NVIDIA is launching powerful CPUs like the RTX Spark not just to compete with Apple, but because the primary AI workload is shifting. While GPUs dominate AI training, powerful CPUs are becoming essential for running agentic tools and inference, marking a resurgence for the CPU in the AI hardware landscape.

While GPUs dominate AI hardware discussions, the proliferation of AI agents is causing a significant, often overlooked, CPU shortage. Agents rely on CPUs for web queries, data processing, and other tasks needed to feed GPUs, straining existing infrastructure and driving new demand for companies like Arm and Intel.

The rise of agentic AI and reinforcement learning is increasing the need for powerful CPUs located near GPUs. Cloud provider Nebius notes CPU requirements can be a high multiple of the GPU count, fueling a new demand cycle.

While GPUs are key for model training, the next AI wave of autonomous agents relies more on CPUs. The task of controlling and orchestrating multiple agents and tool calls is fundamentally a CPU-based process. This is creating a new hardware bottleneck and shifting focus to CPU manufacturers.

The current AI boom focuses on GPUs for "thinking" (Gen AI). The next phase, "Agentic AI" for "doing," will rely heavily on CPUs for task orchestration and memory for context, creating new investment opportunities in this previously overshadowed hardware.

The focus on GPUs for AI overlooks a critical bottleneck: a growing CPU shortage. AI agents rely heavily on CPUs for orchestration tasks like tool calls, database queries, and web searches. This hidden demand is causing hyperscalers to lock in multi-year CPU supply contracts.

The AI compute narrative is shifting from GPUs for training to CPUs for agentic workflows. This creates a massive new demand for processors to orchestrate tasks, manage inference, and coordinate data centers, directly fueling Intel's comeback and flipping the expected CPU-to-GPU ratio.

Mark, CTO of AMD, states that the explosion of agentic AI workflows has created an unforeseen demand for a balanced compute architecture. These complex, multi-step processes require a CPU to GPU ratio approaching 1:1, a significant shift from traditional GPU-heavy AI training and inference models.

The AI narrative has focused on GPUs for training, but the proliferation of AI agents for task execution is creating a massive, overlooked demand for CPUs. This shift to inference and orchestration is reversing Intel's recent decline.
