Yeah… HTC Rezound is really powered by Qualcomm Snapdragon S3 MSM8660 1.5 GHz CPU with Adreno 220 GPU. Just wondering can it have enough power to render 3D games smoothly on HD 720p (1280×720) display with old Adreno 220 GPU. Luckily, you still have quality Beats Audio technology. Just no nice and smooth 3D games on HTC Rezound only…

Verizon HTC Rezound
Finally, I found HTC Rezound benchmark based on per-production Verizon HTC Vigor. I keep following HTC Rezound specifications because it will be the first HTC smartphone with 4.3″ 720p HD resolution display. Having 720p HD (1280×720) on 4.3″ display == ~342 ppi pixel density. The display quality should be better than iPhone 4 / 4S retina display (~330 ppi pixel density) and Samsung Galaxy S II Super AMOLED Plus (~217 ppi pixel density).

Chainfire3D allows you to play Tegra, Snapdragon & PowerVR games on Samsung Galaxy S II with ARM Mali-400 MP GPU. However, by installing Chainfire3D itself does not allow you to play these games yet. Additional plugins are required to install before Chainfire3D can perform the task. Besides, you need to root Samsung Galaxy S2 first in order to use Chainfire3D. Not a simple task for beginner, so I created a step by step guide to install Chainfire3D on Samsung Galaxy S2.
