Under the current naming scheme you have the Radeon HD 7970, whereas under the new naming scheme this card would have been named something like "Radeon R9 770 x"
An example of this new nomenclature could be, say, Radeon R9 280 X, where "9" denotes the high-end market segment, currently held by Radeon HD 7900 series, "2" indicating generation, and "80" denoting variant. "XT" (full-spec) chips could get the "80" marking, and "Pro" (partial-spec) chips could get the "60" or "70" marking, but it isn't fixed, and could even be "50" and "40" for lower-end parts. At this point, we can't even speculate what the "i" (special feature) could denote. For mobile parts, the letter "M" could be prefixed to the "xz" component of the model number (example: Radeon R9 M380 X).
