About speed of various GeForce cards

Please have a look at the attached screenshot.

Where’s an 8400 GS PCI there?
And where a GTX260?

The legend only tells about 8800.
Is a bad 8x card slower than a good 7x one?

7x does not support CUDA, is it is quite useless.
You may estimate&compare performance of any 8xxx are later cards by multiplying number of SP * shader domain clock.

Memory bandwidth (device to device) would be a better approximation of overall performance (though it usually is correlated with what you mentioned)

This big list of cards is sometimes handy for that.

Ok thanks guys. The big list is good, you can take out the GFLOPs directly.
