What is the expected initial production shipment date for Intel's first seven-nanometer product, a client CPU, 
liver product leadership for our customers, and we are taking the right steps to produce a strong lineup of leadership products.
We will continue to invest in our future process technology road map, but we will be pragmatic and objective in deploying the process technology that delivers the most predictability and performance for our customers, whether that be on our process, external foundry process, or a combination of both. Our advanced packaging technologies, combined with our disaggregated architecture, give us tremendous flexibility to use the process technology that best serves our customers. As an example, our data center GPU design, Ponte Vecchio, will now be released in late 2021 or early 2022, utilizing external and internal process technologies, combined with our world-leading packaging technologies. We now expect to see initial production shipments of our first Intel-based seven-nanometer product, a client CPU, in late '22 or early '23.
We are also focused on maintaining an annual cadence of significant product improvements independent of our process road map, including the holiday refresh window of 2022. In addition, we expect to see initial production shipments of our first Intel-based seven-nanometer data center CPU design in the first half of '23. Finally, while process technology is very important, it is only one of the six technology pillars of innovation that drive differentiation in our products. You will hear more about advances across all six technology pillars: process, packaging, architecture, memory, interconnect and security/software at the upcoming Intel Architecture Day.
Last, we are focused on the thoughtful allocation of your capital. We are investing to grow our capabilities even as we deliver significant free cash flow this year. Since 2015, we have grown R&D spending by more than $1 billion while divesting non-core assets and reducing overall spending as a percentage of revenue by 9 points. We also look for opportunities to augment our product lines and speed the pace at which we can grow the company.
As discussed earlier, we acquired Moovit this quarter, investing approximately $900 million to dramatically accelerate our capability to capitalize on the $160 billion Mobility-as-a-Service opportunity. We also announced a $250 million investment in Jio Platforms, a high-speed wireless connectivity, and digital services provider, to help fuel digital transformation in India. Our purpose to deliver world-changing technology that enriches the lives of every person on Earth has never been more essential, but the global problems we face are bigger than any one company can solve alone. That's why we established 2030 corporate responsibility goals, which call for a collective response to revolutionize health and safety, make technology fully inclusive, and help address climate change.
We've also committed more than $50 million and extended our expertise, global reach, and influence to combat COVID-19, as well as social injustice. The early results of our pandemic response technology initiative, which we announced earlier this week, underscore Intel's unique ability to partner and collectively solve critical problems. In closing, I want to thank all our employees who are working through this challenging time to deliver our purpose and support our customers.

Thanks, Bob, and good afternoon, everyone. The atypical seasonal effects of COVID-related demand for mobility products and data center infrastructure continued in Q2, resulting in record Q2 revenue for CCG, DCG, and memory. Revenue came in at $19.7 billion, up 20% year on year, and $1.2 billion higher than guided. Data-centric revenue of $10.2 billion, up 34% year on year, represented 52% of our total revenue, an all-time high.
Strong demand for NAND and 5G networking solutions and richer server mix drove most of the upside versus our expectations. Q2 PC-centric revenue was $9.5 billion, up 7% year on year on strong notebook PC sales enabled through increased manufacturing supply on capacity additions ove
