Just wanted to know what is the difference between 5S and 6 retina displays.

Both are at 326 ppi, then how is 5S Retina & 6 Retina HD ?

Thanks,

Just terms. They're probably calling it Retina HD because the screen is bigger. I mean it was HD resolution in the 5s and below but on such a tiny screen.

Just marketing terms, that's all.

Nope...the iPhone 5S was 1136x640, so 640p. HD is 720p or above. iPhone 6 has a 750p screen and the 6 plus has a 1080p screen. Basically, no HD on 5S and HD on 6/6 plus. Hence, retina HD.

Apples use of the term HD is a bit arbitrary. In the end it doesn't mean anything. It means whatever the Apple Marketing department wants it to mean at any particular time.

Wasn't pixel density the real difference between screen resolutions, 6 has larger screen so 720p+ will fit in; This was the gimmick they had come up when mini was first launched, same screen as iPad but smaller in size so better pixel density.

another thing, i can watch 720p videos on 5S and it fits pretty well for that matter.

You can watch 720p videos on the 5S, but it is downscaled to fit in the lower resolution, so you lose a bit of detail. Pixel density has to do with screen resolution in relation to the screen size. A big screen with low resolution has a low pixel density, while a tiny screen with a high resolution has a high pixel density.
