Intel Reportedly Finalizing Deal with Samsung for 8nm Chipset Production

Intel is reportedly in the final stages of negotiations with Samsung Electronics to manufacture its next-generation Platform Controller Hub (PCH) chips, a move that would break the company's long-standing reliance on its internal fabrication for these specific components. According to reports from The Korea Economic Daily on December 16, 2025, the potential deal would utilize Samsung’s mature 8nm process node, with mass production scheduled for early 2026.

This development signals a crucial evolution in the relationship between two of the world's largest chipmakers. While they remain fierce rivals in the foundry business, Intel appears to be deepening its collaboration with Samsung for non-core components. This strategic pivot aligns with Intel's broader efforts to optimize its fabrication network by outsourcing "non-leading-edge" silicon, allowing its own fabs to concentrate on advanced process nodes like 18A.

The Shift to 8nm: A Generational Leap in Density

The move to Samsung’s 8nm node represents a massive density boost for Intel’s chipset architecture. Historically, Intel has relied on Samsung's 14nm process for its PCH chips—the components that manage data flow between the processor and peripherals like USB ports, networking, and storage—since the 500/600-series chipset era.

Transitioning to 8nm is not a minor revision; it is a multi-generational jump. Samsung’s 8nm process (8LPP) is a derivative of its 10nm node and offers roughly double the transistor density of the 14nm standard (approximately 61 MTr/mm² versus roughly 30-37 MTr/mm²). This architectural shrink provides significant benefits:

Major Area Scaling: The die size can be reduced by up to 40-50%, freeing up critical motherboard real estate for other components or allowing for smaller form factors.
Enhanced Power Efficiency: Moving from 14nm to 8nm typically yields power consumption reductions in the range of 30-40% at the same performance level, a critical factor for battery life in laptops.
Improved I/O Performance: The denser logic allows for more complex I/O controllers and faster switching speeds, ensuring smoother communication between the CPU and modern peripherals.

According to Bloomberg Intelligence estimates from earlier this week, outsourcing these components could reduce Intel's fabrication costs by 15-20%. This cost-saving measure is vital as Intel navigates a challenging financial landscape and aggressive competition from rivals like AMD and NVIDIA.

Strategic Implications for Samsung and Global Supply Chains

For Samsung Electronics, securing this order would be a major victory for its foundry division, which has been aggressively courting global clients to fill capacity on its mature nodes. While the company competes directly with TSMC for cutting-edge 3nm and 2nm orders, its 8nm technology has emerged as a "sweet spot" for high-volume, cost-sensitive components that do not require extreme ultraviolet (EUV) lithography for every layer.

Production is expected to take place at Samsung’s facilities in South Korea, likely in Hwaseong or Pyeongtaek. With a capacity of roughly 50,000 to 60,000 wafers per month for this specific node, Samsung is well-positioned to handle the volume required for Intel’s global PCH supply.

The agreement underscores the increasing necessity of "co-opetition" in the chip industry. Intel’s "IDM 2.0" strategy explicitly calls for leveraging external foundries to ensure supply chain resilience and cost competitiveness. By offloading PCH production to Samsung, Intel frees up its domestic capacity for high-margin, cutting-edge CPU production.

Furthermore, this deal reinforces the relevance of mature nodes. While the industry fixates on the race to 2nm and beyond, mature processes like 8nm remain the workhorses of the digital world, powering everything from automotive microcontrollers to PC chipsets.

If finalized, this partnership serves as a diversification strategy against geopolitical risks. It ensures that critical PC components have a reliable manufacturing base outside of Taiwan and China, strengthening South Korea’s position in the global semiconductor ecosystem and stabilizing supply chains for the broader PC market.
