    Screen Refresh rate on S1 or S2 compared to the iPhone

    Hey,

    has anyone notice a refresh rate difference of a 9530 and an iPhone. The iPhone flick scrolling looks better than on my storm (9530 5.0.0.230). Anyone have any thoughts to why or if maybe the S2 refresh rate is higher. That really improves the look when flick scrolling. I'm happy with my storm. But I was doing a side by side comparison and notice how fast the the refresh rate is on the iPhone.

    Just throwing that out there.

    rocks! :hail:

    We all need to remember as well that the iPhone to date is 3rd generation.
    Having said that...95xx is first gen and is just now produced as a second generation device.

    Just my obsevations...

    Another factor involved could be the processor. The Storm, well all VZW phones are limited to the Qualcomm chipset which is significantly less powerful than the ones available to GSM phones.

    Not to mention the iPhone has its chip's graphics processor unlocked unlike our Storm's. So calculations can be dumped to the graphics processor for things like the flick scrolling and it can do the calculations faster, thereby possibly making the scrolling look smoother than when the entire process is being handled by the Storm's processor.

    Just something I thought I heard once when people we discussing how the graphics are locked down on the Storm.

    Actually, the MSM7600 used inside the Storm is considered to be almost as powerful (if not more powerful) than the chipset in the iPhone up to and including the 3G. The chipset also has OpenGL capabilities on par with the iPhone. The difference is the GUI on an iPhone is fully hardware accelerated; but not on the Storm. It's much easier to use HW acceleration on a UNIX-based OS like the iPhone uses than a Java-based OS like a BlackBerry device uses. Thus the Storm lacks any significant HW acceleration even though the HW is capable.

    Thats what I was wondering but I haven't seen any side by side comparison

    I have never seen it explained that way. Thanks Dave, that helped me understand why the graphics hardware was never used
