The terms of the transaction was not disclosed. A Dell spokesman only mentionned that the acquisition was financially immaterial to Dell.
Privately held Alienware, based in Miami, will operate as a separate unit and keep its product development, marketing, sales and technical support staff as well as its brand, Dell said in a statement.
Alienware will continue to offer machines equipped with AMD processors.The purchase renewed speculation that Dell, which exclusively uses chips made by Intel Corp, may begin using microprocessors by competitor AMD.
Dell spokesman Jess Blackburn said the company was not contemplating switching chip suppliers. "Our strategy in terms of suppliers that we work with is unchanged," Blackburn said. "This doesn't signal that we are changing that."
Dell had revenue of $55.9 billion last year compared with Alienware's $200 million profit.
