Apple's new iPad 3 features a modified version of the company's standard A5 processor, A5X, which has a larger floor plan to include quad-core graphics, according to an analysis performed by UBM TechInsights, one of our sister organizations.
The A5X measures roughly 163 square millimeters, compared to about 120 square millimeters for the A5. Both use identical ARM processor cores, but the A5X adds four PowerVR SGX543MP4 graphics cores, which are paired in groups of two and then symmetrically opposed to each other on the floor plan. Both chips feature two application processor cores and operate at 1GHz, but the A5X includes more DDR interfaces and more architecture added for the handling of quad-core GPU, according to the teardown analysis.

Seeing the apparent ease with which UBM TechInsights tears it down, it's a wonder to me that Apple is so resistant in their interviews. It's difficult to get through an Apple interview without bumping into a "proprietary concern." Yet, it appears from this teardown that reverse engineering of the hardware must be commonplace.
The iPad 3 is beautiful the same way the iPad two is, Apple should stop releasing new models with little improvements and wait more time to get something more interesting and technologically advanced, I think this is only a marketing strategy and not really an amazing new product anymore. Anyway the slides are very nice thanks!
I think Apple is the greedy giant. I don't support companies like these. I make my own desktops from mismatched parts from starter companies (one of the first to get GSkill ram cards at 800MHz) pay for OEM Windows and put my own sticker or logo on my computer, generally 20% cheaper too. I don't do it for the cost I do it for the pleasure of it. However apple does not only sell hardware, they sell art as well. There will come a day when I will select form over function. I have already succumbed to a galaxy G2X. Maybe one day i will own an Apple iPad or iPhone.
Right Aldo, Apple should stop releasing new models just like the auto makers should stop releasing new models with little improvements each year. I'm sure it's only a marketing strategy to get you to buy the same old thing with minor tweaks. We only want revolutionary changes. Evolutionary changes are such a bore. ;-)
Simplicity of design? Well, it looks almost like a cell phone motherboard plugged into an overgrown display and battery. Doing it that way does make a lot of sense. It also permits multiple sourced displays to supply an existing model production run.
As miniaturization moves along its path the PC board will continue to get less complicated as more and more of the motherboard moves inside the IC packaging. If you can manage the heat and the power rail current you want to shrink the length of the interconnects to help speed up the device and reduce signal cross talk (noise).
The tablet computer will probably trend towards cheap disposable general purpose multi-media computers for all. When the device ends up costing a small fraction of the investment in software applications, how will that affect the giant software firms or should I say firm, the MS elephant in the room? Will they opt to embed all of their apps in their own hardware making it difficult if not impossible to load and run someone elses cheaper apps? Deja Vu? Or will the world of 3rd party cheapware/shareware blossom again, like cell phone apps have? And where does cloud computing fit into this model?
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
