becomes available that causes us to determine that a loss in any of our pending litigation, investigations or settlements is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with U.S.GAAP. However, the actual liability in any such litigation or investigations may be materially different from our estimates, which could require us to record additional costs.

Revenue

 

Fiscal Year 2010 vs. Fiscal Year 2009

 

         Revenue was $3.33 billion for the fiscal year 2010 and $3.42 billion for fiscal year 2009, a decrease of 3%.   A discussion of our revenue results for each of our operating segments is as follows:



GPU Business. GPU Business revenue decreased by 8% to $1.76 billion for fiscal year 2010 compared to $1.91 billion for fiscal year 2009.  The decrease was primarily the result of a decline in sales of notebook GPUs, offset by a slight increase in sales of memory products.  Sales of our notebook GPU products decreased by approximately 31% while sales of our desktop GPU products were essentially flat, increasing by only 1%, and our memory products increased by 38% as compared to fiscal year 2009.   The decrease in notebook GPU revenue was driven primarily by a combination of a decline in unit demand and a decline in average selling price (“ASPs”) as a result of increased competition in the marketplace and due to share losses we experienced within the notebook segment, during calendar year 2009 compared to calendar year 2008 as reported in the November PC Graphics 2009 Report from Mercury Research.  The very slight increase in sales of our desktop GPU products resulted from an increase in unit volume in fiscal year 2010, which was driven by a strong unit sales recovery during the fourth quarter of fiscal year 2010, offset by a decline in ASPs for the full fiscal year, which was driven by pricing pressures in the marketplace for our high-end and mainstream products. Sales of our memory products increased as a result of the overall increase in desktop GPU unit demand.



PSB. PSB revenue decreased by 26% to $510.2 million for the fiscal year 2010 as compared to $693.4 million for fiscal year 2009.  Both the ASPs and unit shipments of professional workstation products decreased, primarily due to the relatively slow recovery of corporate spending following the economic recession that began during fiscal year 2009.  



MCP Business. MCP Business revenue increased by 33% to $871.6 million for fiscal year 2010 as compared to $655.6 million for fiscal year 2009.  The increase was a result of increased sales of our Intel-based platform products by over 100%, offset by a decrease in sales of our AMD-based platform products by approximately 12%. The increase in Intel-based platform product sales was driven by sales of our ION products. The decrease in AMD-based platform products was driven by limited availability
