[FONT=Arial, Helvetica, Verdana, sans-serif]HUH? Come again? [/FONT] The S4 has a Quad-core 1.9 GHz Qualcomm OR the 1.6 GHz Octa-core ( One is an international device the other is not, example: Verizon version does not have the Octacore. ) The S4 runs Touchwiz ontop of Android, which is notorious for causing lag while navigating through the device menus. People get too wrapped up in numbers...a higher number doesn't always translate into better performance, look at the iPhone 5 (A6 1.3 GHz 1GB Ram), I don't like Apple's policies of locking everything down or how doing anything on the iPhone costs at least .99 cents, but I've owned an iPhone 5 and the Galaxy S3 with better specs on paper than the iPhone 5 did not offer me a better experience...for what I do, Android suits me best, but if I had to choose between an iPhone 5 or a Galaxy S3 I'd choose the iPhone and hope I could trade it for a Droid DNA, that's another story... The Droid Ultra has a Motorola X8 processor....it's a Qualcomm Snapdragon S4Pro family processor (1.7GHz Dual-Core Krait CPU, Quad-Core Adreno 320 GPU), a natural language processor and a contextual computing processor. 4 graphics processor cores 2 application processor cores 2 low-power cores—runs when you're not using the device to save battery and serves as a wake up for the rest of the processor when you want to actively use the device.
