iFixit has performed their traditional tear-down of new Apple gear, this time taking the iPad apart piece by gloriously crafted piece, and here’s what they found:

The iPad’s battery has 5.5x the capacity of the battery in the iPhone! The iPad actually has two batteries wired in parallel, for a total of 24.8 Watt-hours. On average, the iPad sips just 2.5 Watts. That’s 1/5 the power of a compact fluorescent bulb!

The rear case is machined from a single billet of aluminum, increasing weight but greatly improving the rigidity of the device.

The empty void in the upper right corner is where the cellular communications board would go in the 3G iPad.

The A4 is a Package-on-Package (PoP), with at least three layers of circuitry layered on top of each other. A4 is packaged just like the iPhone processors, microprocessor in one package and two memory modules in the other package. They’re all sandwiched together in a very nice and thin PoP.

The iPad RAM is INSIDE the A4 processor package. Confirming this took quite a bit of sleuthing: we had to partner with Chipworks to X-ray the processor. The X-ray revealed two layers of RAM. In addition to the ARM processor, the A4 package contains two stacked Samsung dies.

We will be releasing a detailed analysis of the A4 in conjunction with Chipworks in a few days.

The rumored slot for a camera is actually taken up by the ambient light sensor.

The glass panel is quite thick: about 1.18 mm, compared to the iPhone’s 1.02 mm thick glass. This is necessitated by the panel’s large size.

The touch circuit design is more similar to the old 2G and early 3G iPhones than the current 3GS. Chipworks informed us that “there is so much room in the iPad that Apple didn’t need to use small chips, just the right ones and cheap ones.”

Disappointingly, especially for those hoping for iPhone 4.0 multitasking miracles, Furbo.org tests show iPad is using the same 256MB of RAM as the iPhone 3GS. We were hoping for me — as in double. If true, there are other ways to handle the demands of multiple apps, but there’s no such thing as too much RAM when we’re still talking MBs…

Venture Beat claims a “very trusted” source has informed them that Apple’s PA Semi team might not have been behind the new iPad‘s Apple A4 chipset:

PA Semi didn’t do the A4. It was the existing VLSI team. Apple has made custom chips for years like the Northbridges for G4 and G5.

This information was appended to an article that focused on how great, and power-efficient, PA Semi’s chip design really was. So why wouldn’t Apple use them? Gizmodo speculates:

there likely isn’t a whole lot “custom” going in the A4′s actual design, which by all appearances is an ARM Cortex A9 wrapped up with a PowerVR graphics core and some other parts in a custom SoC. So, new question, if it’s true: What’s PA Semi, which Apple said would be working on chips for iPhones actually working on? A more customized chip would be interesting, since PA Semi’s true talent was in designing chips with ridiculous power efficiencies.

So, we won’t see PA Semi until… Apple A5?

According to Bright Side of the News, it turns out that newly spun Apple A4 system-on-a-chip that debuted alongside the iPad does indeed pack more punch than the Sammy in the iPhone 3GS:

A4 is a System-on-a-Chip, or SOC, that integrates the main processor [ARM Cortex-A9 MPCore i.e. Multi-Processing Core, identical to ones used in nVidia Tegra and Qualcomm Snapdragon] with graphics silicon [ARM Mali 50-Series GPU], and other functions like the memory controller on one piece of silicon – not unlike what Intel is trying to achieve with its future “Moorestown” Atom processor that debuted inside LG’s Smartphone

Cortex A9 indeed? But no PowerVR SGX like the iPhone. Engadget says this is also similar to the Tegra2 platform. So, it’s more of an Apple assemblage of ARM components rather than anything PA Semi unique, but is it a first step towards more customized silicon? Either way, we’d still love to see this baby powering the 4th gen iPhone and iPod touch.

Still no word on RAM though…

During ARM’s Q3 financial results announced today, 9to5Mac noticed this little gem:

including a license for ARM’s 2GHz implementation of a dual core Cortex-A9 processor.

We’ve heard about the Cortex A9 before. Purportedly, is 5x faster than an intel Atom, yet uses the same amount of power in a 60% smaller package.

Could this be for next year’s iPhone? For a mythical (maybe even second generation) iTablet? We don’t know, but 9to5mac speculates:

Apple is rumored to be an ARM licensee and that that they’ve reportedly split the PA Semi group up into two parts. One working on Smartphone chips the other working on tablet processors. It is now generally accepted that the Apple tablet will run a ARM Cortex processor. It will likely want a bit more horsepower than the ARM Cortex A8-class Samsung chip inside the iPhone 3GS.

Whether or not it’s Apple, the PA Semi group is working on something, even if it won’t be until next year that we get to see it. Anyone else care to speculate?

Apple Insider reports that Samsung has a 45 nanometer, 1GHz ARM processor, code-named “Hummingbird” on the horizon.

