In another demonstration of silicon health AMD was showing working 28nm mobile GPU silicon running Dirt 3. It's too early to talk about performance or specifications, but AMD is still committed to a Q4 release for its 28nm GPU lineup.

Seems no point going back from vliw4 after all that work trying to justify the change from vliw4+1, at least too soon for thatJPForums - Thursday, September 15, 2011 - link
The 7900 series is GCN.The rest of the 7000 series is the original VLIW4.
Take a look at the number of cores and the number of clusters in the upcoming 7900 series. The GCN architecture is a 4 instruction width architecture and is likely an evolution of their previous VLIW4 architecture for handling more compute oriented tasks.
Trinity was originally supposed to be bulldozer+VLIW4(original).
However with the apparent changes to the pile driver core (relative to bulldozer), some have speculated that AMD will put the new GCN cores into Trinity instead of the original VLIW4 cores.
I would expect to see the original VLIW4 architecture in Trinity given the timing and the probability that new GCN architecture takes up (marginally?) more space per core. It's quite possible that AMD will create a divergence between the performance and value oriented chips, similar to nVidia, where GCN derivatives are only used on their highest end models (x9xx series) and non-compute oriented VLIW4 derivatives are used for lower end. This, of course, would depend on how expensive the compute oriented changes are in regards to area and power. Eventually, AMD may decide that the cost of the compute oriented changes must be payed to further their CPU/GPU merger ambitions. For now, though, the current VLIW4 should provide more that enough compute capability for their goals.

Looks like they are running out of numbers for the Radeons, they already have 7000 series (was that first or second gen radeons?) Maybe its time to revert back to 3 numbers like Geforce LOL.Arnulf - Thursday, September 15, 2011 - link
7000 was first generation ATI Radeon. They used XY00 model numbers back then and they are using XYZ0 now so at least there won't be as much confusion as there would have been had they used identical numbering scheme.Targon - Thursday, September 15, 2011 - link
The current Radeons have a designation of Radeon HD, even if the HD is left out most of the time these days. As long as they don't use something like Radeon 2-970 for the next loop around, it shouldn't be too bad.Filiprino - Thursday, September 15, 2011 - link
We all want green products to eat healthy everyday. Just release Bulldozer and let the vegetation grow in the new and wonderful field.Radeon 7900 series now! Bulldozer? Too!
