Update: July 15, 11:30 a.m.: AMD CEO Dr. Lisa Su confirmed that Frank Azor, co-founder of Alienware, has joined the company. In a tweet, she welcomed him as the "chief architect of gaming solutions."
According to Wccftech, he may be leaving to join AMD as Chief Gaming Officer reporting to Sandeep Chennakeshu, executive vice president of gaming and graphics.
A spokesperson for AMD declined to comment, as "AMD does not comment on rumors or speculation."
"I’m so proud of what we’ve built together. Our gaming and premium consumer businesses are outperforming the market and are a huge priority for Dell," he wrote. "But the builder and creator in me is ready for the next challenge. It will be very hard to leave this incredible team."
He also tweeted the news, suggesting he is staying in gaming.
Sources tell me that Dell is not looking to replace him immediately, but will eventually backfill his position. The company will be looking internally first, and that key Alienware employees don't intend on leaving en masse.
We'll update this story if and when we get more information.
