Samsung tips off T-Mobile Galaxy S II CPU choice
Samsung in a response on Twitter gave an answer as to the mystery of the processor in the T-Mobile Galaxy S II. A social media spokesperson said it was the 1.5GHz Snapdragon APQ8060, the same processor as in the TouchPad 4G. Every other Galaxy S II version so far uses Samsung's own 1.2GHz Exynos chip.
It's still not clear why the T-Mobile version will have needed one of Qualcomm's chips, although it may have to do with network choices. T-Mobile's need for the 1,700MHz band on its HSPA+ 3G, which might go to a rare 42Mbps, could have pushed Samsung to change processors to get the frequency support it needed.
When it ships, which is expected in mid-to-late October, the T-Mobile edition may not be as fast in raw performance as the AT&T and Sprint versions but could make up for this with faster data and a larger 4.5-inch screen. Every model has an eight-megapixel rear camera and a two-megapixel front camera.
