1. AI Training: A GPU – heavy configuration (60 – 70% GPU, 20 – 30% CPU, 5 – 10% FPGA) dominates, as training demands massive parallelism. CPUs handle data preprocessing and model coordination, while FPGAs assist in specialized tensor operations.
2. AI Inference: FPGAs gain prominence (30 – 40% FPGA, 30 – 40% CPU, 20 – 30% GPU) for low – latency responses. Their reconfigurability adapts to trained models, with CPUs managing workflow and GPUs handling residual parallel tasks.
3. Big Data Processing: A balanced mix (40 – 50% CPU, 30 – 40% GPU, 10 – 20% FPGA) works best. CPUs manage data indexing and query execution, GPUs accelerate parallel data transformations, and FPGAs optimize I/O operations.

Technical Considerations Shaping the Ratio

• Performance Requirements: Latency – sensitive applications prioritize FPGAs, while throughput – focused tasks lean toward GPUs.
• Power Constraints: FPGAs shine in low – power environments, while GPU – intensive setups demand robust cooling solutions.
• Cost Efficiency: CPUs offer a cost – effective base, with GPUs and FPGAs adding incremental value based on task criticality.
