What is a benefit of Google's purpose-built servers compared to standard servers?

Google designs custom hardware - such as Tensor Processing Units (TPUs) for ML inference and training, and custom network interface cards for its Jupiter network fabric - specifically to maximize performance per watt for targeted workloads. This task-specific optimization allows Google's infrastructure to outperform commodity servers on those tasks in terms of throughput, latency, and energy efficiency. The specialization is the core benefit over standard, general-purpose server designs.

Purpose-built servers are designed for forward-looking performance optimization, not for backward compatibility with legacy storage hardware.

Custom silicon and purpose-built hardware typically require significant R&D investment and are more expensive to design and manufacture than commodity servers.

The software running on Google's infrastructure is not inherently incompatible with standard servers; the advantage is performance efficiency, not software exclusivity.
