Intel Corporation (NASDAQ:INTC) has been performing extremely well recently. The company has begun its move into the mobile market and it’s stock price has risen in the first weeks of the new year. The former Chief Executive of Advanced Micro Devices, Inc. (NYSE:AMD) has a little something to say about that, and he’s saying it in a new book.

Hector Ruiz, who led AMD from 2002 until 2008, has released a book called Slingshot, which details his experience in the fight against Intel in the semiconductor market. The book alleges that Intel was involved in illegal business practices during its fight against Advanced Micro Devices, Inc. (NYSE:AMD).

AMD sued Intel for anti trust violations during Ruiz’ reign at the head of the company. Intel never admitted any wrongdoing in the case, but the firm did eventually pay AMD $1.25 billion in a 2009 settlement. The new book from Ruiz seeks to remind people of the battle, and bring to light some of the strategies Intel was using to ensure market supremacy.

According to SlingshotAMD released a great lone of chips early in the last decade, but despite initial excitement from computer makers, the line up never resulted in increased demand. Ruiz alleges that the reluctance stemmed from financial incentives and threats from Intel Corporation (NASDAQ:INTC).

This book is unlikely to cause much trouble for Intel now. The law suits are over, and the processor market has changed substantially since Ruiz sat at the helm of AMD. Intel is now coming from a position far behind its competitors in the mobile market. That market is thought by almost everyone to be the future of the processor market.

Neither of the two firms have had a very good time on the market in the last twelve months. Stock in Advanced Micro Devices, Inc. (NYSE:AMD) has fallen by more than 60% in the last year, while stock in Intel Corporation (NASDAQ:INTC) has fallen by more than 20% in the same period. Investor angst about the future of the processor market has had a big effect on the shares of both companies.

The book, which was co-written with the journalist Lauren Villagran, is to be published on April 23. It clocks in at just around 200 pages long and discusses Riaz childhood and education as well as other challenges he faced at the head of AMD, covering much more than just the Intel anti trust case.
