  • Process – Intel 7 is in production and shipping in volume with the launch of 12th Gen Intel® Core™ processors and additional products coming in 2022. Intel 4, our implementation of extreme ultraviolet (EUV) lithography, will be manufacturing-ready in the second half of 2022. It delivers an approximate 20% increase in transistor performance per watt. Intel 3, with additional features, delivers a further 18% performance per watt and will be manufacturing-ready in the second half of 2023. Ushering in the Angstrom Era with RibbonFET and PowerVia, Intel 20A will deliver up to a 15% performance per watt improvement and will be manufacturing-ready in the first half of 2024. Intel 18A delivers an additional 10% improvement and will be manufacturing-ready in the second half of 2024.
  • Packaging  Our advanced packaging leadership gives designers options across thermals, power, high-speed signaling, and interconnect density, to maximize and co-optimize product performance. In 2022, Intel will ship leadership packaging technologies in Sapphire Rapids and Ponte Vecchio and start risk production on Meteor Lake. Foveros Omni and Foveros Direct, our advanced packaging technologies unveiled at Intel Accelerated in July 2021, will be manufacturing-ready in 2023.
  • Innovation  As Intel looks forward to technologies such as High-NA EUV, RibbonFET, PowerVia, and Foveros Omni and Direct, its leaders see no end to innovation and therefore no end to Moore’s Law. Intel remains undeterred in achieving its aspiration of delivering approximately 1 trillion transistors in a single device by the end of the decade.

Intel Client CPU Roadmap

Starting with the Intel Client CPU roadmap, the company has already launched its Alder Lake CPU lineup, and its follow-up, the 13th Gen Raptor Lake lineup is on track for launch later this year. For Raptor Lake, 24 cores and 32 threads have been confirmed (8+16). The blue team is also promising up to double-digit performance gains, enhanced overclocking support, a new AI M.2 support, and socket compatibility with the Alder Lake platform (LGA 1700/1800).

CCG Roadmap Updates – Building upon its leadership products today, Intel’s roadmap for next-generation client products includes:

  • Raptor Lake – Shipping in the second half of 2022, Raptor Lake will deliver up to double-digit performance increases compared with Alder Lake and come with enhanced overclocking features. Raptor Lake features up to 24 cores and 32 threads and is built on the Intel 7 process node with performance hybrid architecture. Raptor Lake will be socket-compatible with Alder Lake systems.
  • Meteor Lake and Arrow Lake – Meteor Lake will be built on Intel 4. Arrow Lake will be the first Intel product using Intel 20A tiles, as well as tiles made using an external process. These products will offer a huge step forward on XPU improvement, with integrated AI and tiled GPU architecture that offers discrete graphics-class performance. Meteor Lake will ship in 2023, and Arrow Lake will follow in 2024.
  • Lunar Lake and Beyond – Fueled by its IDM 2.0 strategy, Intel will be using both internal and external process nodes to deliver leadership products.

The next update to the Client CPU roadmap will come in the form of Meteor Lake which is scheduled for manufacturing on the 'Intel 4' process node in 2H 2022 and expected for launch in 2023. The 'Intel 4' node will deliver 20% performance per watt improvement and will be the first to use EUV technology, offering a significant increase in density over 'Intel 7' (10nm ESF). Intel will also be launching a follow-up to Meteor Lake in 2024 known as Arrow Lake.

Both Meteor and Arrow Lake CPUs will feature several different core IPs composed of Intel 4 (Meteor Lake), Intel 20A (Arrow Lake), and TSMC's N3 (Arc GPU / SOC) process node. What's particularly interesting is that starting Meteor Lake, the new CPUs will feature a Tiled-GPU design featuring Arc graphics architecture. Raja Koduri states that this 'tGPU' will be unlike anything previously done on client CPUs and will be different than discrete and integrated graphics designs.

Moving beyond 2024, Intel plans to offer a major overhaul to its Client platform with Lunar Lake and Nova Lake chips. These will likely be scheduled for 2025 and 2026 releases, respectively. The next-generation CPUs will come within a tiled-CPU architecture, featuring an MCM CPU, SOC, and GPU IPs integrated on the same package. Both Lunar Lake &  Nova Lake chips are expected to utilize the improved 18A node which will offer an additional 10% improvement in performance per watt and add more enhancements to the RibbonFET architecture. The manufacturing is scheduled for 1H 2024 for 20A and 2H 2024 for 18A chips. Other core IPs will be relying on external foundry nodes.

As you can see from the roadmap block diagrams, the next-gen Client platforms will be utilizing a fully-integrated MCM design, making use of several chiplets that will be integrated on the same CPU package. All in all, the following is the node-specific to the chiplet count we can expect on future client chips from team blue:

  • 4 - 3 Chiplet SOC
  • 20A - 4 Chiplet SOC
  • 18A - 5 Chiplet SOC

Intel Server CPU Roadmap

For servers, Intel plans to offer its first major architectural uplift in the form of Diamond Rapids which will be utilizing the 'Intel 3' process node. This node is expected to offer an 18% uplift in performance per watt and will utilize higher-performance libraries, optimized drive current, and metal stack. Intel states that it will have est wafers of their lead product (Xeon) running in their labs by the second half of 2022.

For the first time, Intel has also provided a first-look at its next-gen 18A powered Xeon CPU for the data center segment. This chip is shown with at least 17 tile blocks, 6 of which are CPU blocks.

The current Sapphire Rapids-SP Xeon CPUs feature 15 cores per CPU tile so an 18A chip with a similar core count will offer up to 90 cores though, by 2025, Intel would be offering more cores per CPU tile so we can definitely expect over 100 cores to match AMD's high-core count offerings in the server segment. Diamond Rapids on the '3' node is expected to offer up to 144 cores and 288 threads so 18A would definitely be offering a much higher core count. Intel has also confirmed that its Granite Rapid (P-Core) & Sierra Forest (E-Core) Xeon SKUs will be based on the 'Intel 3' process node.
