The increasing cost and scarcity of memory, particularly High Bandwidth Memory (HBM), are becoming a significant bottleneck for hyperscalers, impacting hardware design and potentially slowing down device upgrades. This 'memory wall' is a critical factor in current AI infrastructure development.
Impact: High. This constraint forces a re-evaluation of hardware design, pushing for more efficient memory utilization and potentially impacting the pace of AI advancement. The sheer scale of hyperscaler CapEx on memory underscores its critical role.
