Samsung has unveiled a mockup of its HBM5 memory at Computex 2026, featuring a new cooling technology called Heat Path Block (HPB). This development places Samsung in direct thermal competition with SK hynix, which recently announced its own iHBM cooling design. Both companies are focusing on managing heat generated at the die-to-die interface, crucial for the increasing power demands of AI systems. Samsung plans to manufacture HBM5 using its 2nm process, aiming for mass production by 2028. AI
