A previously-unknown Samsung device has recently popped up in GL Benchmarking – it looks like we have a mystery on our hands. What do we know about the new device? It has an HD display (1280 x 720), runs Jelly Bean, has a max CPU frequency of 1600MHz and is dubbed the SGH-I317.

Okay, let us attempt to put the puzzle pieces together. The model number indicates that this is either an AT&T device or its meant for the Canadian market. If it's Canadian, we really can't tell from the number which carrier it is.

Taking a guess here, a variant of the Samsung Galaxy S3 or even the Note 2 comes to mind.

Let's take a look first at the Galaxy Note. The only problem here is that AT&T's original Note had a model number of SGH-I717, which doesn't seem to fall in line with this number. Does the Note 2 have to be listed as a higher number? Not necessarily, but it would make more sense if it did.

What about the Samsung Galaxy S3? While Samsung Galaxy S3 originally shipped with ICS, some markets are just now getting the device with Jelly Bean on board, so this is a possibility.

The truth of the matter is we just don't know. There have been no rumored higher-end devices that could fit with this model number, and so it's all just guesswork at this point. It could be nothing more than a variant of some existing device. Or it could be something brand new we've never heard of until now.

We'll keep an eye out and update on the mysterious Samsung SGH-I317 as soon as we know more.
