Yesterday, Intel launched its Xeon 6 family of server processors based on P-cores manufactured on Intel 3 node. While the early reviews seem promising, Intel is preparing a more advanced generation of processors that will make or break its product and foundry leadership. Codenamed "Clearwater Forest," these CPUs are expected to be the first high-volume production chips based on the Intel 18A node. We have pictures of the five-tile Clearwater Forest processor thanks to Tom's Hardware. During the Enterprise Tech Tour event in Portland, Oregon, Tom's Hardware managed to take a picture of the complex Clearwater Forest design. With compute logic built on 18A, this CPU uses Intel's 3-T process technology, which serves as the foundation for the base die, marking its debut in this role. Compute dies are stacked on this base die, making the CPU building more complex but more flexible.

The Foveros Direct 3D and EMIB technologies enable large-scale integration on a package, achieving capabilities that previous monolithic single-chip designs could not deliver. Other technologies like RibbonFET and PowerVia will also be present for Clearwater Forest. If everything continues to advance according to plan, we expect to see this next-generation CPU sometime next year. However, it is crucial to note that if this CPU shows that the high-volume production of Intel 18A is viable, many Intel Foundry customers would be reassured that Intel can compete with TSMC and Samsung in producing high-performance silicon on advanced nodes at scale.

Intel has announced the cancellation of its 20A node for Foundry customers, as well as shifting majority of Arrow Lake production to external foundries. The tech giant will instead focus its resources on the more advanced 18A node while relying on external partners for Arrow Lake production, likely tapping TSMC or Samsung for their 2 nm nodes. The decision follows Intel's successful release of the 18A Process Design Kit (PDK) 1.0 in July, which garnered positive feedback from the ecosystem, according to the company. Intel reports that the 18A node is already operational, booting operating systems and yielding well, keeping the company on track for a 2025 launch. This early success has enabled Intel to reallocate engineering resources from 20A to 18A sooner than anticipated. As a result, the "Arrow Lake processor family will be built primarily using external partners and packaged by Intel Foundry".

The 20A node, while now cancelled for Arrow Lake, has played a crucial role in Intel's journey towards 18A. It served as a testbed for new techniques, materials, and transistor architectures essential for advancing Moore's Law. The 20A node successfully integrated both RibbonFET gate-all-around transistor architecture and PowerVia backside power delivery for the first time, providing valuable insights that directly informed the development of 18A. Intel's decision to focus on 18A is also driven by economic factors. With the current 18A defect density already at D0 <0.40, the company sees an opportunity to optimize its engineering investments by transitioning now. However, challenges remain, as evidenced by recent reports of Broadcom's disappointment in the 18A node. Despite these hurdles, Intel remains optimistic about the future of its foundry services and the potential of its advanced manufacturing processes. The coming months will be crucial as the company works to demonstrate the capabilities of its 18A node and secure more partners for its foundry business.

Intel today announced that its lead products on Intel 18A, Panther Lake (AI PC client processor) and Clearwater Forest (server processor), are out of the fab and have powered-on and booted operating systems. These milestones were achieved less than two quarters after tape-out, with both products on track to start production in 2025. The company also announced that the first external customer is expected to tape out on Intel 18A in the first half of next year.

"We are pioneering multiple systems foundry technologies for the AI era and delivering a full stack of innovation that's essential to the next generation of products for Intel and our foundry customers. We are encouraged by our progress and are working closely with customers to bring Intel 18A to market in 2025." -Kevin O'Buckley, Intel senior vice president and general manager of Foundry Services

Intel Corporation today reported second-quarter 2024 financial results. "Our Q2 financial performance was disappointing, even as we hit key product and process technology milestones. Second-half trends are more challenging than we previously expected, and we are leveraging our new operating model to take decisive actions that will improve operating and capital efficiencies while accelerating our IDM 2.0 transformation," said Pat Gelsinger, Intel CEO. "These actions, combined with the launch of Intel 18A next year to regain process technology leadership, will strengthen our position in the market, improve our profitability and create shareholder value."

"Second-quarter results were impacted by gross margin headwinds from the accelerated ramp of our AI PC product, higher than typical charges related to non-core businesses and the impact from unused capacity," said David Zinsner, Intel CFO. "By implementing our spending reductions, we are taking proactive steps to improve our profits and strengthen our balance sheet. We expect these actions to meaningfully improve liquidity and reduce our debt balance while enabling us to make the right investments to drive long-term value for shareholders."

During the 69th annual IEEE International Electron Devices Meeting (IEDM), Intel demonstrated some of its latest transistor design and manufacturing advancements. The first one in line is the 3D integration of transistors. According to Intel, the company has successfully stacked complementary field effect transistors (CFET) at a scaled gate pitch down to 60 nm. With CFETs promising thinner gate channels, the 3D stacked CFET would allow for higher density by going vertically and horizontally. Intel's 7 node has a 54 nm gate pitch, meaning CFETs are already close to matching production-ready nodes. With more time and development, we expect to see 3D stacked CFETs in the production runs in the coming years.

Next, Intel has demonstrated RibbonFET technology, a novel approach that is the first new transistor architecture since the introduction of FinFET in 2012. Using ribbon-shaped channels surrounded by the gate, these transistors allow for better control and higher drive current at all voltage levels. This allows faster transistor switching speeds, which later lead to higher frequency and performance. The width of these nanoribbon channels can be modulated depending on the application, where low-power mobile applications use less current, making the channels thinner, and high-performance applications require more current, making the channels wider. One stack of nanoribbons can achieve the same drive current as multiple fins found in FinFET but at a smaller footprint.

Intel is about to turn chipmaking upside down with PowerVia, a new approach to delivering power that required a radical rethink to both how chips are made and how they are tested. For all the modern history of computer chips, they've been built like pizzas—from the bottom up, in layers. In the case of chips, you start with the tiniest features, the transistors, and then you build up increasingly less-tiny layers of wires that connect the transistors and different parts of the chip (these are called interconnects). Included among those top layers are the wires that bring in the power that makes the chip go.

When the chip is done, you flip it over, enclose it in packaging that provides connections to the outer world, and you're ready to put it in a computer. Unfortunately, this approach is running into problems. As they get smaller and denser, the layers that share interconnects and power connections have become an increasingly chaotic web that hinders the overall performance of each chip. Once an afterthought, "now they have a huge impact," says Ben Sell, vice president of Technology Development at Intel and part of the team that brought PowerVia to fruition. In short, power and signals fade, requiring workarounds or simply dumping more power in.
