So, with the next iPhone rumored to have a cortex A8 processor, and the iPad with an Apple A4, i started to think, which one is better, faster? I thought maybe the A4 because it's newer, but then i remembered that the A4 was bascially the A8. What do you guys think?
 
it's the same thing

the way ARM works is they license the instruction set and some other IP and it's up to you to design your own CPU around it. the AR is a A8 core CPU with a lot of the circuitry that the 3GS version has removed since it's not needed. this is why the battery life is so good

But with the rumors the way they are now, would that make the new iphone the same or faster than the ipad? 3gs?
 
I heard what might make the next iPhone faster is that its rumored to have 512mb of RAM as opposed to the iPad's 256mb. As an iPad owner, I'd be pretty pissed if that's true. If you can cram 512mb of RAM into a tiny iPhone case why not a relatively huge iPad?
 
It all comes down to what speed each is clocked at. We don't know what the iPhone is going to be clocked at, but it will probably not be at the same speed as the iPad due to battery life concerns.

Well they're not going to make the new iPhone slower than the iPhone it's replacing.


I expect, and this is only a guess, that it will have the performance of an iPad, which is fine. It costs more than my iPad and is coming out later so it's fine if it has more RAM and similar or better performance. Kinda cheap of Apple not to put 512 in the iPad though, but that topic has been beaten to death.
 
A4 is a SoC - System on a chip.

Imagine as A4 being a motherboard that you slap components on like Cortex A8 CPU, PowerVR SGX540 GPU, 256MB RAM and so on.....

iPad has a 1GHz Cortex A8 if I'm not mistaken.

iPhone is rumoured to have the same A4 SoC with 1GHz Cortex A8, PowerVR SGX540 and maybe 512MB RAM.

This.

The A4 has a Cortex A8 in it.

What would be awesome is if Apple came out with a newer chip (A5?), that used a multi-core cortex A9 instead of the single-core A8 and paired it with 512MB RAM. That'd quiet all the nay-sayers in a hurry.
 
I'm having a hard time remembering where the 512mb rumor came from? link?

what makes us think it will have 512mb?

I Can't see 512mb of ram on the phone (I very much welcome it though)
 
Which is better, a Mustang or a Ford?

Ford kicks the Mustang's butt!!! :p

They should call it the S4. ;)

Digitimes

depends if they make any more changes to the CPU. with the same A4 as in the Ipad it will probably have much better battery life than my 3GS.

apple never makes big changes at once in a product. they will try a new product or upgrade by making a small change in an existing product. Mac Book Air is an exception, but that led to the idevices and other unibody Mac Books.

the new Macbook now has a bigger battery, so expect to see it in MacBook Pro's in the next refresh. Apple bought a new model from the company that sells it to work out the bugs. same with the 27" iMac LCD's.

A4 is an experiment with making their own ARM CPU. Expect it to find it's way into other products as they work out the bugs
