GPU vs TPU for AI Quiz

Answers and explanations appear as you take the quiz.

1. Which frameworks does the guide list as supported for Cloud TPU workloads?
   • JAX, TensorFlow, and PyTorch/XLA
   • CUDA C++ only
   • PyTorch CPU and ONNX Runtime only
   • TensorFlow Lite only
2. Who designs the TPU?
   • NVIDIA
   • Google
   • Intel
   • Apple
3. What core hardware structure makes TPUs efficient at matrix multiplication?
   • A spinning magnetic disk
   • A large mechanical relay bank
   • A systolic array of multiply-accumulate units
   • A single ultra-fast core
4. Which system factors can affect a GPU-versus-TPU performance comparison?
   • Only the accelerator’s peak operation count
   • Only the number of parameters in the model
   • Only the cloud region name
   • Model support, software, interconnects, memory, utilization, and deployment cost
5. What is a practical strength of GPUs relative to TPUs for many teams?
   • A broad ecosystem of CUDA libraries, tools, and existing GPU-supported workloads
   • A guarantee that every model is faster on a GPU
   • A requirement that all training use TensorFlow
   • A built-in advantage in every cost comparison
6. Why does the guide recommend benchmarking the intended workload on the specific platform?
   • Peak operation counts always predict end-to-end speed exactly
   • Measured results depend on workload shape, kernels, input pipeline, memory, and system scaling
   • All workloads use the same hardware path and precision
   • A benchmark removes the need to check software support
7. What should a team compare before choosing between a GPU and a TPU for training?
   • Peak FLOPS alone for an unrelated precision
   • The chip’s name and product launch date
   • End-to-end time and cost for its model, framework, input pipeline, and target scale
   • A benchmark from a different model and software stack
8. How does Google describe a TPU pod?
   • A single GPU with no network
   • A CPU-only cluster
   • A model format
   • A group of TPU chips connected through a high-speed interconnect
