Re: iPhone Event - 4/10/2011 - Read post #1 before asking questions
I don't understand the quoted performance increases though? Up to 2x faster performance (not sure where the "A5 Chip x7 faster than iPhone 4" from the OP comes from?) on tasks? How is that possible? I tap on Safari and it launches instantly. I tap on Mail and it launches instantly. I tap on Calendar and it launches instantly. Will people actually see a difference?
Basically the A5 processor is dual core version of the A4 processor, give or take the CPU is the same, just with 2 cores. Think of it like having 2 A4 processors inside, simplistically you can say that you have up to 2 times the processing power. Realistically you don't, because you have to deal with threading & concurrency which means that only in the most ideal of situations will you be able to leverage the performance advantage.....it will be faster, but on average it won't be anywhere near the 2x max.
Then they mention up to 7x faster graphics performance, I have Infinity Blade and it never skips a beat. Flawless. Not sure how the graphics can be 7x faster. Will be nice to see a 4 and 4S running side by side for comparison.
The A4 & A5 processors are SOC, they include the CPU & graphics engine (plus a whole load of other stuff) in a single chip. The graphics engine in the A5 is substantially faster than the A4. So although infinity blade may run at a nice high frame rate, the next generation of games will be able to take advantage of the higher graphics performance to produce higher quality and better frame rates than is possible on the older SOC.
