Intel's architectural pivot from monolithic silicon to disaggregated chiplets

Science · Published 1 November 2026 Swipe more like this →

In short: For decades, Intel built processors as single pieces of silicon. That era ended with the Meteor Lake generation. By moving to a multi-chip module design, Intel fundamentally changed how it scales performance and efficiency, marking a major shift in modern semiconductor engineering.

Intel's transition to chiplet architecture began significantly with the Meteor Lake generation, which was the first mobile generation to utilize this multi-chip module approach. This move represents a departure from monolithic silicon designs, where all components are integrated onto one piece of material. By disaggregating the design, manufacturers can optimize different parts of the processor independently. This architectural shift is central to the Core Series 2, released on October 24, 2024. This shift allows for more flexible manufacturing processes across different dies. The Core Series 2 succeeded the previous Meteor Lake architecture.

While its predecessor, Meteor Lake, was limited primarily to mobile releases, the successor Arrow Lake includes both desktop and mobile processors using this disaggregated MCM (Multi-Chip Module) design. Notably, these newer architectures—specifically Arrow Lake and Lunar Lake—do not support Hyper-Threading, a significant technical distinction from previous generations. Arrow Lake-U specifically utilizes refreshed silicon from the Intel 3 node. These newer parts are designed to balance power and performance in various form factors.

The branding landscape also underwent a major overhaul in June 2023. Intel moved away from the traditional 'Core i3/i5/i7/i9' naming convention to a dual-brand system: Core and Core Ultra. The Core brand is designated for value-oriented, everyday processors (including refreshed Raptor Lake products), while Core Ultra is reserved for premium offerings. This hierarchy helps manage a complex product lineup that spans from 4-bit 4004 chips dating back to 1971 to high-end modern infrastructure like Clearwater Forest, which supports up to 1.5 TB of DDR5 RAM. Clearwater Forest is a specific example of this high-end infrastructure, supporting ECC memory for data centers. Furthermore, some models remain soldered directly to motherboards using the BGA1792 socket.
