iPad 3 performance
I have very heavy project (run good on pc, but slow on iPad2) and I think to upgrade to iPad3 to improve performance. How many difference in graphic performance there are between iPad2 and iPad3? Improve things?

This is a pretty darned broad question that I don't think anyone will be able to give you a straight answer for. Everything doesn't rely on the hardware alone, if anything, your code and what type of assets you use can play the biggest factor in mobile development. Not only that, but the powerVR chips used in iOS devices are tailored in a different way than other mobile platforms, so you have to take that into consideration as well.
My personal experience, is that (obviously) the iPad3 trumps the iPad2 pretty heavily, but it all comes down to a balancing game. If you're running a game that is heavy on effects, these may have to be scaled back to get higher resolution models in, and so on, and so on.
Here are some links that may help you out, they're not directly related to Unity but game development in general:

Having a thesis to finish and hoping to solve my problem, I decided to buy the iPad 3. I compiled the same application on both devices and I must say that the difference is remarkable. Obviously, the other major difference is the image quality. The thin lines and small text are displayed optimally. $$anonymous$$ine is just a personal observation, I have not done extensive testing and of course the considerations that apply to my application. Greetings.
It's going nowhere but up... with the market penetration that Apple has, any considerable changes they make on their iDevices considerably impacts the 'followers' of their design principles and overall popularity of their design choices as well. Take for example retina display... i$$anonymous$$acs and $$anonymous$$acBooks ( in the next iteration ) will come with extremely high resolution displays, and most all popular manufacturers are going to follow suit...
The thing is, this hasn't been done before because cost, technology available, and the manufacturing processes involved with said tech. With fabrication of processors nearing the 20n$$anonymous$$ mark and below, power consumption and processing capability for graphics are going to start getting insane, and to my opinion, to the uncomfortable level of reality. As of now, the mobile market is still kind of in a weird state, in being that it has the toppling potential to wipe out a lot of AAA title game studios (which has already happened and will continue to trend this way), but this won't happen until full adoption of hardcore players come to this arena. This is when you'll start seeing the iPad and like devices become the mainstream "console" that a lot of people have to carry around and hook up to their home entertainment systems, but this in my opinion is limited by the tech as I just stated. We're almost to that critical mass point though, in the next two years, the graphical prowess of mobile chips are going to make a giant shift ga$$anonymous$$g dollars.
Granted, there already was a huge shift in ga$$anonymous$$g dollars, but this is mainly due to social games. I'm talking mainly AAA titles that will require better tactile input such as a real controller, not a touch screen. I know this might be going on a tangent, but I thought I'd just spit out some babble since you used the word 'thesis' in your comment =p.
Thanks for the reply. I used the word theory because that's what I'm doing: my university thesis. An iPad application. However it was not my intention to advertise apple. I only had a problem and I tried to solve it. I do not understand the negative evaluation to my question ... I wrote something wrong?

I know this is an old post but from my current project I can tell you that iPad 3 under certain scenarios will actually perform worse than iPad 2. Although iPad 3 is running at 2048x1536, it is using more or less the same processor to push 4x the number of pixels to the screen. In my current project, iPad2 and iPad Air runs smooth but iPad3 is pretty jittery and cannot maintain even 30 fps.
