Intel granted startup RosaicLabs rare access to Atom processor RTL code, letting it design custom low-power chips using Intel’s x86 architecture. | Daily Reports Online
- Intel shared rare x86 chip design access with a brand-new startup
- RosaicLabs can now build custom processors using licensed Atom architecture
- Intel shifted its low-power strategy from Atom towards newer E-Core designs
Intel has given RosaicLabs access to part of its Atom processor technology in a rare move involving the company’s x86 intellectual property.
Reports from Reuters claim the agreement involves register-transfer level, or RTL, code that describes processor functions before they are converted into physical silicon during manufacturing.
Atom was designed for low-power computing, making the technology suitable for systems requiring efficient performance without high energy consumption or excessive heat generation.

Why Atom technology fits the reported agreement
Intel’s Atom processors have historically powered entry-level systems, networking equipment, embedded devices, and other products where power efficiency matters more than maximum performance.
The processor family runs on the x86 architecture and was developed to provide Intel-based computing for smaller and lower-power devices.
RosaicLabs is expected to receive RTL code for Atom technology, which could allow it to create custom processor designs using Intel’s existing architecture.
A veteran semiconductor executive said such access provides “comprehensive exposure” to Intel’s intellectual property, giving customers the ability to develop their own silicon based on licensed designs.
Providing Rosaic access to Atom technology is unusual because Intel has traditionally kept key parts of its x86 intellectual property under tighter control rather than widely licensing processor designs.
However, Intel’s Atom portfolio has become smaller as the company shifted its low-power processor strategy toward E-Cores, which succeeded Atom-based designs in newer products.
E-Cores use newer microarchitectures such as Gracemont, meaning Intel may view selected Atom technology as suitable for external licensing while keeping its latest processor designs within its own roadmap.
The exact Atom technology Rosaic will receive remains unclear, although the startup could potentially gain access to Tremont, one of Intel’s final Atom microarchitectures.
Tremont was used in products such as Elkhart Lake and Jasper Lake, which supported embedded systems, low-power laptops, and Chromebooks.
Rosaic has some connections with Intel
Rosaic is a startup incorporated in Delaware in May 2026, but details about the company remain limited beyond its reported agreement with Intel over Atom processor technology.
An amended corporate filing dated July 24 shows the company can pursue a $10 million seed funding round while approving capital expenditures below $5 million without investor or board approval.
The startup’s founding team reportedly includes former Rivos employees, linking Rosaic with a semiconductor company that Meta acquired for roughly $2 billion last year.
Rosaic’s connection with Intel also extends to its leadership because chief executive Amarjit Gill previously helped assemble Rivos’ founding team alongside Intel chief executive Lip-Bu Tan, who chaired that company.
Gill and Tan also shared an investment history, making early bets on Nuvia before Qualcomm acquired the startup, adding another link between Rosaic’s leadership and Intel’s current chief executive.
These professional relationships have drawn attention to Rosaic, although neither company has publicly explained whether they influenced Intel’s decision to share Atom processor technology.
After the announcement, Intel shares rose 12%, although no evidence directly linked those market gains with the reported licensing arrangement.
This agreement suggests Intel may see continued value in Atom’s low-power x86 design, but its broader intentions remain uncertain until Rosaic reveals its future processor plans.
