I've tested viewfinder frame rate on 6600 and 6670. Result of 6600 is quite reasonable, 25fps at 160x120, 15fps at 320x240.

Interesting, I was only getting 15 fps from 6600. Which format were you using ? EFormatYUV420Planar ?

That's not impossible as the CPU of the 6670 seems a lot more faster than the one of the 6600.....

I have no idea, I was just speculating on what might cause the difference you're reporting.

The camera in the 6670 has much higher resolution than the 6600. Depending on where the pictures are scaled down to the resolutions you specify, that might affect the throughput.

Do you mean that 6670 uses software for scaling instead of a image coprocessor?
