The GSIII runs a Samsung Exynos 4 quad-core processor outside of North America, clocked at 1.4 GHz, and a Snapdragon S4 dual core clocked at 1.5 GHz in the U.S. Apple's iPhone 5 runs an A6 dual core, bench-tested by third parties at 1.02 GHz. At 4.99-in. or 5-in., depending on the report, the GS4's display would be a tiny bit bigger than the GSIII at 4.8 inches but noticeably bigger than the 4-in. iPhone 5.
Milanesi called the display and resolution increases "incremental improvements that are important but not necessarily things that will sway consumer purchases."
Whatever hardware and software improvements are in store for the GS4, Samsung's event promises to be a marketing spectacle to draw attention to the smartphone. The event will be held at Radio City Music Hall, and Samsung is promising a live video stream over YouTube starting at 7 p.m. ET.
