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 of low-end AMD CPUs in the marketplace during the last half of fiscal year 2010 as well as by AMD continuing to market their own chipset product lines in place of ours.



CPB.  CPB revenue increased by 20% to $163.9 million for fiscal year 2010 as compared to $136.3 million for fiscal year 2009.  This increase in CPB revenue was primarily driven by sales growth from our embedded products for the automotive and entertainment markets, and was partially offset by a decrease in revenue from development arrangements and royalties from game console-related products in the comparative periods.

 

Fiscal Year 2009 vs. Fiscal Year 2008

 

Revenue was $3.42 billion for fiscal year 2009, compared to $4.10 billion for fiscal year 2008, which represents a decrease of 16%.   A discussion of our revenue results for each of our operating segments is as follows:



GPU Business.  GPU business revenue decreased by 24% to $1.91 billion for fiscal year 2009, compared to $2.52 billion for fiscal year 2008. This decrease resulted from decreased sales of our desktop GPU and memory products, offset by increased sales of our notebook GPU products. Sales of our desktop GPU and memory products decreased by approximately 29% and 59%, respectively, in fiscal year 2009 when compared to fiscal year 2008.  These decreases were primarily due to a decline in the Standalone Desktop market segment as reported in the December 2008 PC Graphics Report from Mercury Research, driven by a combination of market migration from desktop PCs towards notebook PCs and an overall market shift in the mix of products towards lower priced products. This overall market decline translated into a decline of over 20% in the number of units of desktop GPU products that we sold in fiscal year 2009 compared to fiscal year 2008. The decline in desktop GPU revenue also reflects the impact of a slight average sales price regression in our products and a decline in our share position during the middle portion of fiscal year 2009 as a result of increased competition. Memory sales declined as a result of a decline in sales of our high-end desktop GPU products. Sales of our notebook GPU products increased approximately 3% in fiscal year 2009 when compared to fiscal year 2008, due to higher unit sales aided by a market move toward notebook PCs over desktop PCs, offset by a slight decline in average selling prices.  Additionally, the overall global economic recessionary climate contributed to a significant decline in the demand for total graphics during the fourth quarter of fiscal year 2009.



PSB. PSB revenue increased by 18% to $693.4 million for fiscal year 2009, compared to $588.4 million for fiscal year 2008. Our NVIDIA professional workstation product sales increased due to an overall unit increase of approximately 15% in shipments of boards and chips as compared to fiscal year 2008, due to strong demand and our transition from previous generations of NVIDIA Quadro professional workstation products to GeForce
