You might have seen a review of AMD's Radeon HD 8770M mobile GPU appear on the site and then vanish earlier this afternoon. We've had to take it offline after being notified at the last minute by AMD about errors in the information we received during our briefing. As it turns out, the parts we were sent were labeled incorrectly, and some of the information we were given was incorrect.
Since our benchmark data is still accurate but the article text needs revising, we're going to make the appropriate changes to the review before bringing it back online. We'll try to implement these fixes as soon as possible.
Update 6:25 PM: The amended review is now up.
