iOS 4.X for iPad already here

Don't you read!!! The amount of pixels is just one of the things the RAM stores, there are MANY other features such as Cameras, Gyroscopes and many sensors that the iPhone has and the iPad does not have. You amaze me.

OK, y'all correct me (as I know you will) if I'm wrong:

Isn't it the VIDEO RAM (VRAM) that stores the pixels? I'm sure the system RAM assists, but its the GPU and its VRAM that do the majority of that work.

Problem is I can't find ANYWHERE about the VRAM for the iPad's GPU (an SGX core, btw). Maybe it DOES borrow system RAM, like "integrated graphics" on desktops/laptops...

I do read but you're not making any sense. You're argument seems to be based on the idea that the iPhone 4 needs to have 512MB of RAM because it has a camera and a gyroscope. And that the iPad only needs 256MB of RAM because it lacks those things. I have no idea why you think that those 2 extra features need more RAM than the entire OS. If the camera needed that much RAM, then none of the previous iPhones would have been able to have one.

All I know is that the iPad runs out of RAM, frequently, but the iPhone 4 does not. The logical conclusion to this is that the iPad is underspecced in the RAM department, or, the software is currently poorly optimised.

No reason they need a beta. As far as i remember, no major iOS update has had a beta - only the minor versions get it?

There have been pre-releases of every system update. The beta stage allows for developers to ensure that their software fully supports the new operating system.
 
So for everyone who is dogging iOS 4 for the iPad then maybe you shouldn't upgrade.. I'm sure Apple will implement iOS 4 on the iPad in an efficient manner that doesn't over-tax it's system resources in a very noticeable way that most casual users will complain about. Any OS will grind to a halt if it's resources are being strained... I think most of us will only have 3 or 4 apps at the most running at a time so.. I'll be content if I can run Pandora, Safari, GPS app, and say maybe Keynote- not that I would need to run those apps at the same time, but I think if you can run those particular apps at the same time without any lag or lockups then iOS 4 will be successful.

Fingers crossed Apple can get it right!

This notion that a "beta" of iOS4 for the iPad is required doesn't make sense. There was no public (announced) beta of iOS3.2 on the iPad... Apple did their testing in-house and in secret. No reason why iOS4 should be different.
Click to expand...

The beta of iOS 3.2 (then called iPhone SDK for iPad) was released around the same time that the iPad was revealed (January 2010).

No developers outside Apple had hardware to test on, but they were able to run their iPad apps in a software simulator.
 
jobs said fall for an update and when he says fall he means september 29 lol, but the thing is this is a big update and for all we know they could of added like 20 new features and api's. unless they only added backgrounding then they might not need to put out a beta. but the ipad apps will have to be changed regardless to make them run as smooth as possible. but as in previous betas they might test for weeks or only one just so the devs could change the apps, not for the stability of the os on the device itself. like i said before this all depends what they have changed, added , and if apple is confident if the new os will run on the device smoothly.

So hang on, you're saying that because the iPhone 4 has a higher res screen, it needs more RAM than the 3GS? But then you also say that even though the iPad has an even higher res screen, it's OK with 256MB RAM?! I don't even think the amount of pixels you have has any bearing on the RAM anyway, but you're making no sense anyway since your logic is faulty.

Straw man.

What he should be saying is that the most expensive feature in terms of memory is the HD camera and it requires more than 256 MB of ram to use it effectively. If the iphone 4 did not have the camera, it would not have 512 MB.

But what relation does that have to the iPad not having enough RAM?

Or more simply, answer this question; With iOS 3.2.2, the iPad frequently runs out of RAM. Why is that?

That is also baloney. I'm fairly certain the camera would run just fine on 256MB. The iPad and it's lack of RAM drives me crazy, though. The Safari tabs nonsense is irritating as heck. The iPad IS under-specced.

Yeah, idk about how much memory the camera and such on the iPhone 4 use up or anything. But I know for sure that the iPad got the short end of the stick when it comes to RAM. Typical Apple - underspeccing a 1st gen device.

I reckon they gave the iPad the same specs as the iPhone 3GS so not to give away things in the iPhone 4 - so that the iPhone was the main device device and then iPad followed it, with basically the same specs, with nothing extra...

And the iOS4 SDK for the iPad has been available for quite some time too, because it is the same SDK as for the iPhone.

Apple said:
iOS SDK 4 includes a complete set of development tools for creating applications for iPad, iPhone, and iPod touch, including the Xcode IDE, iPhone Simulator, Instruments, Interface Builder, and more.

There's a benchmark on the web between the iPhone 4 and iPad showing the iPad coming out as faster I believe, let me try dig out the link.

Edit: http://www.geek.com/articles/mobile/iphone-4-is-slower-than-ipad-benchmarks-indicate-20100623/ however, as there is no ios4 for iPad yet, the comparison is not quite fair.

That's not completely true, starting with the fact that the iPhone has retina display which adds the small device 80% of the pixels that the iPad has, and the iPhone also has a Gyroscope and many other features such as the Camera which require more RAM memory, so the iPad, for having less amount of features has a great amount of memory. The amount of RAM required does not depend on the size of the device, but the features that require it.

Its 78% pixels of the iPad, not 80%. There is not such thing as a Retina Display. Its just a cheap chinese screen that has more pixels that the older cheaper crappier display on the iPhone 3GS/3G/Original. There IS NO SUCH THING AS A RETINA DISPLAY! ITS A MARKETING TRICK!

"iOS SDK 4" is different from "iOS 4". The latest iPad software available is 3.2. There is no newer version available for developers, unfortunately.

The higher pixel density is the attraction of the screen.

Because if there was there would be a ton of $99 developers out there loading up each beta on their iPad.

Everyone seems to be forgetting that the iPad (might) have a faster CPU? The A4 in the iPad is 1GHz; the version in the iPhone is 800MHz, right?
Click to expand...

/bump

Seems this salient point is being lost in the noise. The iPad's A4 chip is clocked higher than the iPhone's is...at least according to some testing done when the new phone was released.

Why not wait for the OS to be released for the iPad and test it then...rather than waste everyone's time speculating wildly.

Well of course naming it "retina display" is to do with marketing.

And what Apple means by retina display, is that generally, you can't see the individual pixels when holding the phone at a normal usage distance.

And the screen isn't crappy either..
 
Kudos to you ssdeg7 for even trying so hard to explain it to mrochester. I've just learnt to ignore those who have no intentions of learning anything.

Back on topic, apple wouldn't necessarily need to release a beta unless they release new features on the update. Jobs did say that it would be a uniform platform, so if the ipad is going to get new features, then so will the iphone and itouch.
 
Xenc said:
There's nothing wrong with that. Apple recommends that you test your applications on each beta OS as they are made available.
Click to expand...

I agree. Just saying if it was available to devs a ton of folks would sign up just to try it out.

Cheers,

I don't think it would be clever for Apple to release new software without first informing their developers. Imagine if your popular app suddenly loses functionality or performs inadequately due to a new iOS update that you knew nothing about? It would create a lot of unhappy customers, affect your App Store rating and directly harm your revenue.
