Samsung has unveiled a mockup of its HBM5 memory at Computex 2026, featuring a new Heat Path Block (HPB) cooling system. This development places Samsung in direct thermal management competition with SK hynix, which recently announced its own iHBM cooling design. Both companies are focusing on dissipating heat from the critical die-to-die interface to improve AI system performance and stability. Samsung plans to manufacture HBM5 using its 2nm process, aiming for mass production by 2028. AI
IMPACT Advanced cooling for HBM5 will enable more powerful AI processors by managing heat, potentially accelerating the development of more capable AI systems.
RANK_REASON This cluster reports on a new hardware technology (HBM5 memory with advanced cooling) from major industry players, indicating a significant development in AI infrastructure.
