There’s one significant difference between the two phones: the number of pixels on the screen.
The screen on the Optimus G is a little better than 720P HD at 1280×768, which is 983,040 total pixels. HTC’s Droid DNA has a 1080P HD screen (1920×1080) which equates to 2,073,600 pixels — yes, well over two million pixels!
Higher resolutions require significantly more calculations just to keep up. Compared to the Optimus G and doing the math, the Droid DNA has to figure out what more than twice as many pixels are supposed to display — and it has to repeat the task 60 time each second — or more.
Since the Droid DNA has more than double the amount of pixels, it stands to reason that it will take more than twice as many computations to render the display — and since the GPU and CPU specs are virtually identical, some might jump to the conclusion that the Droid DNA will be half as fast as the Optimus G.
You’re not going to care
Yes, technically the Droid DNA will be slower than the Optimus G, but that’s over-simplifying things a bit.
Remember when we talked about why the S4 Pro performs so well? Paired with its Adreno 320 GPU, the S4 Pro can handle not one, not two, but “multiple 1080P video streams – simultaneously”. The screen only counts for one of those “multiple” video streams. In other words: the S4 Pro has video processing power to spare.
Put simply: you’re not got to notice any slow down in performance due to the higher screen resolution.
Based purely on the numbers, the Droid DNA’s got the highest PPI I’ve ever encountered — it literally puts everyone else to shame. You’ll care about that. It will look amazing. You’ll be able to tell right away. Everyone who looks at your phone will be able to see the difference in the display right away. Although I haven’t held this device in my hands yet, I don’t see how HTC could ruin what has to be a gorgeous display.
As far as the raw numbers go, you’re really not going to care…
Unless the battery isn’t sized big enough to handle the power requirements of all the extra computation and lighting up the extra pixels…
We’ll have to wait for the full review to see whether or not HTC was able to mitigate the additional power consumption in what has the potential to be the highest-end smartphone we’ve ever seen.
