Apparently the A4 chip is an ARM system on a chip, integrating the CPU and GPU in the one package. Very interesting read indeed. It looks like Apple/PA-Semi designed the chip with technology that licensed from ARM.

So how long before we see an iPad running android.

If you want to use an Android Tablet, then you buy a Archos 7, Archos 9 or something like that. The HP slate also has a version that run Android. It's not that easy to come up with all the drivers that supports the iPad hardware and run on Android OS I guess.

Great link!
So it seems ARM did all the heavy lifting and PA Semi/Apple took all the other bits (GPU and some other stuff I guess) and slapped it all on a SoC. I'm surprised they went with ARMs GPU and not one from Imagination, who they've been pumping a lot of money into lately.

Meh, I'll wait for the A4 Quattro… :p

You guys read any of the comments associated with that article? Makes you realise just how nice a place MacTalk is to hang out online!

Steve Jobs said iPhone will have a A+ upgrade. Do I think the answer is more likely a yes

Everything that has been found about it is that it's at it's most basic form the same general stuff.

The advantage that Apple has with the A4 is that they have some of the best low power / high performance chip engineers - guys that have proven themselves to be the very best.

Some loose assumptions and speculation, based on that article and other info on the net.

- Apple's A4 CPU might be based on the ARM Cortex-A9 architecture (running at 1ghz). Apple A4 SOC unveiled - It's an ARM CPU and the GPU! (http://is.gd/7y8NF)
- Old news, but the iPhone 3GS uses an ARM Cortex A8-based CPU (running at 600mhz). AnandTech: The iPhone 3GS Hardware Exposed & Analyzed (http://is.gd/7y9E3)
- The Nexus One uses a Snapdragon CPU, which is based on architecture similar to ARM Cortex-A8 core (running at 1ghz). Snapdragon (processor) - Wikipedia (http://is.gd/7ya6K)
- The "4" portion of the A4 chip might mean "4 cores", because the ARM Cortex-A9 can support 4 cores. ARM Cortex-A9 MPCore - Wikipedia (http://is.gd/7yasx)

Could be pretty quick.

Nice round-up Marc!

Everything I've seen (from the product placement at the Grammy's to Steve on stage) has shown that this thing *flies*.

Stephen Fry was totally taken (http://www.stephenfry.com/2010/01/28/ipad-about/#more-1965) by it - he believes that once you play with and get hold of it you will forgive any missing parts that you believe there to be because it's just so dam quick.

Taking the speculation to ludicrous speed (http://www.youtube.com/watch?v=mk7VWcuVOf0): Maybe the multi core CPU will be handy because Apple are introducing multi-tasking in iPhone OS 4.0 and iPad OS 1.0.
