Truth to be told, AMD Radeon HD 7000 GPU series have actually arrived into mobile space just a short while ago via Radeon HD 7600M, 7500M and 7400M GPUs. However, these GPUs were actually based on previous generation 6000M series' Turks and Caicos GPUs while by then, the HD 7000 series for desktop have begun to offer new performance and enthusiast-level GPUs based on the new 28nm Graphics Core Next (GCN) architecture. The wait for GCN-based Radeon HD GPUs for mobile ends today though as AMD have officially unveiled the new Radeon HD 7700M, 7800M and 7900M GPU series.
