Advanced Micro Devices (AMD) has agreed to buy Canadian graphics chip vendor ATI Technologies for about US$5.4 billion in cash and stock, the companies announced Monday.AMD sees the merger as a way to offer integrated products for the mobile computing and consumer electronics markets, it said. From 2008 onward, it intends to offer a new range of integrated processing and graphics chips for custom applications, it said. The acquisition, which is subject to shareholder and regulatory approvals, would turn AMD into one of the world\u2019s largest providers of graphics chips. ATI reported net income of $31.9 million on revenue of $652.3 million during its fiscal third quarter, which ended on May 31. At that time, the company said revenue for the current quarter would be between $620 million and $690 million.In the last fiscal year, a combined AMD and ATI would have made sales of around $7.3 billion, the companies said.\n\n\n\n\n\n\n\n\n\nAMD CEO Hector Ruiz and ATI CEO Dave OrtonATI and AMD expect to complete the deal in the fourth quarter, subject to approval of ATI shareholders and U.S. and Canadian regulators.Rumors that AMD would buy ATI have circulated for a couple of months. If approved, the deal will add significantly to AMD\u2019s product line, bringing in a lineup of cutting-edge graphics chips and chipsets that include integrated graphics capabilities. Chipsets are the component on a PC motherboard that link a processor with main memory and other components, such as a hard disk.These additions to AMD\u2019s product line will help the company better match rival Intel, which offers its own line of chipsets with graphics capabilities. But the deal will likely threaten AMD\u2019s relationship with Nvidia, ATI\u2019s main rival in the graphics space and an important AMD partner.AMD will take on new debt of approximately $2.5 billion to finance the deal. ATI has agreed to pay AMD a termination fee of $162 million if it backs out.-Peter Sayer and Sumner Lemon, IDG News Service (Paris Bureau)This article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