It uses the same Cortex A8 architecture as the current iPhone 3GS (which runs at a clocked-down 600MHz) but due to the smaller size, is said to not consumer any more power or generate any more heat than the current 833MHz generation.

Apple has made huge investments and agreed to large scale licenses of the ARM chip, even as they’re moving ahead with their own, in-Apple chipset initiatives.

So, even if Samsung ships this baby in time there’s still no telling if Apple will use it for a forth generation iPhone, likely to cycle around June 2010.

Still… Zoom. Zoom.

Following up on rumors of a $800 Apple netbook, MacBook, iTablet, etc. VentureBeat reports that Apple might also use the new platform to introduce their long-rumored custom system-on-a-chip.

This would be the result of Apple purchasing fabless chip design firm Palo Alto Semiconductor (PA Semi) and hiring Papermaster from IBM and graphics processor (GPU) gurus x2 from AMD/ATI (though whether or not it includes the ARM and PowerVR licenses for cores found in the iPhone and iPod touch, or beefier Intel chips found in the Mac line is uncertain).

While Steve Jobs said PA Semi was going to be used for iPods and iPhones, VentureBeat claims the team was actually split in two, half for iPod/iPhone and half for the tablet.

TUAW speculates that, given recent news of problems between Apple and Nvidia, who currently makes the Mac integrated chipsets, perhaps Apple will push the custom work into that line as well.

Either way, we’ve seen the huge benefit shared software technology has provided for the iPhone and Mac (Spotlight, QuickTime X to name but two), Apple going in-house with the chipsets could be just as beneficial…

MacRumors is reporting that Apple’s new iPhone 3GS, while indeed using Imagination Technologies’ PowerVR graphics core, may just have a little more under the hood than previously thought:

iPhone developers, however, have discovered that the iPhone 3GS has extension files named “IMGSGX535GLDriver” suggesting that the new iPhone uses the more powerful graphics processor intended for “high end” mobile devices. This may not be entirely conclusive evidence by itself but it is consistent with a report from a Anandtech commenter who claims to have heard directly from Apple engineers at WWDC that the iPhone 3GS does indeed use the SGX 535.

Zoom. Zoom.

In a related story, Apple has apparently raised their stakes in Imagination Technologies to 9.5% on the heels of Intel’s 16%.

CNET has an interesting post up detailing what we can expect in the next generation ARM processor. Just yesterday we took a look at the iPhone 3G’s ARM 11 vs. the new iPhone 3G S’ Cortex ARM8 and the difference was impressive — most impressive. Well, next year is promising a dual-core ARM Cortex A9…!

Icebike sent this in, wondering out loud: “Is it too soon to start speculating on 2010?” And the simple answer is “no, no it’s not!” It’s longstanding practice here at TiPb to wait a polite 1.372 seconds after a new iPhone model is introduced, and then begin with “So, next year–”

That spirit in mind, TiPb can’t help but wonder what this, combined with multi-core PowerVR GPU’s, wrapped up into custom system-on-chips by Papermaster, the PA Semi team, and all those new GPU gurus toiling away in Steve’s basement, means for a 2010 iPhone? (No, I won’t call it an iPhone HD — yet!)

At the very least, I think DC comics is going to have to invent us a faster Flash!

Anandtech gives their usual in-depth look at the processors inside Apple’s new iPhone 3G S. First the CPU, the new ARM Cortex A8 and the short of it is — if the iPhone 2G and 3G were old 486 PCs, the iPhone 3G S would be a Pentium:

As for the GPU, the PowerVR SGX — even if it’s clocked down to half-speed, it’s rendering geometry 3.5x faster with a fill rate 25% higher as well:

Their take away? Well, they say the iPhone 3G S packs a similar hardware punch to the new Palm Pre, but while webOS uses some of that power for 3rd party multitasking, Apple’s “highly optimized software stack” will bring the speed.

And that only scratches the surface. For the gritty details, check out the full article.

[Thanks to Damon for the tip!]

T-Mobile Netherlands (via Wired) has let slip the formerly elusive specs for the iPhone 3G S:

• 256MB of RAM
• 600Mhz CPU

Anandtech (via Macrumors) gives further info:

Although unannounced, the iPhone 3GS uses (again) a Samsung SoC but this time instead of the ARM11 + MBX-Lite combo it’s got a Cortex A8 and PowerVR SGX; just like the [Palm] Pre.

So add that to the fast PowerVR SGX graphics core, and — to quote Steve Jobs — it’s a screamer!

Update: Apple Insider has a great run down of the technology inside the chipsets.

Apple Insider reveals that:

Sources have now reported that Apple has detailed that Imagination’s PowerVR SGX is indeed the graphics processor used in the iPhone 3G S, and that it is “designed for OpenGL ES 2.0.” The new 2.0 specification of OpenGL for Embedded Systems eliminates most of the fixed-function rendering pipeline for a programmable approach to 3D rendering using shader programs.

