The comment states that the iPad is upscaling the iPhone 3GS graphics on the iPad, rather than just using the higher resolution iPhone 4 retina graphics at near full resolution.
I'm 90% sure that this is the case. I think that the main reason why Apple did this is because the iPhone 4 has 512 MB RAM, and the iPad 1 only has 256 MB(iPad 2 has 512). That could make performance with the higher resolution graphics an issue for the iPad.
- illumin8 16y agoI can verify this is the case. I have Final Fantasy III on iPad, which is a native Retina display app for iPhone 4, and it only displays with iPhone 3GS graphics in pixel doubled mode. This is unfortunate, and I think you're right. The iPhone 4 does have better graphics hardware than the iPad 1. It would be interesting to see if iPad 2 could overcome this limitation. Judging by the video I saw of an iPad 2 outputing 1080P to HDMI at 60 frames per second running Real Racing 2 HD, I would say that the iPad 2 has the graphics hardware to handle actually scaling a native iPhone 4 retina display app to it's own resolution.
