I believe its Ruby but I could be wrong. I assume you are referring to the one that appears on reference sample graphics card made by ATI and not an ATI card made by another manufacturer, in which case, they probably have no name

Currently, it is popular belief that an nVidia card would be more powerful than its ATi counterpart.
the Intel is integrated into the motherboard and the radeon is separate is the visual difference....the latest integrated gpu's are still weaker than cards from 2001 from companys like ati or nvidia......
for consumer graphics cards, the hd3850 from ATI is the most powerful. the 2600xt is also a close match for workstation cards, quadro fx4000 from nvidia
yes you can, but for now only with older graphic cards, for example I have an ati hd3870 and it can't run it
