The LG Optimus G2 may not have been officially launched, but there is already plenty of information about it available, thanks to a combination of internal announcements and reliable leaks. It is likely to be one of the most powerful LG mobile phones ever released, with the Snapdragon 800 processor giving it a reported 2.3GHz clock speed that should be enough to breeze through even the toughest challenges.

Recent reports and leaked images suggest that it will also boast a 5.2 inch touchscreen display with a full HD 1080p resolution, making it the equal of other industry front-runners like the Samsung Galaxy S4.

So how does the Optimus G2 stack up when compared with last year’s Optimus G and could LG’s new flagship device become the next in the long line of Google Nexus smartphones to undergo a brand revision at the hands of the Android creator?

LG Optimus G2 vs Optimus G

In the display department the G2 will be slightly bigger than the Optimus G, with its 5.2 inch panel marginally outdoing the 4.7 inch screen of last year’s high flier.

Arguably the real difference between the two phones will be apparent as a result of display resolution, not size.

The 720p screen of the Optimus G will be far less clear and crisp than the 1080p screen of its successor, with pixel density on the new device being particularly impressive.

Internal power will also be a defining factor, since although the Optimus G has a quad core chip like its successor, it will not have the same clock speed or efficiencies. This means performance should be enhanced on the upcoming LG Optimus G2, which makes sense given the generational shift that it is intended to introduce.

Whether or not Google will select the G2 to become a Nexus range phone is less certain, although it certainly has the right kind of credentials to take over this position. A 13 megapixel camera on the rear will match its predecessor. What makes it stand apart is the G2’s superfast processor will even endow it with the capability to record video at 4K resolutions. For the uninitiated, 4K is essentially twice the resolution of 1080p and a number of compatible TVs are going to start hitting the market this year, making it an emerging trend in consumer electronics that is worth watching.

All eyes will be on the IFA even in Berlin this year, since this is the anticipated venue for the launch of the LG Optimus G2. The Sony IFA 2013 show should also be interesting and even Samsung is likely to be showcasing a few new phones there, so LG will not be alone in debuting a new mobile device with high end hardware on board.
