I seriously can't imagine Steve omitting this from the keynote if true.

But if it *was* 512 that'd be super news and the last push needed to upgrade.
 
fake

I m sure if it was 1ghz and 512mb of ram .. steve would be presenting to everyone ... he did not mentioned because it is not 1ghz and 512mb of ram. It would be awesome if it is true specs thorugh.

Edit: I was one minute slower!! Anyway .. i expect (want!!!) a bump of hardware, at least, to 800mhz and 300mb of ram.
 
I am curious how many of those clamoring for 512 MB can actually provide a usage case where they need it or they're just asking for bigger numbers for the sake of them.

Just like eight megapixels is automatically superior to five, no matter the quality of the optics. :D

Apple NEVER talks specs. Go watch the iPad keynote, we didn't know the A4 clock speed for some time. Don't think Apple talked specs when they announced the 3GS either. Point is, Steve wouldn't have said anything if it is true.

You dont need it in a phone like the iPhone that doesnt multitask, have live wallpapers, auto updating weather/sports widgets or heavy programs like Google maps with navigation. You can run the iPhone OS just fine on what it already has.
 
Amazing. Nobody seems to care about performance. It's all about hype and numbers. Bigger means better it guess. :mad:
 
Likely almost the exact same. It's the peripheral I/O support type chips that are likely different. It will also have its own special power management chip. The reason that the A4 is 1 GHz vs. 3GS's speed is that it's manufactured on a 45 nm process compared to the 65 nm process or the 3GS. This allows it to be clocked higher.

Ding Ding Ding. We have a winner. The 45nm process is more power efficient than the 65nm, allowing Apple to clock the A4 higher while maintaining battery life.

The fact that Steve did'nt say 1ghz A4, really makes me think it is clocked down.

If it makes you feel better, Apple has never confirmed the A4 runs at 1GHz on the iPad. Apple never talks specs. They didn't on the iPad, the didn't on the 3GS, and they won't on the iPhone 4. Doesn't mean the A4 is underclocked.

I believe the 3gs is also a cortex a8 generation code, so mhz for mhz should be near enough same, excepting perhaps for any tweaks in size of cache and such.

A4 is custom silicone. Check the wiki page for differences from traditional ARM architecture.

http://en.wikipedia.org/wiki/Apple_A4

The A4 has distinct differences that allow it to run at a higher clock rate than the regular A8 core. The SoC Apple has setup on the A4 make it significantly more efficient.

One observation I'd like to note, all of the tech sites report the new iPhone is as fast as the iPad in their hands-on previews. Take that for what you will, but sounds like 1GHz to me.
 
People tend to not understand that ARM is simply an IP company. While they create the instruction set and define the major architectural units, the specific design and fabrication is completely up to the licensee.
 
The iPhone 3GS was all about speed. Thats why they mentioned it then. Clock speed and RAM really doesn't matter what so ever on a phone so why fuss about it?

RAM does matter on a phone. It mattered in the 3G vs. 3GS, it mattered in the Palm Pre vs. the Palm Pre Plus, and it matters in the HTC Hero vs. the Nexus One. If these phones are going to be multitasking and running more robust and advanced programs, they are going to need RAM just like computers do. I want to see what kind of apps developers could make with 512MB of RAM, I am sure it would be impressive. What is "enough" for June of 2010 might not be enough for December 2010, or June 2011 or 2012.

"640K ought to be enough for anybody."
 
Excuse me, everyone, what is Ram?

http://en.wikipedia.org/wiki/RAM

Random Access Memory (RAM) provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM.

If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.

It was specifically stated during the ipad keynote that A4 is running at 1 ghz. I personally would like 512 of ram but don't see apple doing it if they didn't on the iPad. They'll throw it on the iPad next march, and then iPhone 5 will have it.

Sure. Preloading Safari tabs for transient travel through areas with no connection. I'm lucky if I can keep 3 open without it needing to reload, or crash while switching even on the 3GS.

When I had a jailbroken 3G iPhone I could never keep a backgrounded audio stream open for long since it'd crash due to lack of RAM. The 3GS made all the difference in the world, but as I said above doesn't stand up as well when Safari enters the picture.
 
Even if the memory is the same as the 3GS, and the clock speed is less than 1GHz, I think we're going to see performance increases.

Why? Because this is Apple's chip, using Apple's hardware, running Apple's software. That's what sets the entire lineup of Apple products apart from everything else. They engineer, design, and produce [most of it] using their own specifications. That's part of their entire product philosophy.

So the previous processors in the last iPhones did the job, but now they've got something custom made to exactly what they want, and their software is written for the hardware they produce. They have full control over it, which is something other companies can't quite claim yet.

Not to go too far on a tangent, but think about the PC world [i'm a PC guy btw, got my first mac last year]. I reinstall Windows, then I have to go and download drivers from multiple sites to make the hardware work, then go to another place to get the software that does what I want. All from different vendors or companies. Now think about Apple. You install OSX, there are no drivers to install [unless you have custom equipment], and Apple produces an array of utilities that can accomplish what most people want, written specifically for OSX so it runs efficiently.


I may be overhyping what I've read about the A4 chip, but based on what I've read, if you designed the silicone, and you wrote the software which operates on it, it's going to be pretty darned efficient.. to the point where doubling the memory and upping the core speed may not be required.

Remember that the iPhone uses flash memory; not a convential HDD. Even if there is virtual memory or a page file on the storage chip, reading/writing to such a file would have a smaller impact on performance than that of a spinning HDD.
 
When readers of CoolInfoGraphics.com (source of graphic) challenged the 512MB saying "the A4 only has 256MB onboard," there was no response from the site editor or webmaster.

I agree that Apple's vertical integration has its benefits, but it also has its downsides too. Apple purposefully keeps slowly upgrading components so that you'll want to buy every year. They could have put 512 in, and it wouldn't have hurt anything and would have helped with safari issues. But they know that next year when they put it in we'll say, well, that's a good reason to buy another. They control all of this so we don't have a choice.

Also, sorry to burst the A4 bubble but it's just a rebranded chip from Intrinsity. Apple didn't design it, at least not the CPU. I think in coming years they will have chips that they built entirely in-house though.

Safari not reloading tabs is a feature of iOS 4, as documented in the iOS 4 features thread on this forum.
