Nano Banana Defining The Shift The semiconductor industry is no longer driven by a single scaling vector. As traditional transistor scaling slows, performance, efficiency, and system capability are now achieved through three distinct but interconnected approaches: Scale-Up, Scale-Out, and Scale-Across. Together, they form a scaling trilemma in which each path offers advantages but imposes constraints. Scale-Up focuses on maximizing capability within a single silicon boundary by increasing transistor density, integrating more functionality, and leveraging advanced nodes. This approach delivers high performance but faces growing challenges in yield, power density, and cost. Scale-Out expands capability by distributing workloads across multiple chips or systems. It underpins modern cloud and AI infrastructure but introduces bottlenecks related to interconnect bandwidth, latency, and data movement. Scale-Across enables scaling through heterogeneous integration, combining […]
