Thank you, Ruth and good afternoon to all those listening in today.
For the last five years, we have built the technical, operational and financial foundation required to drive our long-term growth strategy. We consistently executed on our product road maps, established deep partnerships with an expanded set of customers, ramped multiple products in leading edge manufacturing technologies and significantly strengthened our balance sheet.
Our strong second quarter results and increased full-year revenue guidance demonstrate how we are successfully scaling our business through our consistent execution.
Looking at the second quarter, revenue grew 26% year-over-year to $1.93 billion, driven by strong demand for our leadership server and client processors. We accelerated our server and mobile processor businesses significantly in the quarter, resulting in Ryzen and EPYC processor revenue more than doubling year-over-year.
Importantly, we met our double-digit server processor market share goal, as Datacenter products accounted for more than 20% of our second quarter revenue.
Turning to our Computing and Graphics segment, second quarter revenue increased 45% year-over-year to $1.37 billion, as growth in Ryzen processor sales more than offset lower graphics sales. We delivered our highest client processor revenue in more than 12 years. Increased working and schooling from home due to COVID-19 resulted in a strong PC market in the quarter.
Although, we believe our growth was largely driven by our 11th straight quarter of market share gains. Desktop processor sales decreased sequentially as anticipated, while revenue in ASP increased year-over-year, as demand for our higher end Ryzen processors drove a richer mix. In mobile, we had record quarterly notebook processor unit shipment and revenue. Sales of our latest Ryzen 4,000 Series processors grew significantly in the quarter, resulting in mobile revenue growing by a strong double-digit percentage sequentially and more than doubling from a year ago as both unit shipments and ASP increased significantly. Multiple third party reviewers have consistently highlighted that our latest notebook processors deliver superior performance and longer battery life, compared to the competition.
As a result of this strong performance, I'm pleased to report that Ryzen 4000 processor revenue has ramped faster than any mobile processor in our history. There are now 54 Ryzen 4000 power notebooks in the market.
We expect to continue accelerating our mobile processor business in the second half of the year as HP and Lenovo ramp their first commercial notebooks powered by Ryzen PRO-4000 Series processors and the second wave of more than 30 ultrathin premium and gaming consumer notebooks launch for multiple OEMs. In Graphics, second quarter revenue declined year-over-year, as strong double-digit increase in mobile GPU sales was more than offset by lower desktop channel sales.
While desktop GPU shipments were lower year-over-year, channel sellout accelerated in the quarter. Mobile GPU revenue growth was driven by a reduction of our RDNA GPUs, highlighted by the launches of new Apple professional and Dell gaming notebooks, featuring our Radeon 5000 M series mobile GPUs. Data center GPU revenue decreased year-over-year.
We expect revenue to increase in the second half of the year, as additional cloud-based visual computing wins ramp and we launch our new CDNA data center GPU architecture optimized for next generation exascale and machine learning workloads.
Turning to our Enterprise, Embedded and Semi-Custom segment, revenue of $565 million decreased 4% year-over-year due to lower semi-custom sales. Sequentially, revenue increased 62%, driven by record quarterly server processor sales and increased semi-custom product revenue. In semi-custom, we passed an important milestone in the second quarter as we began initial production and shipments of our next generation game console SOCs.
We expect strong second half semi-custom growth as we ramp production to support the holiday launches of the new PlayStation 5 and Xbox series X consoles.
Turning to server, our focus since launching our EPYC processors has been on building a solid foundation to drive long-term growth.
Our strategy is grounded in driving broad, high volume adoption with widespread support from industry leading cloud and hardware providers. We passed a significant milestone in the quarter, as we achieved our double-digit server processor unit share goal, based on broad adoption across cloud, enterprise and HPC customers. In cloud, multiple hyperscale customers ramped second generation EPYC processors into high volume production in the quarter to power both their internal infrastructure and publicly available instances. Microsoft announced they have added EPYC processors to power their office online applications used by more than 200 million monthly users. Tencent ramped up multiple millions of EPYC processor powered virtual machines to support enhanced collaboration services. Google announced that EPYC processors were being used exclusively to power their unique confidential Computing VMs that encrypt data while it is being processed. And AWS launch global availability of new compute optimized EPYC based EC2 instances. In enterprise, we have significantly expanded our TAM as the number of AMD platforms has increased by more than 40% so far this year. Recent additions include Dell and HPE introducing multiple hyperconverged infrastructure solutions, Lenovo launching dual socket servers for financial, retail and manufacturing and video selecting AMD EPYC processors to power its latest DGX AI platforms.
We also secured new HPC wins based on the leadership performance and scalability of second Gen EPYC processors. Public highlights include new wins with leading research institutions including Indiana University, Purdue and CERN, as well as Amazon, IBM, Microsoft and Oracle all announcing cloud-based HPC offerings powered by EPYC processors.
We are pleased with the momentum in our server business and expect to continue gaining share as additional second Gen EPYC platforms and cloud deployments ramp to volume in the second half of the year. We remain on track to begin shipping our next generation Milan server processor featuring ZEN3 late this year. In closing, I want to thank our employees and partners for the strong execution during this unprecedented time as we continue to focus on delivering on our commitments.
While there continues to be some macroeconomic uncertainty and pockets of demand softness, our product portfolio is very strong and our markets are resilient.
We are on track to deliver strong growth in the second half of the year, driven by our current product portfolio and initial shipments of our next generation ZEN 3 CPUs and RDNA to GPUs that are on track to launch in late 2020. I am very proud of the progress we have made over the last few years, placing AMD on a long-term growth trajectory. I'm even more excited about the opportunities in front of us as we enter our next phase of growth driven by accelerating our business in multiple markets. We remain focused on consistently gaining share across the $79 billion market for our high-performance products.
We are investing significantly and have added resources to further extend our leadership IP and go to market capabilities, as we pursue our ambitious goal to make AMD a best-in-class growth franchise.
Now I'd like to turn the call over to Devinder to provide some additional color on our second quarter financial performance. Devinder?
