchmarking themselves, please share it here. I'm very interested to know what kind of performance we might expect out of the iPhone 'HD'. Bear in mind, I'm still using my sometimes painfully slow 3G, so even a 3GS feels snappy to me, but how does the A4 really perform? How big of an upgrade really IS the A4?
