That compares the new iPhone 5 to the HTC One X. The OP was asking about the iPhone 4S. While the iphone 5 has pretty much caught up in processing power, the iPhone 4S is way behind the One X. The screen resolution on the 4S is higher, but that is only because the screen is much smaller.
I am considering the One X and have checked it out in the store. The only reason I have not bought is because I want to have a look at the soon to come out new One X and the Samsung Note 2. Yes, I like the One X's screen a lot better than the Note 1, but I would like to have a pen.
