We already know the Galaxy S4 is going to be a blockbuster device, packed with the latest and greatest internals and the fastest processor Samsung has ever created. But while many of the specs have been rumored up until this point, a new document leaked today could shed light on what the phone may end up looking like.

A leaked PDF from the South Korean financial services company Mirae Asset Group confirms our suspicions. According to the PDF, the Samsung Galaxy S4 will feature a 5-inch 1920x1080p display, Android 4.2 and 2GB of RAM. However, there is one crucial difference between rumor and reality: it seems the Galaxy S4 will feature not the Exynos 5410 processor we saw at CES, but rather an Exynos 5440 quad-core Cortex A15 processor.

Sure, this isn't the rumored 8-core processor, but it is a Cortex A15, up from the Cortex 9 inside the Galaxy S3. And remember, more cores don't necessarily add up to better performance. Just to give an example, the Snapdragon S4 processor outperformed the Tegra 3, even with one fewer core.

Of course, this is all just a rumor at this point, even if the source may have a close financial partnership with Samsung. Sprinkle a few dozen grains of salt before consuming this one.
