I had actually noticed there were some applications that ran noticeably smoother in HC (on the TF101) than GB (on the SGS), thanks to GPU acceleration, even though the tablet has to push nearly 3 times as many pixels around the screen. A prime example is the Read It Later app, which maxes CPU usage on it’s jerky page scrolling, but the Instafetch app has buttery smooth transitions with minimal CPU usage, while displaying the same information. Note that many standard apps (such as GMail / HC Browser / GReader / G+) are already GPU accelerated. Also another reason why I choose LauncherPro on the SGS.
“Earlier this year, Android 3.0 launched with a new 2D rendering pipeline designed to support hardware acceleration on tablets. With this new pipeline, all drawing operations performed by the UI toolkit are carried out using the GPU. You’ll be happy to hear that Android 4.0, Ice Cream Sandwich, brings an improved version of the hardware-accelerated 2D rendering pipeline to phones, starting with Galaxy Nexus.”
