AMD announce GCN 2.0 graphics! (HD 8000 series) But don’t get too excited just yet…

[Soleron]

This is just a rebrand of existing 7000M high-end parts. No new technology. Most of the current 7000M series were rebranded 6000M parts.

The real next-gen doesn't come until later in the year, and even then it's still 28nm. Don't expect significant perf/watt or perf/$ changes until 20nm in 2014.
