Answers: What are the differences between CPUs, GPUs, TPUs, and DPUs?

• Computer architecture
• Central Processing Units
• Graphics Processing Units
• Tensor Processing Units
• Data Processing Units
• Quantum Processing Units

What it concludes

• CPUs are optimized for sequential computations and complex branching logic.
• GPUs are optimized for parallel computing and matrix multiplication.
• Increasing CPU core count eventually hits diminishing returns due to power consumption and heat dissipation.
• TPUs are designed specifically for tensor operations and deep learning workloads.
• DPUs offload networking, routing, security, and data storage tasks from the CPU.
• Quantum computers threaten modern RSA encryption through Shor's algorithm.
