Unless or otherwise noted, all references to market research and market share numbers throughout the call come from Mercury Research or Jon Peddie Research. During this call, we will discuss non-GAAP financial measures.

With that, let's begin. After 5 consecutive quarters of sequential revenue growth, fourth quarter revenue was negatively impacted by the global disk drive shortage caused by the flooding in Thailand, which affected the mainstream GPU segment more than anticipated. Shipments by some PC OEMs were reduced, and higher disk drive prices constrained the ability of some PC OEMs to include a GPU in their systems. Additionally, the Tegra 2 mobile business declined more rapidly than expected ahead of devices based on the Tegra 3 processor ramping into production in the first quarter of calendar year 2012.
However, despite tough economic conditions and the exiting of our chipset business, NVIDIA recorded very good results for our full fiscal year 2012. First, our overall GP -- our overall business grew 33%, excluding the chipset business we've been exiting. Discrete GPUs, including GeForce, Quadro and Tesla grew sharply over the year. GPU attach rates remained strong at 53% of consumer PCs and 36% overall, according to Mercury Research data.A resurgent PC gaming market saw games like Battlefield 3 and Modern Warfare 3 record over $1 billion in sales in their first week on the shelves. At the time of the launch of Battlefield 3, over 80% of gamers were below the recommended hardware specification to play the game, driving a significant increase in gamer GPU revenues over the year. Our Professional Solutions Business had a record revenue year driven by large adoption of the Fermi generation of Quadro workstation products, as well as growth in emerging design economies such as India and China. Our Tesla products were selected to power the world's fastest supercomputers, including Oak Ridge National Laboratory's upcoming Titan supercomputer. In addition, we made major strides in speeding up GPU computing applications support and code porting through our open HPC and directives initiatives. And in one of our most important achievements for the year, we established a position in the mobile market. Tegra products captured share in Tier 1 tablets and smartphones. Over the course of the year, Tegra products shipped in 14 phones, 34 tablets and in 18 of the top 20 carriers. We designed and shipped 3 generations of Android devices. With Tegra 2, we were the first to ship dual-core mobile processors. And now with Tegra 3, we are the first to ship quad-core processors. The Tegra mobile processor has grown into a multi-hundred million dollar business. Read the rest of this transcript for free on seekingalpha.com
