Samsung plans to adopt a 2nm base die in the HBM5 generation, with an expected operating speed increase of over 50% compared to HBM4E. This base die supports higher-density through-silicon vias, significantly improving performance and energy efficiency. Previously, Samsung's HBM4 and HBM4E both utilized 4nm base dies, with HBM4E achieving high-speed operation at 14+ Gbps through the application of high-density, ultra-high-performance devices, while also reducing power consumption and improving heat dissipation paths by optimizing metal layer arrangements.
