Introduction
South Korea’s memory chip giant, SK Hynix, has landed a significant deal with Broadcom, a leading US semiconductor company, to supply high-bandwidth memory (HBM). This collaboration underscores the growing demand for advanced memory solutions in artificial intelligence (AI) computing. The deal positions Broadcom as a formidable challenger to Nvidia, the current leader in the AI chip market.
The order is expected to elevate SK Hynix’s market dominance while amplifying Broadcom’s competitive edge in the AI sector. Here’s a closer look at what this development means for the tech industry.
Key Highlights
- Massive HBM Order: SK Hynix will supply Broadcom with HBM for AI computing chips used by a leading Big Tech firm.
- Strategic Move for Broadcom: Broadcom aims to challenge Nvidia with AI chips tailored for specific applications, leveraging NPUs (neural processing units).
- Production Expansion: SK Hynix plans to increase its 1b DRAM production capacity to meet this new demand.
- HBM Market Leadership: With this deal, SK Hynix solidifies its position as the largest HBM supplier globally.
- AI Market Impact: The partnership reflects the rapid evolution of AI chip designs, emphasizing efficiency and performance.
Broadcom’s Bold Move into AI Chips
Broadcom’s collaboration with SK Hynix marks its serious foray into the AI chip market. Unlike Nvidia, which dominates with its general-purpose GPUs (graphics processing units), Broadcom is focusing on NPUs designed for specialized tasks. NPUs are known for their efficiency in power, cost, and speed, making them ideal for next-generation AI workloads.
Broadcom has reportedly been working with major cloud service providers, including Google, Meta, and ByteDance, to develop cutting-edge AI chips. Unconfirmed reports suggest partnerships with Apple and OpenAI are also in progress. These collaborations could disrupt the AI chip landscape, which Nvidia has long dominated.

SK Hynix: Expanding Production Capacity
SK Hynix has been ramping up its production to meet the surging demand for HBM, particularly its HBM3E version.
The company’s 1b DRAM is the core of its HBMs. The new Broadcom deal will increase production capacity from 140,000-150,000 wafers to 160,000-170,000 wafers in 2024.
This boost may delay installing equipment for 1c DRAM, which will replace 1b DRAM. The company is focusing on immediate demand instead. SK Hynix’s HBM powers Nvidia’s AI accelerators. It will now also use it, strengthening the South Korean firm’s market position.

Why HBM Matters ?
HBM, or High Bandwidth Memory, is crucial for AI applications due to its ability to overcome the “memory wall” bottleneck.
- Massive Data Demands: AI models, especially deep learning models, require enormous amounts of data for training and inference. HBM’s high bandwidth allows for rapid data transfer between the processor and memory, enabling faster processing of these large datasets.
- Reduced Latency: HBM significantly reduces the time it takes to access data, minimizing delays in computation. This is critical for real-time AI applications where quick responses are essential
- Improved Energy Efficiency: By reducing the amount of data that needs to be transferred, HBM can help lower power consumption, making AI systems more energy-efficient.
Smaller Form Factor: HBM’s 3D stacked design allows for higher memory density in a smaller physical space, making it ideal for compact AI systems.
In essence, HBM empowers AI systems to handle the ever-increasing demands of complex AI tasks, enabling faster training, more efficient inference, and ultimately, more powerful and responsive AI applications.
Broadcom’s AI Strategy
Broadcom’s AI accelerator chips use NPUs. These prioritize specific tasks over GPUs’ general-purpose capabilities. NPUs cost less and consume less energy, offering a strategic advantage.
Broadcom recently partnered with three major cloud providers. These are believed to be Google, Meta, and ByteDance. The company’s market valuation has exceeded 1 trillion won due to strong AI chip growth projections.

Growing Importance of HBM in AI
HBM is essential for AI chips due to fast data transfer and low power use. Complex AI models require efficient memory solutions like HBM.
In Q3 2024, SK Hynix reported that HBM contributed 40% of its DRAM revenue. This share will likely grow. Demand for HBM3E chips has exceeded expectations and will benefit from the Broadcom deal.
Implications for the AI Chip Market
- Increased Competition: Broadcom’s NPU chips could challenge Nvidia’s AI accelerator dominance.
- HBM Demand Growth: SK Hynix’s HBM supply will play a crucial role in AI’s development.
- Shift in Chip Design: Companies are shifting toward application-specific chips like NPUs.
- Economic Impact: The partnership will drive revenue for SK Hynix and boost Broadcom’s valuation.
- Tech Innovation: Collaboration underscores rapid advances in AI memory and chip technologies.
Conclusion
The SK Hynix-Broadcom partnership reflects the close link between memory and processors in AI. HBM’s speed and Broadcom’s tailored chip designs position both firms to lead AI computing. Broadcom could challenge Nvidia in the AI market through this collaboration. This partnership could reshape industry competition and speed up AI hardware innovation.
