Introduction
SK Hynix, a leading South Korean chipmaker, is set to produce the next-generation HBM4 chips using the advanced 3nm process, a shift from its earlier plan to use a 5nm process.
The HBM4 chips will be customized for clients like Nvidia, with deliveries expected by the second half of 2025.
Overview of HBM4 Development
- HBM4 Chips: SK Hynix will produce sixth-generation HBM4 chips for top clients like Nvidia, aiming for a late 2025 release.3nm Process: The 3nm process will increase performance by up to 30%, improving data transfer speed and reducing latency.TSMC Collaboration: SK Hynix will work with TSMC, a leader in semiconductor manufacturing, to produce the chips using the 3nm process.
Nvidia’s Request: Nvidia has requested SK Hynix to speed up production, asking for a six-month earlier delivery.
Market Dominance: SK Hynix leads the HBM market and plans to maintain its competitive edge, especially over rivals like Samsung.
Transition to 3nm Process
SK Hynix had initially planned to use a 5nm process for HBM4, but increasing demand for faster memory from major clients led to the decision to adopt a 3nm process.
The 3nm process will provide better efficiency and a 20-30% performance boost over the previous generation, enabling superior AI and gaming performance.
Prototype and Timeline
The first prototype of the 3nm-based HBM4 chip is expect to be unveiled by March 2025.
SK Hynix will begin full production and deliver the advanced HBM4 chips in the second half of 2025, with Nvidia among the first to receive them.
TSMC’s Key Role
TSMC, renowned for its 3nm chip production, will play a critical role in manufacturing the HBM4 chips.
This partnership ensures that SK Hynix can utilize the latest semiconductor technology, maintaining its lead in the high-performance memory market.

Nvidia’s Influence
Nvidia, a major client of SK Hynix, has played a significant role in the acceleration of HBM4 development.
Nvidia’s CEO, Jensen Huang, requested a six-month earlier supply of the 12-layer HBM4 chips. This highlights the growing demand for high-bandwidth memory in AI applications.
Geopolitical Factors
SK Hynix’s decision also comes amid rising geopolitical tensions, especially between the U.S. and China.
With U.S. semiconductor export restrictions on China, SK Hynix is focusing more on American tech giants like Nvidia, Google, and Microsoft, reducing reliance on China.
Competing with Samsung
Samsung Electronics is working on sixth-generation HBM but plans to use a 4nm process.
SK Hynix’s 3nm process offers higher performance and efficiency, giving it an edge over competitors.
General-Use HBM4 for Broader Applications
SK Hynix will produce general-use HBM4 and HBM4E variants using a 12nm process.
These cost-effective chips will serve industries like automotive and data centers.
