Instead of Pitcairn cores it uses Tahiti LE cores. While not as good as the normal Tahiti cores based on the reviews they still hold their own against the real deal.
In some games it actually does better than the 7950, skyrim at under 1600P and wow at some resolutions.
Looks like it overclocks like a normal Tahiti too.
