Apple to reportedly double 'iPad 3' RAM to 1GB

post #1 of 46
Thread Starter 
A new report claims that leaked debug photos purportedly from Apple's third-generation iPad show that the device will sport 1GB of RAM, double the amount of its predecessor.

On the heels of recent reports that Apple will increase the RAM in its upcoming iPad model, a hacker and iPhone jailbreaker known as "Chronic" offered up a specific number: 1GB.

Leaked debug photos allegedly of Apple's next iPad that surfaced last month showed a line of code that read "vm_page_bootstrap: 244276 free pages and 8396 wired pages." By multiplying the number of free pages by the size of a page (4,096 bytes), the developer deduced that the device will have 1GB of RAM.

Apple's second-generation iPad, released last March, carried 512MB of RAM, the same amount as the iPhone 4.\t

"Chronic" also reported earlier on Tuesday that the golden master build of iOS 5.1 has passed Apple's internal quality assurance testing and is set to arrive soon with the addition of two secret features.




Speculation surrounding the next-generation iPad has surged in the run-up to Apple's media event, scheduled to take place on Wednesday. The so-called "iPad 3" will likely boast a 2,048 x 1,536 pixel display, a faster processor and 4G LTE. There has been some disagreement, however, on whether the new processor will be a quad-core A6 chip or an A5X dual-core chip. Recent reports have pointed to the A5X dual-core option as most likely.

A pair of reports have also claimed that Apple will set aside its current numbering system and call the new device the "iPad HD."

Might have better luck with this here: "Is anyone else worried about the extra power draw of the RAM, too?"

Between potential quad-core, LTE, and the doubling of RAM, will we have any battery life left?

If reports are correct, it's about .81 mm thicker, or at least, the back is. So that leaves a lot of extra room. Some might be used for the LTE chip, if present. But thats not appreciably thicker from the pics I've seen of it. So what else could the extra space be for? I imagine a thicker battery.

I don't know how thick the present battery is. If we did, we might have a fair idea of how much more power this one contains, assuming it isn't a better technology on its own.

But, only the 3G/LTE models need more power. The WiFi models don't. So if the battery is more powerful, and we just have a WiFi model, or have 3G/LTE turned off, we should get a good deal better battery life. A fair tradeoff, I suppose.

Keeping 512 was pushing it in the iPad 2 IMO, its a fast device and so even more annoying when you get slowed down by having to reload tabs in safari or have sluggish switching to and from larger apps. Keeping it for the 3 would definitely be a no-no with 4x the pixels.

If it has HiDPI display, which seems like a given now, 1GB is surely expected. I figure that will probably hold for 2 years until 2GB is feasible.

As for power draw, it's small but it's constant. I hope with all the new HW needed for that display that it gets at least the same usage times as before. I'm okay with a thicker and heavier unit if means longer life.

Probably not. It's going to suck (all the battery life, I mean). Apple will launch a product that will be a battery hog and watch their sales hit the floor.

Seriously, though, I think I'll skip the hype this go-'round. I did it last year and it was a headache. I'll wait a month or two before I even consider buying one. Not that I don't want one, mind you. Just don't want to be a part of the frenzy this year.

Brainstorm: Could the incessant "iPad mini" screens actually be for... wait for it... Car stereos???

I'd kill for an apple car stereo that will AirPlay from the iPhone in my pocket without me having to noodle the phone. In fact, take the calls, too, and voice text.

The only challenge I imagine is the many different kinds of stereo internals in cars... If that's actually true. If it's not an issue, it's a slam dunk.

It is a misnomer that LTE will use more power. First generation LTE devices used *two* radios, one for LTE and one for 3G(evdo). This resulted in higher power consumption. However, iPad 3(HD) will be using a new Qualcomm chipset that integrates the two radios. LTE power consumption will not be higher than 3G. LTE also have power saving modes that allow iOS to turn off the uplink radio (for example) when the user is just reading content.

http://www.snet.tu-berlin.de/fileadm...max_eberle.pdf

Doubling the RAM won't have an impact on power either, because it's likely a single chip regardless, and probably at a higher density (nm) than the iPad2 memory.

Quad-core and the new screen (which requires dual lighting bars) are the only things that might really impact power consumption. However, as is rumored, I would expect an enhanced dual-core rather than a quad-core in the iPad3. The slightly thicker case of the iPad3 can probably be attributed to the new camera assembly, but I would expect Apple to make lemonade out of lemons and use the extra space for a slightly bigger battery.

I think the new iPad is going to be called 'iPad DH' in honor of the American League.
post #10 of 46
also....if the one GB of ram theory proves to be true, wouldn't that also indicate that the A5X processor is in fact the iPad 3 core processor? the line before it states /DEVELOPMENT_ARM_S5L8945X . This seems to indicate, providing "chronic" is a reliable source that tomorrow will show us an iPad 3 with 1GB of RAM and a dual core improved graphics A5X processor. Seemingly the retina display has been proven to be true, lets all just cross our fingers for full 4G support.

It was a shock that the iPad 2 RAM was 512. I welcome 1GB but it would have been absurd for another iteration at 512. I wish Apple wasn't so stingy on RAM.

I'll bet you a $25 iTS card that LTE will be lower than the stated '3G' usage times.

I think a dual-core chip is possible, too. Do the dual lighting bars need to be used for all panel types of this density? There is talk of IGZO but I think AH-IPS is plausible.

