Photos of iPhone 4S/5 Logic Board Suggest A5 Processor

A site by the name of AppleLeaks today posted photos of what is claimed to be the logic board from a next-generation iPhone model. The report is unsure about whether the board is from an upgraded iPhone 5 model or a cheaper "iPhone 4S" model Apple is also said to be planning to launch, but the images do add more detail to the picture</a> that is beginning to come together.




Comparing the pictures to the ones of the logic boards for the CDMA and GSM iPhone 4 models as seen in teardowns by iFixit (see steps 13 and 14), it is interesting to note that this new logic board carries a form factor more similar to that of the CDMA iPhone 4 but with a SIM-card slot also squeezed onto the board. That inclusion of the SIM-card slot on the new logic board has resulted in a reshuffling of the chip locations on the front of the board, while the back side remains quite similar to the CDMA iPhone 4 logic board.

Notably, the relatively large area on the front of the logic board designed to house the main processor for the device is rectangular in nature on the new board, suggesting that it is designed for the rectangular A5 system-on-a-chip found in the iPad 2 rather than the square A4 chip found in the iPhone 4 and original iPad. Apple is of course expected to use the A5 in the iPhone 5, but there has been some question as to whether Apple would step up to the A5 for its cheaper iPhone 4S model or continue to use the A4 in order to hold costs down.

The iPhone 5 is expected to be a "world-mode" phone capable of running on both GSM and CDMA networks. The presence of a SIM-card slot on the new logic board does indeed confirm GSM compatibility for this device, whether it be an iPhone 5 or 4S, and CDMA compatibility would come from the inclusion of a specific chip supporting the dual standards. Such a chip from Qualcomm is already used on the CDMA iPhone 4, but accommodation for a similar chip on this new logic board can not be confirmed given that the board is unlabeled.

One of the more prominent differences in the actual logic board form factor between the GSM and CDMA iPhone 4 is a semicircular cutout at the bottom of the board. That cutout fits around the new circular vibrator used in the CDMA version, a change from the vibrator used in the GSM version. The presence of the cutout on this new logic board suggests that Apple will continue to use the circular vibrator found in the CDMA iPhone 4.

AppleLeaks also posts of the battery for the iPhone4S/5, in line with photos from other sources seen several times earlier this week.

While I planned to skip this revision since I think my i4 works great (minus very minor cosmetic issues due to me), if there is a bigger screen, then I'll reconsider.

If it is on Sprint I will switch, as long as they don't decide to make a new iPhone specific plan and charge $20 to tether.

Would still sound weird to me when they would release and make a phone called iPhone 4S and make marketing with iOS 5 software and an A5 chip in it. Still everybody knew the A5 would be in there.

The iPhone 4 was left in a bar. Apparently the iPhone 5 was left in a Mafia run Italian restaurant, cause they're sending it out in pieces. Capisce?

Good point. The whole iPhone 4 leak makes the typical lead-up to Apple product announcements far less exciting in comparison.

Time marches on, new and updated components are used, are we really any better off than before the iPhone came out?

if this is the 4S, then id expect a different form factor to the 5.

However, part of me is thinking could this be the iPhone 5?

I cant wait until we see the front of the device (the only important part missing now!)

These photos are in line with earlier rumors that the next iPhone would share a common board for both GSM and CDMA versions.

Sorry to be off topic, but two days after Jobs resigns as CEO, AAPL is kicking butt (passing XOM to become most valuable company)!

There's a new iPhone coming? :p

Seems as though the spec rumors are right on.... I'm hoping for the 4s and 5 split. I think the iPhone 3 needs to be put out to pasture. It's a good phone, but the processor makes it dated.

I'm really hoping for 3D movies! :rolleyes: (NOT!)

Simply consider this. That tiny circuit board you see, that is half as wide as a phone, as long as a phone, almost, and under 1/3 the thickness of a phone, is an entire Macintosh computer running a full featured OS. Compare that to the Mac Plus board and device size and later the Cube sizes.

The A5 is probably not quite double the compute capacity as the A4, which itself was no slouch. Not as fast as a Core 2 Duo, but faster than most of the PowerPC chips used in Macs IIRC.

I suspect A6 or A7 will have compute capacity to be a desktop capable experience, whether or not that is the route they will ever go.

Intel chips are still far more capable albiet at a far higher cost, probably disproportionately so.

Side note to your side note.... I sold all my Apple stock at $160 to buy into a solar stock that was suppose to double but did nothing but sink and just got delisted the other day. Now I have almost nothing whereas if I would have went the other way I would have been very, very happy. Very bad call on my part. :(

anyone else faintly seeing "a4" on the new chip?
Of course because these two pictures compare iPhone 4 GSM and CDMA which both have an A4 chip. The new parts are not labeled and are on the top of the article. Read: It clearly states that the chip is rectangular (A5) vs. square (A4).

This could be a redesigned iPhone 4 board to use in the production of a lower cost presumably 8gb version, to sell alongside the next released iPhone. As they did with the 3GS. They could be trying to cut down on production costs, instead of producing 2 different boards for both AT&T and Verizon which could run up of manufacturing costs, they could consolidate the boards and offer it at a lower price point of one dual band unified device. Which they would offer for 100$ or many even 49$. Just my two sense:apple::apple:

its amazing how over the past week that many parts have been leaked but yet no ones put it together to make the iPhone 4s/5
