The Memory Wall in AI: HBM3e Bandwidth Limits, Chiplets, and PIM Concepts
The Growing Chasm Between Compute and Memory The artificial intelligence revolution is facing an unexpected adversary: physics. As large language models grow exponentially—doubling in parameter count every 24 months—memory bandwidth improves at a meager 1.6× over the same period, while floating-point performance increases only 3× . This widening gap between computational capability and data transfer speed … Read more
