In this answer to a question about the performance of Jedi Fallen on Arqade, user nolonar gives an outstanding breakdown of how Nvidia names their cards and how that relates to performance.
Does AMD follow a similar naming scheme of Prefix, Series, Tier, Revision, and Suffix? Assuming AMD uses a predictable naming scheme how does that relate to performance of the card?
Yes AMD does have a naming scheme.
The first digit is the generation, currently the newest cards are the 7th generation.
The 2nd digit indicates what level the card is. A 9 is the highest performing card where as the 8 is middle of the road performance, and a 7 is low end.
They continue to get slower as the number decreases.
The 3rd digit is mostly unused, but sometimes they use a 5 to indicate it has slightly better performance than one without the 5. Usually it means a bit higher core speed and maybe a bit more memory.
I have never observed the 4th digit to be anything but 0.
In this generation the best cards are the 7900 and the 7900XTX (top of the line).