More RAM is almost always good for power consumption for a very simple reason: you need way more power to reload assets that you have to regenerate from closing an app or downloading data from a network resource (especially if that resource involves a cellular radio instead of WiFi) than keeping that data in RAM.

When you have to reload data from the Internet, the OS need to turn on the WiFi/cellular radio, check to see if there's a connection, pray that connection is good and packet loss is low (there is always packet loss), hope that servers aren't acting up, then download that data and keep the radio on for instant availability for several minutes before turning it off again when in sleep. This process sucks battery power.

Some may then ask why the iPad 2 only had 512MB of RAM with all of these wonderful benefits. More RAM costs money to Apple. Shorter battery life does not.

I don't think your argument holds for non-disc drive reads which is why Apple has been stingy with RAM.

Now when it comes to page viewing having a page reload every time you switch between tabs does drain the power faster and slow down usage for obvious reasons. I returned my first iPad because of that very annoyance with Safari and 256MB RAM.

Here's an old article that details why RAM in these small devices can't just be added willy nilly...

LTE Chip is built-in to the 3G chip. There is plenty of room for expanded battery tech.

From what I can see only the MDM9600 is available to vendors. That's the 45nm version with LTE, meaning the 2nd gen LTE. The 28nm MDM9615 isn't slated until Q2 which is pretty close to the expected launch date.

It seems like Apple and Qualcomm's relationship could bring the MDM9615 in with the iPad HD but how certain are we that Apple will introduce LTE outside an iPhone? I don't think any iPad has gotten cellular HW that was better than the iPhone came out that same year.

thanks for the link to the paper.

LTE uses OFDM while 3G uses WCDMA. at higher bit rate, i would guess that LTE would consume more power.

instead of using 2 radios, QUALCOMM combines them into 1 radio?

The new Qualcomm chip actually integrates 6-radios into one: LTE FDD and LTE TDD, HSPA+/UMTS 3G, EVDO 3G, GSM, and CDMA.

LTE has more power-saving modes than 3G. If power-saving modes are not taken advantage of, LTE will consume more power than 3G. But proper power-management could see LTE with a slight advantage over, or at least on par with, 3G.

Light bars are needed on LCD-based panels. AMOLED does not need lighting bars. However, OLED is power-hungry in exactly the use-case that Apple wants most. From wikipedia:

"OLED display consumes 3 watts while showing black text on a white background, but only 0.7 watts showing white text on a black background."

Because many people are viewing web pages, mail, documents, etc. that are 90% dark text on a white background, the power profile of OLED is terrible. So when people complain that Apple isn't using OLED for any other reason than power, they don't know what they're talking about.

Apple is waiting for OLEDs to mature enough to bring down the power-consumption. Until then, I doubt you'll see OLED in Apple's products.

About time. The RAM was the one feature of the iPad that people had legitimate concerns about. Simply because it made the experience sort of sub optimal, by forcing Safari reloads.

Of course, this is a double edged sword. I hope Apple still keeps a tight rein on allowing minimal background functionality. With extra RAM, it is easy for developers to become complacent and put unneccessary features in the background! Very soon, even the extra RAM won't be enough.

The new iPad needs more ram for the simple fact the graphics resolution will be so much more higher. I think it's simple as that. For me I would like to see 2gb of ram with the proposed resolution of the new display.

Not going to happen though

Twice the ram will enable more powerful apps. It will encroach on the PC even further. I wonder if Office for iPad or a new Adobe app will be part of the keynote?

Just before last year's iPad 2 launch, my employer's IT director sent out a 'tablet review'. He briefly listed his pros and cons for the iPad/iPad 2, Playbook, Touchpad, and a Windows tablet. Only the iPads had hit the market yet, and in his wrap-up he placed them at the bottom of his top 5, saying since they were Apple products, they didn't work well with our system and their specs were too low compared to the competition.

A year later, not only has he moved to an iPhone for his personal and work phone, we're switching from Blackberrys to iPhones as corporate phones company wide, and all presentations and sales memos are now formatted to take advantage of the iPad. So much for Apple products not working well with our system.

Cnet is no better than 98% of the other mindless tech authors out there. They never understood the concept of usability or anything but simply looking at the specs. It's easy to look at specs and claim that one device is better than another. Actually using the device to see how it works requires some brains and experience - which seems sorely lacking.

Furthermore, there's a built in bias against Apple products. Read the Kindle review. If they had said it was OK for a cheap, entry level product, that would have been one thing. But the review makes it actually sound competitive.

My favorite which shows the level of intelligence of this author is:

I think you're going to be surprised.

First, the extra RAM won't have much impact. An extra 512 MB of on-chip RAM doesn't use that much power and it is partly ameliorated by the need to pull things in from Flash storage or from the cloud. It could be a wash.

Even if it has quad core, that will only have a minor impact since they may have moved to a newer process technology.

LTE shouldn't have much impact if they're using the newest chips.

And the extra thickness means that there's more room for a larger battery.

While it's possible that the battery life might be reduced slightly, I doubt if it will be much, if any.

that's how I always looks at reviews which trash apple based on spec sheets. On paper this stuff looks like it should be better. Yet if it really was better wouldn't these comapnies be selling more of their product than Apple is? I mean if Apple really is selling an inferior product at a premium wouldn't people have figured it out by now and gone somewhere else?
