Because it is a better chip
Wishes ain't reality
Game emulators are a main gaming use on Android for me. The A7 cpu power destroys current Android used chips and the 810 next year will be the first challenge to that. The A8 though supposed to be 20% more powerful for CPU than the A7.
GPU though they are all getting closer to equal. CPU is the real area for improvement.
Will be an interesting battle!
Added: Side note- This device still does not have a lot of pre-launch buzz. My guess is a lot of folks that would have got the N4 already got G3's. Just a hunch. Most folks are light to medium users, so the G3 is fine in that regard. Contrast is not good, but your eyes adjust to it.
Really thinking we are seeing the end of the Samsung dominance for flagships. The pressure really goes up if LG releases the 805 version of the G3 this fall. Will likely be priced lower than the N4, so would hurt N4 sales even more.
Must admit the G3 with an 805 and better display tech would be very appealing. Catch is the display tech on the G3 805 is the same as current G3.
