What is this rattling about 920 being better than 640XL? Have you even read specs? 640XL has clear black screen, has Carl Zeiss optics, and has HD screen. Gaming? Dual core 920? Really? It seems that 920 owners aren't ready to accept that their phone is outdated. By the way, Nokia 5800 XpressMusic also has Carl Zeiss. So why they even bothered making new phones!?!! Get serious, please.
Do you know about the specs?
The 920 has a CBD, Carl Zeiss optics AND OIS, and an HD screen, etc. etc.
Gaming? Dual core 920? Yes, I believe the 820/920's graphics chops is stronger than that of the XL, 830, 735... Processor cores don't tell the whole story.
And benchmarkwise, the Snapdragon S4 in the 820, 920 is about on par with the Snapdragon 400 in the 830 and other phones, including the 640.
Yes, its outdated, but remember that the 640 XL is a midrange phone and doesn't represent the best performance in a current phone whereas the 920 was higher up the ladder when it came out.
Well the Lumia 435 is newer than the 920, must be better right?
The ClearBlack tech is identical in the 920 and 640 XL
Not exactly, I'm sure its different in that its probably seen improvements, but then again, its probably also seen cost cutting too.