So while we’re not yet getting that PA Semi + multicore ARM/PowerVT + OpenCL + Papermaker + ATI gurus system on a chip we’ve been fantasizing about this year… we’re still getting a clear focus on speed from Apple. And that’s a Good Thing.

Oh, and yeah, that’s totally the Kingdom Come Flash trouncing his golden age and silver age counterparts in the graphic above. /geek.

Something seriously smoking be going on round Apple way if the latest story from The Inquirer (via MacRumors) is to be believed:

We’ve just heard from sources deep inside 1 Infinite Loop in Cupertino, California that [Raja Koduri, AMD/ATI Chief Technology Officer, Graphics Product Group] is heading there.

So for those keeping score at home, this adds to:

• PA Semi lower-power PPC chipset designer: bought
• ARM cpu: licensed
• PowerVR GPU graphics core: licensed
• Mark Papermaster, IBM chip guru: hired
• Bob Drebin, AMD/ATI graphics guru: hired

Steve Jobs has said Apple is working on their own systems-on-chip for future iPhones and iPod touches. Looks like that work has got some serious hardware, and talent behind it.

Our only question is, what’s going to melt the universe first, the Hadron Collider, or whatever Apple’s got cooking up in their basement?

The Inquirer (via iLounge) is reporting that AMD (formerly ATI) Graphics Products Group CTO Bob Drebin has updated his LinkedIn page to show he’s found a new home — at Apple.

This is another in an increasingly long line of chip-related acquisitions, licensing deals, and staffing additions Apple has made in the chipset arena in the last year, including buying PA Semi, licensing ARM and PowerVR, and hiring Mark Papermaster.

Even though leaked specs for the next gen iPhone suggest previous iPhone chip-maker Infineon is still on board for now, it’s fairly clear Apple is looking to make changes further out on the product road map.

Our editor-in-chief, Dieter Bohn, is wondering what they think they know about chips that nobody else does, driving them to move this in house?

We’re guessing it combines Apple’s desire for control and hardware customization/differentiation. Why do you think, and more importantly, what do you think Apple is going to do with all this firepower under the iPhone (and iPod touch) hood?

Way back on Sept. 7 we linked to an item that conjectured Apple might be the secret licensee of PowerVR technology. Well, the conjecture is now confirmed according to MacRumors:

Apple is “subscribing for” 8,200,000 new shares of Imagination Technologies Group which means Apple will have an ownership interest of 3.6% in the company. The press release also reveals that Apple is a licensee of Imagination’s technology.

What does this mean for the iPhone? That Apple is likely Spinning Custom “PA Semi” ARM Chipset for Next Gen iPhone!

Apple Insider is reporting (via CNet) that Apple has hired away Mark Papermaster, IBM’s VP of Microprocessor Technology Development.

When Apple bought Palo Alto Semiconductor (PA Semi), and reportedly signed licensing agreements with ARM and PowerVR, we kinda sorta suspected Steve Jobs was getting serious about spinning his own custom systems-on-a-chip for the iPhone and the greater iPod platform.

Hey, if they can switch from Intel integrated to Nvidia chipsets to support their Core 2 Duos on the Macbook line, they can certainly role their own mobile brains, right?

IBM is suing on the grounds of a no-compete clause, which has historically been worthless in California (which is likely why IBM is suing in New York!)

TiPb, of course, doesn’t really care about no frivolous lawsuit. We just want to see what kind of “screaming” fast new iPhones we can has next year!

We love it when a plan comes together. What plan? How’bout Apple buying super low-power fabless chip design firm Palo Alto Semiconductor (PA Semi) back on April 23, which Steve Jobs later said would make “system-on-chips” for the iPhone and iPod? How about PowerVR graphics cores reaching a mega-licensing deal with an unnamed company? (Which might just rhyme with Snapple…) And how about now, a Mr. Wei-han Lien, formerly of PA Semi, updating his Linked[In] profile to read: “Senior Manager Chip CPU Architect at Apple”, and more specifically, “ARM CPU architecture team for iPhone”? (ARM having reportedly also reached a long term licensing deal with an unnamed company)

Put them all together, and what do we get? A scary hardcore look at what will drive the next (and/or next after next) iPhone v3. And according to Macrumors:

By developing its own ARM variant, Apple could create a processor that meets the specific needs of the iPhone and iPod, building support for functions such as the touch screen or scroll wheel into silicon and possibly savings on costs by reducing the number of processors needed in each device. In addition, Apple’ will be able to maintain tighter controls on who knows what about its future products by disposing of an outside chip supplier.

Wanna bet Steve calls them “screamers”? And Carmack claims PS2-class gaming?
