Does anyone know if open-source video drivers like radeon use the
different GPU's in different cards differently? Maybe not and there
is just a flat identical acceleration for all of the radeon cards?

The GPUs are different, so yes, the driver needs to handle them differently.

So some perform better than others even with the open-source drivers?

For each card, there is only one open-source driver which will work
with its GPU (r300, r600 etc.).
Your only modern alternative is to use the official ATI drivers, but
it's difficult to maintain a current perspective on how they compare.
At least historically, fglrx has been better for 3D support, but
radeon has been more inclusive, supporting many older cards. radeon
has 3D support now, so that's a moot point. Feel free to try both and
post the results of the phoronix test suite for benchmarking.

Yes. Though the differences should not be as extreme as with the
Catalyst driver, since the open drivers don't use the GPU very effectively.
