What are the key AI chip trends that have been established for a long time and continue to shape the industry today?

Domain-specific architectures (DSAs) represent the most enduring trend, delivering 2-10x better performance-per-watt compared to general-purpose CPUs.

GPUs maintain dominance for parallel workloads, but specialized processors like NPUs, TPUs, and task-specific ASICs are capturing increasing market share. This shift began with NVIDIA's CUDA-enabled GPUs in the 2010s and accelerated with Google's first TPU deployment in 2016. The transition reflects the fundamental mismatch between CPU architectures designed for sequential processing and AI workloads requiring massive parallel computation.

Memory-centric design has become equally critical, with High-Bandwidth Memory (HBM2/3) integration directly on-package to address the "memory wall" that limits large model performance. On-chip SRAM caches and scratch-pads minimize costly off-chip data transfers, while HBM3e modules now reach 6 TB/s bandwidth on latest accelerators like NVIDIA's H200.

Energy efficiency constraints drive every design decision, as power budgets cap both data-center and edge deployments. Low-precision formats (INT8, BF16) and dynamic voltage-frequency scaling have become standard, while liquid and immersion cooling enable sustained high throughput in data centers. Heterogeneous system-on-chip (SoC) designs combining CPU cores, DSPs, and accelerators on single dies offer optimal performance-per-watt for specific workloads.
