Since the launch of OpenAI’s ChatGPT, AI development has largely been driven by GPUs, although CPUs still play a vital role, particularly in AI inferencing tasks. While GPUs, notably those from Nvidia, dominate training large models due to their parallel processing capabilities, they also present challenges related to cost and power consumption. For instance, advanced GPUs such as Nvidia’s H100 can be particularly expensive, and their energy demands are considerable.

In this context, CPUs offer a cost-effective and power-efficient alternative, particularly for smaller AI models. They provide the necessary flexibility and efficiency for a range of tasks, including data preparation and system memory management. They are essential in facilitating high system utilization in AI workloads, ensuring performance maximization without significant cost increases.

The role of CPUs becomes even more important as they take on new responsibilities in GPU-accelerated systems. They manage data transmission to GPUs and support mixed workloads in accelerated environments. With Intel’s new generation of Xeon processors, features such as enhanced core counts, greater I/O bandwidth, and advanced memory support highlight the central role CPUs play in meeting the complex demands of AI workloads.

Intel’s Xeon 6 series is designed with robust performance and efficiency in mind, offering improved I/O capabilities, increased core counts, and support for high-performance tasks like AI model training and inferencing. These processors enhance AI and mixed workload performance while addressing power efficiency, making them optimal for host roles in AI systems.

As AI continues to evolve, the symbiotic relationship between CPUs and GPUs becomes more apparent. Intel’s latest offerings reflect this shift, positioning CPUs as indispensable players in the ongoing enhancement of AI system performance.
