Will using open GL in android application reduce the system efficiency?

I have heard that a processor without graphics card will take a lots of time to produce a graphical entity,than one with graphics card. So is there anything like that if we use Open Gl in android application?? will my application 开发者_运维知识库become slow ??

Without a GPU/hardware accelerated video, the graphics would be calculated/drawn/rendered with the CPU (software rendering). This will definitely be slower than having a GPU, as GPUs are more suited at processing/displaying graphics like with OpenGL.
