PHThe GPU is the Graphics Processing Unit. Its very much like the CPU, but instead of crunching numbers and taking care of tasks for the operating system and hardware, the GPU renders graphical information and puts it on the screen for you.

When GPU rendering was first added, it was very unreliable. Sometimes it would be slower than software rendering, and there were some kinds of GUIs that it just couldn't work with. For this reason, it was up to the app developer to test their app with GPU rendering, and set an option in the app's manifest (the same place that it declares its permissions) to enable GPU rendering for that app. The option was mainly to make it easier for developers to test the effect of GPU rendering on their app. This makes sense because:

Enabling this preference in developer options offloads task of rendering window components like buttons, text and complex 2d graphics calculations to GPU. This often results in much faster UI rendering including animations. On one side you will definitely achieve better frame rate (and hence smooth experience) throughout system, but you may end up using more battery. On certain devices, GPU consumes more power the CPU, hence you may observe 5-15% lower battery life with option enabled.
I would recommend having this option enabled on devices with weaker CPUs e.g. You should seldom need to enable this on dual-core 1.4ghz ARM CPU.
Offloading UI rendering to GPU has obvious benefits so that CPU can work on other important tasks like database IO, data manipulation, layout calculations and responding to other user inputs.
So pag naka on to magiging smooth but mabilis din madradrain yung android mo..
Naka on siya saaken kasi gusto ko smooth e.
So nasayo parin yan kung gagamitin mo and also ginagamit daw to ng mga developers to test their apps.
Kaya tinawag na developer option

- most users don't know or care about what GPU rendering is, and don't know whether it should be on or off for any given app; and
- the setting really needs to be per-app, not device-wide, because some apps just wouldn't work with GPU rendering turned on.
