What we see is a 2.5 GHz Snapdragon 800-powered device with 1080p display, 2 GB of RAM, a 16 MP camera on the back, and 2 MP at the front. Temperature and humidity sensors are also conspicuously absent, and these are an integral part of Samsung's S Health app.
However, the source confirms that the benchmark is done on one of Samsung's engineering sample "mules", though, which are distributed for testing purposes to carriers and the like, prior to release.
These are usually stuffed in generic chassis, and the externals, as well as some internals, aren't the final deal, so it's too early to deduce anything from the benchmark system info and final results below. Another possibility is that this is a carrier version, but at least a 16 MP camera seems to be a done deal, if the AnTuTu leak holds water.
