A Collection of Keywords to Understand AI Semiconductor and HBM Trends

An overview of key trends driving the semiconductor industry today, including GPU, AI accelerators, HBM, CoWoS, chiplets, and data center power.

The most significant trend in the semiconductor industry right now is AI. As investments in generative AI and data centers increase, GPUs, AI accelerators, HBM, advanced packaging, power efficiency, and networking chips are all gaining attention. However, simply saying 'GPUs are great' is not enough to understand AI semiconductors. The actual systems require an interconnection between computation chips, memory, packaging, foundry, power, cooling, and software. This list summarizes key keywords that are helpful for understanding the flows of AI semiconductors and HBM.

GPU

The GPU is at the center of the AI semiconductor flow. Originally developed for graphic processing, its ability to handle vast amounts of calculations in parallel makes it ideal for AI training and inference. As generative AI models increase in size, the demand for GPUs has risen, and how GPU clusters are constructed in data centers has become essential. However, having a GPU alone does not complete an AI system. HBM, networking, power, cooling, software, and packaging all need to be in place to achieve actual performance. Therefore, it's beneficial to view GPU news in connection with the entire ecosystem.

AI Accelerator

AI accelerators are semiconductors designed to process AI computations faster and more efficiently. While GPUs are representative, there is a growing trend of ASIC-type accelerators tailored to specific models or services. Cloud companies develop their chips for reasons including cost, power efficiency, supply chain stability, and service optimization. When evaluating AI accelerators, it's important to consider not just computational performance but also memory bandwidth, software support, data center application scale, and production partners. Even a good chip can be limited in its adoption without a compatible ecosystem and supply.

HBM

HBM stands for High Bandwidth Memory and is a crucial memory type in AI semiconductors. AI models need to read and write large amounts of data quickly, so even the fastest computation chip will be bottlenecked by inadequate memory bandwidth. HBM stacks multiple DRAM dies vertically to provide high bandwidth and is integrated close to GPUs or AI accelerators. When examining the HBM industry, it’s important to check for generations, capacities, bandwidths, customer certifications, yields, and packaging availability. Strong demand must be met with supply and certification for sales to materialize.

CoWoS

CoWoS is a high-tech packaging keyword that frequently appears in the AI semiconductor flow. TSMC describes CoWoS as a packaging technology suitable for AI and supercomputing applications, allowing for high-density integration of logic chips and HBM stacks on a silicon interposer. Because data movement between computation chips and memory is critical in AI chips, such packaging technology can significantly influence performance and supply. Thus, when discussing AI semiconductor bottlenecks, it’s important to mention packaging production capabilities like CoWoS along with foundry processes.

Chiplet

Chiplets are a method of building a single large chip by dividing multiple functional blocks into smaller chips that are connected during the packaging stage. As advanced process costs rise and chip sizes grow, chiplet designs become attractive options in terms of yield and cost. In AI and HPC chips, structures combining compute chiplets, I/O chiplets, and memory interfaces are becoming increasingly important. However, for chiplets to succeed, connection speeds, latency, power, packaging, and design standards need to align. Chiplets signal the importance of both design and packaging working together.

AI Data Center Power

An AI data center isn't just about fitting in a lot of GPUs and AI accelerators. High-performance semiconductors consume significant power and generate heat, necessitating power supply, cooling, rack design, and network infrastructure. Chips with good power efficiency offer substantial advantages in operating costs and data center scalability. When observing AI semiconductor news, it's beneficial to consider not just chip shipments but also power infrastructure, cooling technologies, and data center investment plans to better understand industry bottlenecks. Power may seem like an external issue to semiconductors, but it can actually limit real demand.

Inference Semiconductors

AI semiconductors can be thought of in terms of training and inference. Training is the process of creating large-scale models, while inference is the execution stage of real services that answer user questions or generate images. As service usage increases, inference costs and power efficiency become more critical. Thus, there’s a rise in not only GPUs but also AI accelerators specialized for inference and self-developed chips. When considering inference semiconductors, factors such as service cost per use, latency, software compatibility, and large-scale deployment potential may be more important than peak performance.

Networks and Interconnects

Networking and Interconnect

In AI data centers, the structure where numerous chips work together is more important than a single chip. If data movement between GPUs and servers is slow, overall training and inference efficiency may decrease. Hence, high-speed networks, switches, interconnects, optical communications, and internal package connection technologies are drawing attention. When understanding AI semiconductors, it’s essential to look beyond just computation chips and memory, considering the technologies connecting chips to chips and servers to servers. Bottlenecks in data movement impact performance, power efficiency, and data center costs.

The flow of AI semiconductors is rapidly changing, and overheated expectations mix in as well. Even with increasing HBM demand, memory prices, customer certification, packaging production capacity, foundry processes, and data center power constraints all need to align for continued performance. Different companies benefit from AI in varying ways; some design GPUs, others produce HBM, and some handle foundry and packaging. This list is a summary of keywords for understanding industrial trends, and it’s best to check official earnings reports and disclosures for the latest figures and investment decisions.
