Will Apple's A4 iPad 1GHz chip be used for the iPhone?
The Apple A4 1GHz processor that is powering up the iPad was the subject of some positive comments by those who were able to get a hands-on view of the tablet. Adjectives like "zippy", "fast" and "snappy" were mentioned in most reviews about the iPad and part of the reason for the speed was the Apple A4 which was produced in-house by the Cupertino based company. The 1GHz speed matches the speed of Qualcomm's Snapdragon which is currently the fastest processor used on cellphones like the Nexus One and the HTC HD2. Apple's A4 chip also provides 720p video playback and allows for 10 hours of battery life on an active day.

Since the Apple A4 was designed for mobile devices, and with the similarities between the iPad and the iPhone, it wouldn't be a stretch to imagine the 1GHz chip powering a faster generation of Apple's touchscreen phone. Nathan Brookwood, an analyst at Insight 64 says, "There's really no reason why a chip with this kind of characteristic wouldn't make it in the iPhone." Apple could even underclock the A4 in a new generation of iPhone which would allow for greater battery life. Currently, the iPhone 3GS uses an Arm based system on a chip produced by Samsung clocked at 600MHz.

I'm absolutely sure they will use the A4 in the next iPhone which is a VERY great thing. I love the snapdragon on my Nexus One, it really makes a huge difference! Actually i was more impressed with the A4 than the iPad. Thats one slick chip.

I doubt Apple bought PA Semi just to make the iPad...

I would hope so... I have a feeling 1Ghz is going to be the default proc speed in the near future. It wouldn't surprise me that late this year/early next most smartphones will have a 1ghz chip. If apple were to come out with another iphone on a slower processor, I think they would fall behind in performance (at least until they refresh)

but apparently, apple doesn't need mind blowing power for their products to run smoothly. So their next iPhone could have only 800mhz and still be hanging out w/ the rest.

I'm absolutely positive the A4 will power the next iPhone. As soon as I seen it I knew it. Buy o fear apple will underclock it for battery life. :-( i hope not. Then again, one of the major advancements of the A4 is to run the tablet with all it's processes 720p video included, and maintain the battery life of 10 hours. I'd like to know if the 10 hour rating is just for the wifi version or applies to the 3g version With an always on signal as well. That will tell the real story.

I was thinking this same thing, myself. If the iPad actually does perform this well, with that huge screen, running that kind of video, then I would think that there would be even less of a need to underclock the A4, to save battery in the next iPhone. But that's just a guess, as I'm not well versed in chip-related variables on battery performance.
