- Optimized for Deep Learning: Designed to handle complex neural network operations and deep learning tasks with enhanced speed and efficiency.
- Cloud-Accessible: Once exclusive to internal Google operations, Ironwood is now available through Google Cloud Platform, eliminating the need for dedicated hardware.
- Enhanced Performance: Builds on previous TPU generations to deliver faster computation and greater energy efficiency for large-scale AI workloads.
key differences between TPU, GPU, and CPU
| Aspect | CPU (Central Processing Unit) | GPU (Graphics Processing Unit) | TPU (Tensor Processing Unit) |
| Purpose | General-purpose processor for everyday computing tasks | Designed for parallel processing, especially graphics & ML | Specialized for AI and deep learning, especially tensor operations |
| Architecture | Few powerful cores (2–16), optimized for sequential tasks | Thousands of smaller cores for parallel processing | Fewer, highly specialized cores optimized for matrix operations |
| Performance | Slower in AI workloads due to sequential nature | Faster than CPUs for ML and parallel tasks | Fastest for training and inference of deep learning models |
| Flexibility | Highly versatile across a wide range of tasks | Moderately flexible, good for ML and graphics | Narrowly focused on specific AI operations |
| Efficiency | Less energy-efficient for AI tasks | More efficient for parallel computations | Highly energy-efficient for machine learning workloads |
| Best Use Case | Running operating systems, software, everyday applications | Graphics rendering, video editing, and ML model training | AI-specific tasks like neural network training and inference |
| Example Usage | Browsing, spreadsheets, OS management | Gaming, deep learning training | Powering AI in Google Search, YouTube, and DeepMind models |
