From reading various forums, it seems to me that some people call HD7xxx series Tahiti while some other call it GCN ???

7XXX series come in two chip flavors: Tahiti (7870 LE, 7950/70/90) and Pitcairn (7870/50, 7770)

What's GCN then ??

"Graphics Core Next (GCN) Architecture is a radically new approach to the design of a consumer GPU.

Most importantly, it is the world's first 28nm GPU architecture, which enables AMD to fit up to 4.3 billion transistors-the most basic building blocks of a GPU-into approximately the same space once needed to fit 2.6 billion. Increasing transistor density by greater than 60% is more than just a feat of engineering-it's responsible for the world's most powerful and advanced GPU.1"


Just a term they use for their 28nm GPU architecture.

They are both CGN, so nothing to be concerned with
