Q1: How can I tell if the graphics cards in my systems will support
the new features of Core Image? One system has an ATI Radeon 9600
Pro, and the other an nVidia GeForce FX 5200.
On apple.com it claims the following cards are "GPU programmable":
ATI Mobility Radeon 9700
ATI Radeon 9600 XT, 9800 XT, X800 XT
nVidia GeForce FX Go 5200
nVidia GeForce FX 5200 Ultra
nVidia GeForce 6800 Ultra DDL, 6800 GT DDL
I'm guessing that my 9600 Pro is not a 9600 XT, and my FX 5200 is
not an FX Go 5200 or FX 5200 Ultra. Running "Cocoa Image Fun
House.app" for instance, I notice that it does nothing at all to
the images.
This is very odd. Core Image should render the effects regardless of
whether or not you have a programmable graphics card. If an
appropriate card is not there, the computer should use AltiVec and
other technologies to do the same rendering.
The rendering (most likely) won't be as fast... but it should still
happen.
Q2: Are the supported graphics cards available anywhere, or are
these special Mac-specific cards that I have to buy through Apple
channels? Is there a driver component as well?
The hardware should be available "anywhere" but there may be a driver
component. You would probably have to check with the card
manufacturer to find out.
