A Visual History of the iPhone

> On slide 6, I'm pretty sure you mean it was *lacking* those features.

> On slide 7, technically 3G and AGPS would be considered hardware, not particularly software, as they each require a new chip to function.

> On slide 9, I'm pretty sure that the 3GS was packing a 600 MHz ARM Cortex A8 CPU (underclocked from 833 MHz), and the iPhone 4 was running an 800 MHz ARM Cortex A8; A4 chip (underclocked from 1 GHz), but the A4 was specially designed by Apple. This would also make the iPhone 4 roughly twice as fast (in clock speed) as the original iPhone which was running a 620 MHz chip underclocked to 412 MHz. However, as seen with the iPhone 3GS and 4S marketing - and performance - that the clock speed doesn't necessarily accurately reflect performance as they were both proven to be "twice as fast" as their predecessors even though both had more modest upgrades in clock speed; around 200 MHz. This can be seen in the 4S which featured an 800 MHz chip (underclocked from 1 GHz) - same clock speed as the iPhone 4 - but since it included two cores both in the CPU and GPU, showed significant performance enhancements.

Therefore, the iPhone 4 was a slight speed increase from the 3GS - considering that they had the same processor architecture, but the A4 was designed by Apple - but was in most real world scenarios a little faster at rendering and offered better power management.

It had to be said.



the figure on the last slide looks like "Windowed" 3D tech (personally a hate the NDS3D for calling it 3D)

based on what i said (though i could be wrong about what tech they are using) i think it is just the first patent file for this tech. so look for it in the iPhone5S or iPhone 6S.
