The Infrastructure Thesis

  Advanced chip design used to focus almost entirely on the processor itself. Smaller transistors, faster clocks, and more efficient architectures drove most performance gains. But as semiconductor technology approaches physical limits, another layer of innovation has become increasingly important. Packaging. In modern AI systems, performance depends not only on the chip but also on how different components are connected together. GPUs, memory stacks, and interconnects must operate as a tightly integrated system. This is where advanced packaging comes in. Advanced packaging technologies allow multiple chips and memory stacks to be combined into a single high-performance module. Instead of relying on a single monolithic chip, designers can assemble complex systems using several specialized components. For example, modern AI accelerators often combine powerful GPUs with multiple stacks of high-bandwidth memory. These components must be placed extremely clo...
