Atificial intelligence, a paradox has emerged: as AI becomes more powerful and broadens the scope of what's achievable, it simultaneously introduces an escalating level of complexity and coordination overhead. Without proper alignment and harnessing, these vast potential risks can descend into chaos. However, according to Deanna Berger (IBM Technology Z Subsystem Architect), AI cards are quickly becoming a fundamental component for modern AI integration, offering a strategic solution for organizations to simplify the intricate AI ecosystem and fully leverage the power of agentic AI across their IT systems, data centers, and platforms. These tools are reshaping workflows to optimize everything from fraud detection to regulatory compliance, pointing towards a future of profound AI innovation.
At its core, an AI card is a physical piece of hardware specifically designed to accelerate AI processes. Deanna Berger explains that these cards can vary in form, from a tiny piece of silicon integrated directly into a processor chip (on-die) to larger components mounted on a system board, such as FPGAs or GPUs, or even physical cards attached to a system via an industry-standard PCIe port. While the term "AI card" generally refers to anything used to accelerate AI, it's crucial to distinguish it from an AI accelerator card. An AI accelerator card is a more specialized entity; its microarchitecture and chip are purpose-designed and fabricated to perform acceleration for one or more specific AI tasks. Accelerators are, therefore, a very powerful subset within the broader AI card space. This distinction is critical because it directly impacts efficiency. In AI, efficiency is a multifaceted metric encompassing the accuracy of the result, the speed at which it's returned, and the power consumption and sustainability impacts. While a general-purpose card might achieve fair efficiency in some use cases, it won't be as optimal as an accelerator specifically designed and optimized for tasks like training, deep inferencing, or fine-tuning.
Illustrating this, Deanna Berger notes that GPUs (Graphics Processing Units) are common general-purpose cards used for AI due to the overlap between linear mathematics in graphics processing and AI workloads, despite their original design for graphics. FPGAs also offer flexibility as general-purpose hardware. In contrast, specific AI accelerators include Tensor Processing Units (TPUs), Neural Processing Units (NPUs)—designed to mimic brain-like neural networks—and custom-designed ASICs (Application-Specific Integrated Circuits), all tailored for specialized AI functions. The existence of such a wide array of cards is driven by the vast variability of AI use cases. While some general-purpose AI cards suffice, many applications demand optimized hardware for effectiveness, real-time transaction processing, or the fine-tuning required in fields like medical research. The complexity truly escalates when enterprise-level goals necessitate multiple AI tasks running in parallel, requiring the right combination of models and cards for each task. There isn't a simple one-to-one mapping between a use case and a single model, nor between a model and the specific card it will run optimally on. A single use case might leverage multiple models, each potentially running on different cards chosen for their specific optimizations or availability.

Deanna Berger provides a compelling example with fraud detection, where a traditional machine learning/deep learning (ML/DL) model might be combined with a generative AI (Gen AI) model to optimize for inference accuracy and speed. For the traditional ML/DL model, which needs to process an in-flight transaction with extreme rapidity, an AI card physically located on the same processor chip (on-die) where the workload runs would be ideal. The significantly larger Gen AI model, benefiting from proximity to memory and caches, might best leverage a PCIe-attached card. This strategic placement allows for human-undetectable response times, ensuring user satisfaction despite the underlying complexity of using multiple models. Other use cases similarly dictate specific card choices: operational adaptability, such as quickly reacting to transaction spikes or data center temperature changes, benefits from on-system or on-die AI accelerators for rapid response. For analytics, which involves large datasets for future decision-making without real-time constraints, a more general-purpose card on a system board or even a remote server might be suitable. Model training can often be performed elsewhere before deployment.
However, the most complex scenarios, like regulatory compliance, highlight the limitations of conventional approaches. Such tasks are highly regulated, nuanced, and subject to constant changes, demanding multiple models—perhaps a Retrieval Augmented Generation (RAG) model for deciphering updates, a Natural Language Processing (NLP) or Large Language Model (LLM) for understanding and communicating rules, and a predictive ML/DL model to foresee compliance issues. While a custom-designed ASIC, optimized for language processing and predictive models, could simplify this to a single "compliance card," building a custom ASIC for every unique AI use case is impractical given the sheer number of possibilities.
This is precisely where Agentic AI becomes profoundly powerful and helpful. As Deanna Berger explains, Agentic AI involves virtual AI agents built in the virtual world, capable of autonomous decision-making and goal-directed behavior. These agents act as virtual assistants for infrastructure management, intelligently deciding which AI cards and models to employ. When presented with a problem, an AI agent can capture the input, understand the task, and then, based on available resources, determine the optimal models to use and where to deploy them. For instance, a compliance agent could rapidly send critical checks to an on-system card while routing less time-sensitive report generation to a remote server, all while optimizing task completion and managing resource load to avoid conflicts. This intelligent resource allocation ensures tasks are completed as soon as possible without overloading critical systems.
Ultimately, AI cards are not just accelerating AI; they are becoming a vital catalyst for the agentic AI paradigm. This ongoing shift, leveraging AI cards in conjunction with agentic AI to manage the complex logistics in the virtual world, is poised to redefine human-computer interaction for the better and unlock an almost infinite number of possibilities in the future of AI innovation.
