1️.What is a GPU?

A GPU (Graphics Processing Unit) is a processor designed for rendering graphics, video processing, and parallel computations. It is widely used in gaming, video editing, and AI acceleration.

🔹 Strengths:
✔️ Excellent for general-purpose parallel processing
✔️ Used for gaming, video editing, and AI model training
✔️ Versatile and widely available

🔹 Limitations:
❌ Consumes more power than NPUs
❌ Not optimized specifically for AI inference

2️.What is an NPU?

A NPU (Neural Processing Unit) is a dedicated AI processor designed to accelerate neural network computations. It is optimized for deep learning, AI inference, and machine learning tasks.

🔹 Strengths:
✔️ Optimized for AI tasks (e.g., deep learning, speech recognition)
✔️ Faster and more efficient than GPUs for AI inference
✔️ Consumes less power

🔹 Limitations:
❌ Not as versatile as GPUs (mainly used for AI-specific tasks)
❌ Still developing compared to established GPU technologies
