MLPerf Client is a newly developed benchmark created in collaboration with MLCommons, aimed at evaluating the performance of large language models (LLMs) and other AI workloads on personal computers (from laptops to desktops to workstations). This benchmark simulates real-world AI tasks to provide clear metrics on how systems handle generative AI workloads. The MLPerf Client working group hopes this benchmark will drive innovation and competition, ensuring that personal computers can meet the challenges of an AI-driven future.
