Executive Vice President and Chief Financial Officer at NVIDIA
Thanks, Jensen. Gaming revenue of $1.83 billion was up 16% sequentially and down 46% from a year ago. Fiscal year revenue of $9.07 billion, down 27%. Sequential growth was driven by the strong reception of our 40 Series GeForce RTX GPUs, based on the Ada Lovelace architecture. The year-on year decline reflects the impact of channel inventory correction, which is largely behind us. And demand in the seasonally strong fourth quarter was solid in most regions. While China was somewhat impacted by disruptions related to COVID we are encouraged by the early signs of recovery in that market.
Gamers are responding enthusiastically to the new RTX 490, 408, 470 Ti desktop GPUs with many retail and online outlets quickly selling out of stock. The flagship 490 has quickly shot up in popularity on steam, claimed the top spot for the Ada architecture, reflecting gamers desire for high-performance graphics. Earlier this month, the first phase of gaming laptops, based on the Ada architecture reached retail shelves delivering NVIDIA's largest-ever generational leap in performance and power efficiency. For the first time we are bringing enthusiast-class GPU performance to laptops as slim as 14 inches, a fast-growing segment previous limited to basic task and apps.
In another first, we are bringing the 95 [Phonetic] CPUs our most performance models to laptops, thanks to the power efficiency of our 5th generation Max Q technology. All-in RTX 40 Series GPUs, the power over 170 gaming and creator laptops setting up for a great [indecipherable]. There are now over 400 games and applications supporting NVIDIA's RTX technologies for real-time ray tracing and AI-powered graphics. The Ada architecture, features DLSS 3 our third-generation AI-powered graphics which massively raise performance. One of the most advanced games Cyberpunk 2077 recently added DLSS 3 enabling a three to four x boost in frame rate performance at 4K resolution.
Our GeForce NOW cloud gaming service continues to expand in multiple dimensions, users, titles and performance. It now has more than 25 million members in over 100 countries. Last month, it enabled RTX 4080 graphics horsepower in the new high-performance ultimate membership tier. Ultimate members can stream at up to 240 frames per second from a cloud with full ray tracing in DLSS 3. And just yesterday, we made an important announcement with Microsoft. We agreed to a 10-year partnership to bring the GeForce NOW Microsoft line-up of Xbox PC games which includes blockbusters like Minecraft, Credo [Phonetic] and Flight Simulator. And upon the close of Microsoft's Activision acquisition we will add titles Call of Duty and Overwatch.
Moving to Pro visualization, revenue of $226 million was up 13% sequentially and down 65% from a year-ago. Fiscal year revenue of $1.54 billion was down 27%. Sequential growth was driven by desktop workstations with strength in the automotive and manufacturing industrial verticals. The year-on-year decline reflects the impact of the channel inventory correction, which we expect to end in the first half of the year.
Interest in NVIDIA's Omniverse continues to build with almost 300,000 downloads so far, 185 connectors to third-party design applications. The latest release of Omniverse has a number of features and enhancements, including support for 4K real-time path tracing, Omniverse search for AI-powered search through large untied 3D databases and Omniverse cloud containers for AWS.
Let's move to automotive. Revenue was a record $294 million, up 17% and up 135% from a year ago. Sequential growth was driven primarily by AI, automotive solutions with program ramps at both electric vehicle and traditional OEM customers helped drive this growth. Fiscal year revenue of $903 million was up 16% [Phonetic]. At CES, we announced a strategic partnership with Foxconn to develop automated and autonomous vehicle platforms. This partnership will provide scale for volume manufacturing to meet growing demand for the NVIDIA DRIVE platform. Foxconn will use NVIDIA DRIVE, Hyperion compute and center architecture for its electric vehicles.
Foxconn will be a tier-one manufacturer producing electronic control units based on the NVIDIA DRIVE Orin for the global automotive OEM. We also reached an important milestone this quarter. The NVIDIA DRIVE operating system received safety certification from TUV SUD, one of the most experienced and rigorous assessment bodies in the automotive industry. With industry-leading performance and functional safety, our platform meets the higher standards required for autonomous transportation.
Moving to the rest of the P&L, GAAP gross margin was 63.3% and non-GAAP gross margin was 66.1%. Fiscal year GAAP gross margin was 56.9% and non-GAAP gross margin was 59.2%. Year-on year Q4 GAAP operating expenses were up 21% and non-GAAP operating expenses were up 23%, primarily due to the higher compensation and data center infrastructure expenses. Sequentially. GAAP operating expenses were flat and non-GAAP operating expenses were down 1%. We plan to keep them relatively flat at this level over the coming quarters.
Full year GAAP operating expenses were up 15% and non-GAAP operating expenses were up 31%. We returned $1.15 billion to shareholders in the form of share repurchases and cash dividends. At the end of Q4, we had approximately $7 billion remaining under our share repurchase authorization through December 2023.
Let me look to the outlook for the first quarter of fiscal '24. We expect sequential growth to be driven by each of our four major market platforms. Led by strong growth in data center and gaming. Revenue is expected to be $6.5 billion, plus or minus 2%. GAAP and non-GAAP gross margins are expected to be 64.1% and 66.5% respectively, plus or minus 50 basis-points.
GAAP operating expenses are expected to be approximately $2.53 billion. Non-GAAP operating expenses are expected to be approximately $1.78 billion. GAAP and non-GAAP other income and expenses are expected to be an income of approximately $60 million excluding gains and losses of non-affiliated investments. GAAP and non-GAAP tax rates are expected to be 13% plus or minus 1% excluding any discrete items.
Capital expenditures are expected to be approximately $350 million to $400 million for the first quarter. And in the range of $1.1 billion to $1.3 billion for the full fiscal year 2024. Further financial details are included in the CFO commentary and other information available on our IR website.
In closing, let me highlight upcoming events for the financial community. We will be attending the Morgan Stanley Technology Conference on March 6 in San Francisco and the Cowen Healthcare Conference on March 7 in Boston. We will also host GTC virtually which as you know is kicking off on March 21. Our earnings call to discuss the results of our first quarter of fiscal year '24 is scheduled for Wednesday, May 24.
Now we will open up the call for questions. Operator, would you please poll for questions.
