Intel is reportedly opening up key Atom processor technology to Rosaic, a chip startup led by Amarjit Gill, a longtime semiconductor entrepreneur with past ties to Intel CEO Lip-Bu Tan. The move highlights Intel’s broader effort to reposition itself in a rapidly changing chip market shaped by artificial intelligence, custom silicon, and renewed demand for efficient CPU designs.
According to the report, Intel is providing Rosaic with register-transfer level code, commonly known as RTL, for its Atom processor technology. RTL is a low-level hardware design description that defines how data moves through a processor’s registers and logic blocks. In practical terms, access to this type of technology could give Rosaic a much deeper foundation for building customized chips based on Intel’s established low-power processor architecture.
Intel Atom chips have long been designed for power-efficient computing. Over the years, they have been used in products and markets where energy consumption, compact design, and cost efficiency matter. While Atom processors were once closely associated with mobile and lightweight computing ambitions, Intel has more recently positioned the lineup toward server, networking, edge computing, and embedded applications.
The latest generation of Atom chips reflects that shift. Intel has refreshed its Atom P-Series and expanded its Atom X Series, targeting use cases where low power draw and reliable performance are essential. These chips are especially relevant for networking equipment, infrastructure hardware, and specialized computing systems that need efficient processing rather than the highest possible raw performance.
Rosaic’s connection to Intel’s leadership adds another layer of interest to the deal. The startup is led by Amarjit Gill, who has previously worked alongside Lip-Bu Tan in semiconductor investment and chip development ventures. Gill was involved with Tan in backing Nuvia, a high-performance chip company, and also worked with him in the creation of Rivos, a company focused on RISC-V processor technology.
Lip-Bu Tan became Intel CEO in 2025 and has been leading a major turnaround effort at the company. Intel has faced intense pressure in recent years from rivals in both chip design and manufacturing, particularly as the artificial intelligence boom has reshaped the semiconductor industry. Under Tan, Intel is working to strengthen its foundry business while also finding new ways to make its CPU technology relevant in the age of AI.
The timing is important. Much of the recent excitement in AI computing has centered on GPUs and specialized accelerators, which are widely used for training and running large AI models. However, CPUs remain critical for many parts of the computing stack, including data management, orchestration, inference workloads, and enterprise AI systems. Intel appears to be betting that the next phase of AI growth, including agentic AI and distributed intelligent systems, will create fresh demand for strong, efficient CPU technology.
By sharing Atom technology with Rosaic, Intel may be exploring a more flexible approach to chip innovation. Rather than only selling finished processors, Intel can potentially allow selected partners or startups to develop custom designs using Intel intellectual property. This could help Intel extend the reach of its architecture into specialized markets where custom silicon is becoming increasingly important.
The broader x86 processor market remains dominated by Intel and AMD, which are the two largest designers of chips based on the x86 architecture. Outside the United States, companies such as Shanghai Zhaoxin Semiconductor and Hygon Information Technology serve China’s domestic market for x86-based computing solutions. Still, the rise of Arm-based chips and RISC-V alternatives has increased competitive pressure, especially in power-efficient and custom processor designs.
That is where Atom could become strategically useful. While Intel’s high-performance Core and Xeon processors receive much of the attention, Atom offers a different advantage: efficiency. In modern computing environments, especially at the edge and in networking systems, the ability to process data with lower energy usage can be just as important as maximum performance.
For Rosaic, gaining access to Intel’s Atom RTL could significantly accelerate development. Designing a processor from scratch is expensive, technically demanding, and time-consuming. Starting with proven processor technology may allow the startup to focus on customization, optimization, and specialized features for its target markets.
For Intel, the arrangement could be a sign of a more open and partnership-driven strategy under Tan’s leadership. As the company tries to regain momentum, collaboration with startups and custom chip developers may help it stay competitive in markets that are moving faster than traditional product cycles.
The reported deal also reflects a wider shift in the semiconductor industry. Demand for AI hardware is not limited to giant data center GPUs. Companies increasingly need customized chips for cloud infrastructure, edge AI, networking, robotics, autonomous systems, and enterprise automation. Efficient CPUs, specialized accelerators, and hybrid chip designs are all likely to play important roles.
Intel’s decision to share Atom processor technology with Rosaic could therefore be more than a simple licensing or technology-transfer move. It may point to how Intel wants to participate in the next wave of AI and custom silicon: by combining its deep processor intellectual property with faster-moving external innovators.
If successful, the strategy could help Intel expand the relevance of its x86 technology, strengthen its position in low-power computing, and create new opportunities in markets where custom chips are becoming essential. For Rosaic, it provides a valuable technical foundation. For Intel, it may be another step in a larger comeback plan focused on AI, foundry services, and the future of efficient computing.
