Intel Nova Lake CPUs: Potential “X3D-Like” Performance with 18A-PT Process and Foveros Direct 3D Packaging

The PC consumer market has been eagerly anticipating an “X3D-like”technology from Intel, and the upcoming Nova Lake desktop CPU series may finally deliver on that expectation.

Intel’s Progress Towards “X3D-Like”CPUs and Future Implementation

Intel is currently navigating challenges in the desktop CPU landscape, especially after an underwhelming reception of its latest series, including the Core Ultra 200S processors. Many users have been deterred by the lackluster performance and have begun opting for AMD alternatives. However, with the introduction of Nova Lake, a shift in the tide may be on the horizon, particularly following announcements made during the recent Intel Direct Connect 2025 event which hinted at an impending “X3D”implementation.

Historically, Intel has not dismissed the idea of creating a “3D V-Cache”technology. Former CEO Pat Gelsinger hinted at using their proprietary approaches, including Foveros and EMIB, to develop such processors. The company appears eager to expand its offerings in this area. Recently, Intel’s Tech Communications Manager indicated a strategic focus on enhancing cache integration within server products, while leaving the door open for consumer applications in the future.

At the Intel Direct Connect 2025 event, the introduction of the Intel 18A-PT process node highlighted advancements towards next-generation 3D Integrated Circuit (3DIC) designs. With an enhanced back-metal design and through-silicon vias (TSVs), Intel aims for high-density, high-bandwidth vertical chiplet stacking.

By utilizing Foveros Direct 3D hybrid bonding, Intel can effectively compete with TSMC’s System on Integrated Chips (SoIC) approach. With a bonding pitch below 5μm, this technology promises to outmatch TSMC’s 9μm SoIC-X, potentially giving Intel a considerable advantage over AMD’s current X3D offerings. Notably, AMD’s “3D-V Cache”has significantly contributed to its success in the consumer CPU segment, with many users expressing satisfaction with the additional L3 cache.

It remains plausible that Intel will assess the performance of its Clearwater Forest Xeon CPUs before fully committing to the Foveros Direct 3D stacking technology for consumer CPUs. Nonetheless, if Intel prioritizes and invests in this innovation, the company stands poised to reclaim prominent market visibility.
