You can color us ignorant here, but we sort of figured that after all those regulatory hoops AMD jumped through in the process of getting approval for its ATI acquisition, the DOJ would've wrapped up any antitrust reservations it might have before the $5.4 billion deal went down. But for whatever reason, the Justice Department picked late Thursday to slap AMD with a federal subpoena regarding an investigation into possible antitrust violations in the graphics card biz. As if this wasn't weird enough, we just got word that NVIDIA has been slapped with a similar subpoena, with just as little explanation as to why. Shares are down for each company, both of which hold about 25 percent of the graphics card market, with Intel managing the rest. Intel apparently hasn't received a subpoena yet, but a spokesman said he was checking with the company lawyers just to make sure. According to analyst Nicholas Aberle, "It's a bit of a headscratcher. I don't know exactly what the angle is from the DOJ." We're just as much in the dark, but we'll definitely be keeping an eye on the situation.
