Fast forward to present time and a source for Android and Me is saying that Samsung is going to release some handsets early next year that will blow away the Samsung GALAXY Nexus in every conceivable way. That would infer that the new models will have a quad-core CPU at the heart of the phones. If the Samsung Galaxy S III is introduced at the 2012 MWC in Barcelona as the 4Chan poster expects, we could be looking at the Samsung Exynos 4412, a 32nm quad-core product with speeds as high as 1.5GHz using ARM Cortex-A9 cores. The Korean manufacturer is said to be testing the processor and it recently appeared in the Linux Kernel archives.
As for a GPU for the handset, the Mali-T604 was a suggestion made by Android and Me which pointed out that it runs 5 times faster than previous Mali graphics processors. Using a tri-pipe architecture, the Mali-T604 was originally introduced by ARM in 2010 and Samsung became the first partner with access to it, although it has never been used.
We are still a few months away from the MWC in February 2012, so until Samsung takes the wraps off the Samsung Galaxy S III, it's all just a guessing game, albeit one that is fun to play.
