The power of
ipod touch.
Evolution of ipod touch in the history of Apple computer and how apple has managed to sell so many ipods to other fellow human beings over these years.
Evolution and difference between the different ipod touch.
basically ,
iPod Touch 2 = iPhone 3G minus the camera, ear piece, and cellular radio.
Battery
- 3RD GEN
- 30hrs audio, 6hrs video
- 4TH GEN
- 40hrs audio, 7hrs video
It may not seem like a big change here, but think about it for a moment and a whole 10 hours of audio playback or an extra 60 minutes of video time is actually pretty significant. If you're using the iPod touch both as a gaming device, a media player and, as we'll see, a camera as well, it's an excellent addition.
CPU
- 3RD GEN
- 833MHz ARM A8
- 4TH GEN
- Apple A4 Chip
The upgrade to the Apple A4 system-on-a-chip solution on the iPod touch is the first big clue as to the core of what this media player refresh is all about. The CPU portion is another ARM A8 that should make it up to 1GHz clock speed, provided it's not been limited, of course. On its own it might not make all the difference in the world but considering the 3rd gen is underclocked to 600MHz, it's a bigger step than it looks.
Storage
- 3RD GEN
- 8GB/32GB/64GB
- 4TH GEN
- 8GB/32GB/64GB
Storage-wise, you're looking at the same creature. Both line-ups are available in the three sizes from 8-64GB, depending on how much money you have to burn. Given both a thinner chassis and the fact that the catalogue-sized iPod classic is still out there, it's really of no surprise that it wasn't bumped up.
Memory
- 3RD GEN
- 256MB
- 4TH GEN
- 512MB?
Apple has never been one for talking RAM specs, so we'll have to have a guess here until the teardowns hit the web. However, given that the 4th gen touch has got the A4 chip and was seen running some seriously impressive stuff at the keynote, we're willing to bet there's the same 512MB payload as you'd find in the iPhone 4.
Display
- 3RD GEN
- 320x480, 3.5” LCD
- 4TH GEN
- 960x640px, LED backlit
Possibly the most important upgrade between the the two models is the addition of the Retina Display as seen first, once again, on the iPhone 4. We know that the jump from 163ppi to 326ppi is pretty damn astonishing and it's the kind of category that's going to make all the difference if you're a heavy video user. Throw in the lower power drain and the IPS for a better viewing angle and it becomes the place where the 3rd gen owners will turn green with envy if they don't make the switch.
Connectivity
- 3RD GEN
- Wi-Fi b/g, USB 2.0, Bluetooth
- 4TH GEN
- Wi-Fi b/g/n, USB 2.0, Bluetooth
Not a lot of difference at first glance here but there is one letter that's a welcome addition. Yes, the iPod touch 4th generation model now has the further reaching and faster n-wireless standard. Very nice for a bit of browsing at home - unless you already have an iPad that is.
Graphics
- 3RD GEN
- PowerVR SGX 535
- 4TH GEN
- PowerVR SGX 535
Both generations have the same GPU inside, so you'll get decent gaming power on either the old or new model - a sigh of relief for those looking to keep up with the apps on the 3rd gen. One could argue that the integration of the graphics unit on the Apple A4 in the 4th gen is going to be more efficient and a little tighter but, essentially, you'll get a similar performance.
Form
- 3RD GEN
- 110 x 61 x 8.4mm, 115g
- 4TH GEN
- 110 x 59 x 7.2mm, 101g
It's become a matter of shaving slivers of metal off this thing each and every time now, largely because it's really thin already. This time the 4th gen is even thinner, of course. The bezel has been cut down on the width as well, but the big stat is probably the drop in weight. It's not drastic but it makes the 3rd gen look a little out of shape
Imaging
- 3RD GEN
- Nothing
- 4TH GEN
- Front & rear facing camera
Notmuch you can say here in the defence of not upgrading to the 4th gen iPod touch. Two cameras - one to take pictures with and one to FaceTime video call over Wi-Fi with - or, er, none.The rear facing camera is not much of a stills operator though. While you can use it record a very impressive 720p HD video at 30fps, the stills only come in at 960x640 which is equivalent to 0.6 megapixels. You're probably best off extracting the shots from video in post production. The front facing glasswear is up to VGA levels for both FaceTime chats and single snaps.
