Lisa Su
President and Chief Executive Officer at Advanced Micro Devices
Thank you, Laura, and good afternoon to all those listening in today. Our business performed extremely well in the third quarter as our leadership product portfolio and strong execution, drove record quarterly revenue, operating income, net income and earnings per share. We delivered our fifth straight quarter of greater than 50% year-over-year revenue growth with each of our businesses growing significantly year-over-year and data center sales more than doubling. Third quarter revenue grew 54% to $4.3 billion. Gross margin expanded by more than 4 percentage points, and operating income doubled year-over-year.
Turning to our Computing and Graphics segment. Third quarter revenue increased 44% year-over-year to $2.4 billion, driven by our latest generation Ryzen, Radeon, and AMD Instinct processors. In Client computing, sales grew by a strong double-digit percentage year-over-year and declined slightly sequentially. Ryzen 5000 processors shipments increased by a double-digit percentage sequentially resulting in a richer product mix as we believe we gained revenue share for the sixth straight quarter.
In desktops, we launched our Ryzen 5000 processors with integrated Radeon graphics for the channel to strong demand as third-party reviews highlighted the leadership computing and graphics capabilities and energy efficiency of these processors. In notebooks, Acer, ASUS, HP, and Lenovo all expanded their mobile offerings powered by Ryzen 5000 mobile processors as we continue gaining momentum in the premium consumer, gaming, and commercial markets. Commercial client growth year-over-year was based on new deployments across public sector and Fortune 1000 technology, energy, and automotive customers as the number of AMD-based commercial notebook designs available from the largest OEMs increased significantly year-over-year.
We're also seeing strong growth in the workstation market. According to IDC, Threadripper PRO processors now power the best-selling workstations in their category in both North America and EMEA as we continue winning high volume deployments across key verticals including media and entertainment, engineering, architecture, and automotive. In Graphics, revenue more than doubled year-over-year and grew by a strong double-digit percentage sequentially driven by shipments of our next generation AMD CDNA 2 data center GPUs and demand for Radeon 6000 GPUs in the channel. AMD RDNA 2 GPU sales grew significantly in the quarter as we ramped production and expanded our top to bottom portfolio with the launch of the mid-range Radeon RX 6600 XT cards that deliver leadership 1080p gaming performance at their price point.
Data center graphics revenue more than doubled year-over-year and quarter-over-quarter led by shipments of our new AMD CDNA 2 GPUs for the Frontier Exascale supercomputer at Oak Ridge National Laboratory. Frontier was architected specifically to deliver breakthrough HPC and AI compute performance, and provide a blueprint for how supercomputing, enterprise, and cloud customers can enable Exascale-level performance over the coming years by combining AMD CPUs, GPUs, and software. We are very pleased with the performance of our AMD CDNA 2 GPUs and look forward to providing more details on their leadership performance next month.
Turning to our Enterprise, Embedded, and Semi-Custom segment. Revenue increased 69% year-over-year to $1.9 billion, driven by strong growth in EPYC processor and semi-custom sales. Semi-Custom revenue grew sequentially and year-over-year as demand for the latest Microsoft and Sony consoles remains very strong. We expect semi-custom revenue to increase sequentially in the fourth quarter as we further ramp supply to address the ongoing game console demand.
Turning to server. We delivered our sixth straight quarter of record server processor revenue as sales more than doubled year-over-year and grew by a significant double-digit percentage sequentially. 3rd Gen EPYC processors continue ramping faster than the prior generation and contributed the majority of our server CPU revenue in the quarter. In Cloud, multiple hyperscalers expanded their 3rd Gen EPYC processor deployments to power their internal workloads and both Microsoft Azure and Google announced multiple new AMD-powered instances. Cloudflare, Vimeo, and Netflix also all recently announced new deployments powered by EPYC processors with Netflix highlighting how they doubled their streaming throughput per server, while also reducing their TCO.
Enterprise growth was particularly strong in the quarter as the more than 100 3rd Gen EPYC processor platforms from Dell, HPE, Lenovo, Supermicro, Cisco, and others ramp into broader end-customer deployments. We expanded our wins in the quarter with Fortune 1000 financial services, automotive, and aerospace companies and see significant ongoing growth opportunities as our enterprise server pipeline has more than doubled year-over-year.
In supercomputing, we won multiple installations in the quarter, highlighted by Argonne National Laboratory selecting 3rd Gen EPYC processors to power the new Polaris supercomputer that will be used to test and optimize software in preparation for future Exascale class systems. Overall, we are very pleased with the momentum we have built in our data center business as server CPU and GPU revenue grew to a mid-20s percent of overall revenue in the quarter.
Turning to our Xilinx acquisition. We are making good progress towards securing the required regulatory approvals and remain on track to close by the end of the year. Thie Xilinx acquisition will provide significant benefits to AMD, including expanding our product portfolio with leadership adaptive computing and AI solutions, and further diversifying our customer base into complementary markets including wired and wireless communications, industrial, and automotive.
In closing, our record third quarter results and the significant acceleration of our business in 2021 demonstrate that we have the right products and strategies to drive best-in-class growth and significant shareholder returns. We continue growing faster than the market, driven by our consistent execution and the investments we have made to build leadership products. Our supply chain team has executed extremely well in a challenging environment, delivering incremental supply throughout the year, supporting our strong revenue growth. We are also investing significantly to secure additional capacity to support our long-term growth. Our product portfolio and road maps have never been stronger and I look forward to sharing more details about our next-generation server CPUs and GPUs at our Accelerated Data Center Premiere on November 8th.
Now I'd like to turn the call over to Devinder to provide some additional color on our third quarter financial performance. Devinder?
