We have to wait for the official specifications until March 14 in the Samsung Unpack 2013 event in New York.
The rumored specifications of Galaxy S4 have two versions on processor (chip). One version says Samsung ‘s own Exynos 5 Octa (5450) will be used; while other one says Samsung may use Qualcomm Snapdragon 600.
The logic question is which one is better, or what the differences are. In the Galaxy S4 rumored specifications, I told you guys my bet is on Exynos 5 Octa. I will tell you my reasoning later in this post.

Both Exynos 5 Octa and Snapdragon 600 were announced this year. Most high-end smartphones and tablet will use one of them this year. Snapdragon 600 already got customers lining up: HTC (HTC One) , ASUS (Padafone Infinity), LG (Optimus G Pro) and ZTE (Grand Memo).
Both processors are based on ARM Cortex A-15, and share the identical instruction set (ARM v7). This is the latest version of ARM technology in the market.
Bother are fabricated with 28nm technology, which means more transistors in the same area compared with the 32nm (for example, Exynos 4 Quad used in Galaxy S3, Galaxy Note 2, Galaxy Note 10.1, and Exynos 5 Dual used in Google Nexus 10) or 45nm ( for example, Exynos 4 Dual used in Galaxy S2, Galaxy Note; Snapdragon S4 Play) technology. For Samsung, it is a big leap because it is it’s first 28nm processor. While Qualcomm have used 28nm technology since last year. Both Snapdragon S4 Plus (for example used in Nokia Lumia 520, 620, 720, BlackBerry Z10, HTC One X… Read the rest
