Strategic Deep-Dive

iders (CSPs) and GPU manufacturers. Furthermore, the integration of HBM4 into the P4 roadmap highlights a shift toward ‘customized memory’—a strategy where memory is co-designed with major logic players. From a technical standpoint, the HBM4 transition involves moving to a 12-layer and 16-layer vertical stacking architecture, which significantly increases manufacturing complexity.

By fast-tracking P4, Samsung aims to secure the ’learning curve’ advantage early, ensuring higher yields before its competitors can reach similar scale. Additionally, this move addresses the ‘bottleneck’ concerns expressed by AI hardware architects who fear that GPU performance gains will be nullified by insufficient memory bandw
