Apple iPad confirmed

Tegra is a single chip, CPU/GPU/HD decoder.

that equates to smaller, faster, cheaper and uses less power.

based on Apple's other battery life estimates, a iPad is likely to have an everyday battery life of 5 hours.
 
Apple's battery life estimates are usually totally accurate.
 
Same to you. So far it's been accurate with my iPhone, iPod & Macbook so there.

The A4 competes with Tegra, battery life has increased because of the A4 chip.
 
True, so far the battery estimates (as stated on Apple's website) has never lived up to reality for my dozen or so clients using Apple products. The running estimates on the devices themselves are usually accurate though.

Its only only Apple, it nearly all manufacturer

Their excuse is that you must use it more than the average. On average their product must not be used much then

What's so great about Tegra? This already has a VERY fast ARM based CPU, as well as a decent GPU, with 10 hours battery life & 1 month standby.

The thing is that it's NOT a decent GPU. This thing can hardware accelerate only very specific H.264 and Mpeg4 profiles. If you have an atypical file or a higher spec or profile eg with GMC or QPel - it won't run. It specifically works with files which are sold by iTunes. That's what sucks when a hardware vendor is also the content provider - this case Apple. There is an incentive to lock the formats to specific ones traded by the store. Want to load your own? Sure, but convert them first. That is, I'd love this thing to be able to play more advanced profiles with open container formats including subtitle streams and dual or tripple audio (soundtrack choice) but it won't do it, prolly.

Most speculation has the A4 as a dual-core Arm Cortex A-9, which will be the same chip as in Tegra. My main point was the extra graphics power Tegra will bring, since it is designed to support 1080p (H.264/VC-1/MPEG-4), and it supports flash, at no apparent hit to power consumption. Obviously we will have to wait and see whether this is true.

Well, even Intel GMA 500 supports full 1080p in H264 and VC1 in h/w. That started shipping a year ago.

To be fair, Apple battery lives usually live up to expectation.

Panasonic does have a 'long run' battery though and can power i5 2.55GHz CPU for 16h max.

GMA 500 isn't (part of) a SoC, and it is x86 not ARM based. Atom + GMA500 has a TDP of <5w. Tegra has a TDP of 500mw (supposedly).

Two completely different implementations.
 
I'm sure the hardware is capable of decoding quite a few other codecs, Apple just doesn't enable it.

And Apple has always had accurate battery life claims in all reviews I've read. This is the one aspect I respect them for, anyway, we shall see when it's released.

I didn't say it was ARM based. It's an older chipset which can decode 1080p h.264 in h/w with no CPU hit.

Not at all. Both are aimed at ultra portables.

With highly optimised low wattage processors and chipsets the limitation is usually h/w based. This thing was designed for this purpose AND to have 10hr battery life.

lol I meant that it's two different implementations of graphics processing technology, if you couldn't figure out the implied rest of the sentence. SoC is quite different to having a separate chipset handle GPU processing. The new Atom n450, which has integrated graphics (and memory controller) on chip cannot do 1080p. At least not on its own.

There is some overlap between Tegra and Atom, but tbh Atom's design makes it useful only because of x86 compatibility. I don't see much use for it in embedded systems, simply because the power draw is an order of magnitude inferior to ARM based systems. I can only see them really competing at the tablet level, below that (smartbooks, ereaders, smaller embedded systems, TV boxes, etc) Tegra and Snapdragon will fight it out, while above that (netbooks, larger embedded systems, HTPCs, etc) it will be Atom and Nano (someone please make a netbook with the new VIA DX10.1 chipset!).
 
I think Apple needs to launch the iCon. First they con us into buying their over priced product with very little features, then every year after that, they con us into buying the same product because they added a new feature which was already in the first protype but removed in order to force us to buy the product sixteen times.

Oh, and this was posted today on twitter... to classic... Apple Evolution: http://twitpic.com/1054lj
 
It sure seems innovation fled the likes of Microsoft and is now roosting in places such as Apple - trust iPad will be a huge financial spinner for Apple to enable them coming up with more great ideas at acceptable prices.
