Beyond a single die
Training and serving demanding AI workloads require enormous amounts of data movement. Bringing memory and compute closer together can matter as much as adding raw arithmetic capability.
Advanced packaging combines components in ways designed to shorten communication paths and increase bandwidth.
Manufacturing is a system
Performance depends on chip design, memory supply, interconnects, cooling and software. A breakthrough in one area can be constrained by another.
This makes supply chains and manufacturing capacity central to competition.
What to watch
Rather than focus on headline processor specifications alone, buyers should ask about system-level throughput, energy efficiency, availability and workload compatibility.
The most important AI chip may be the one that fits best into an efficient complete system.
