How Do FPGAs And GPUs Compare In Terms Of Latency?

FPGAs have lower latency because they can be customized for specific tasks, making them ideal for real-time applications. GPUs, while excellent for parallel processing, generally have higher latency due to their general-purpose design.

Which Is More Energy-Efficient, An FPGA Or A GPU?

FPGA and GPU energy efficiency depends on the complexity of the tasks they perform:

  • For simple tasks, the GPU is more efficient, using 1.1 to 3.2 times less energy per frame than others.
  • For more complex tasks and complete vision pipelines, the FPGA is more efficient, using 1.2 to 22.3 times less energy per frame than others.

FPGAs are generally more energy-efficient than GPUs because they can be tailored to perform specific tasks without unnecessary components, reducing power consumption. GPUs, designed for high versatility and parallel processing, typically consume more power.
