Thanks, Pat, and welcome back to Intel. It has been an honor to lead this incredible company and its talented team. It gives me great confidence in Intel's future knowing that I'll be passing the baton to Pat, whose technology expertise, industry knowledge, execution track record, and commitment to our company is indisputable. Over the last two years, we made significant progress on our strategy to transform Intel into a multi-architecture XPU company to move from silicon to solutions and to contemporize our IDM model. I am proud of what we're able to achieve together as an Intel team in a relatively short period of time and echo Omar's words that Intel is in a strong strategic and financial position as we make this transition. As demonstrated by the results we announced today, demand for Intel's innovative technologies remains very strong and our investments to capitalize on future growth opportunities are paying off.
Our Q4 results significantly exceeded our expectations capping off our fifth consecutive year of record revenue. We generated $20 billion in revenue and $1.52 in EPS, exceeding our guidance by $2.6 billion and $0.42, respectively. For the full year, we delivered $77.9 billion in revenue, up 8% and $5.30 in EPS, up 9%. The client, data center, memory, and Mobileye businesses each set all-time revenue records.
In Q4, we continued to advance our three strategic priorities; improving our execution to strengthen our core business, extending our reach to accelerate growth and redefine our position in the industry, and continuing to thoughtfully deploy capital to create value for our shareholders. Let me briefly discuss some of the highlights.
Starting with improving our execution to strengthen our core business, let me start with an update on process technology and our product roadmap. Over the last few years, we've been following the IDM model to ensure we can deliver a predictable cadence of leadership products, preserve our IDM advantage, continue to invest in process technology leadership, and generate attractive returns on capital. This evolution includes a disaggregated design strategy, adoption of standard industry processes and common tools, flows, and methods, and deeper engagement with the industry ecosystem. In July, we highlighted a challenge with our 7-nanometer technology and started a process to improve it while evaluating the best approach for our 2023 product lineup. Since that time, we have made tremendous progress on our 7-nanometer technology. When 7-nanometer was originally defined, the flow contained a particular sequence of steps that contributed to the defect issue we discussed in July. By re-architecting these steps, we've been able to resolve the defects. As part of this work over the last six months, we also streamlined and simplified our 7-nanometer process architecture to better ensure we'll be able to deliver on our 2023 product roadmap. The inline data we have been collecting and our pipeline of proven yield development projects gives us confidence in our ability to deliver on our commitments going forward. At the same time, as Pat mentioned, we will continue to leverage the relationships we've developed over the years with our external foundry partners and believe they can play a larger role in our product roadmap given our disaggregated designs. Once Pat has had a chance to join, he'll further assess our analysis and drive the final manufacturing decision for our 2023 CPU products. Therefore, we'll communicate that decision soon after he takes over, but not today. Turning to products, we've qualified several new products in the fourth quarter and we have an incredibly exciting lineup of CPUs for 2021 and 2022.
Just a couple of weeks ago at CES, we introduced more than 50 processors resulting in more than 500 new designs for laptops and desktops coming to market in 2021. We are also seeing tremendous market response for PCs based on our new 11th Gen Intel Core Tiger Lake Processors. Our PC customers now have more than 150 Tiger Lake based systems in the market, well ahead of expectations. We believe we gained market share as PC CPU units grew an impressive 33% in the quarter. In a market where competitors are seeing supply challenges, this is a powerful example of the incredible value and scale of our factory network as we continue to deliver greater performance and cost efficiencies for our customers.
Moving to data center, we are now shipping our first 10-nanometer based Xeon Scalable CPU Ice Lake and will be ramping volume through the first quarter. Customers are going to see significant value in Ice Lake across cloud, network, and edge workloads with excellent performance improvement and innovations such as PCIe Express Gen 4, next generation Intel Optane Persistent Memory and security enhancements such as SGX. As we look ahead, we are excited about the capabilities we are bringing to customers with Alder Lake for mobile and desktop PCs and Sapphire Rapids for the data center. These products take advantage of our Enhanced SuperFin process technology and numerous architectural improvements and both are broadly sampling to customers. We will qualify Alder Lake desktop and notebook for production and begin our volume ramp in the second half of 2021 and we expect production qualification of Sapphire Rapids at the end of 2021. In the expanded market opportunity in front of us, CPUs are critical, but multiple architectures or XPUs will be required to help customers optimize for specific workloads.
We had a big XPU leap in the fourth quarter as we entered the discrete graphics market with Intel Iris Xe MAX graphics, Intel's first Xe-based discrete GPU. We are now shipping discrete graphics into thin and light notebooks from Acer, Asus, and Dell and we introduced our first discrete GPU for the data center, which is already delivering great cloud gaming experiences for customers such as Tencent.
We also announced the gold release of oneAPI, our cross-industry open standards-based unified programming model that delivers a common developer experience across architectures. Second, we've made strong progress extending our reach to accelerate our growth. Over the past several years, we have been making investments that have positioned us to lead key technology inflections such as AI, 5G network transformation, and the intelligent autonomous edge. We infuse AI capabilities into everything we make from the cloud to PCs and we see tremendous growth prospects as we build our position in data center training to complement the strength of our Intel Xeon for inference. We made a significant step in AI this quarter when Amazon announced EC2 instances that will leverage up to eight of our Habana Gaudi AI training accelerators and deliver up to 40% better price performance than current GPU-based EC2 instances for machine learning workloads. We've also invested to drive networking workload convergence on Intel silicon. In 2020, we expanded our footprint into the Radio Access Network delivering Xeon SoCs, FPGAs, and custom solutions for 5G base station designs and reaching our goal of 40% share, two years ahead of our original target. Today, we are the leading network silicon provider winning in wireless, enterprise, and cloud networks and delivering $6 billion in revenue this year, up approximately 20% versus 2019.
Finally, we have enviable assets to lead the explosive growth of intelligent and autonomous edge computing. Our IOTG and Mobileye businesses have a combined annual revenue of $4 billion. Mobileye delivered a record fourth quarter and had an explosive start to 2021 with a number of exciting CES announcements. Third, we've maintained our discipline in thoughtfully allocating our shareholders' capital. Since 2015, we have grown revenue by more than $22 billion and more than doubled EPS. We've driven spending from 36% of revenue to 25% of revenue, while investing in manufacturing capacity expansion, adding more than $1 billion of R&D targeted to higher growth initiatives, and focusing our product portfolio. As a result, we anticipate approximately $12 billion in proceeds from our NAND and McAfee exits over time. At the same time, we've been delivering substantial capital returns to shareholders, including $19.8 billion in 2020 alone through dividends and share buybacks, the latter of which included a $10 billion accelerated share repurchase announced in August. Building on this, today, we announced that we are increasing our annual dividend by $0.07 or 5% from $1.32 to $1.39 per share. Before I pass it to George for more details on our fourth quarter results, I want to reiterate that I couldn't be more proud of the team at Intel and I cherish the time I've spent here.
I look forward to watching Pat and the team's continued progress as they build on Intel's purpose to deliver breakthrough technology that enriches the lives of everyone on the planet. I also thank our investors and analysts on the line today for their continued support of Intel and for our valued engagements over the years.
