AI Focused Semiconductors
Semiconductors created for Artificial Intelligence

AI-focused semiconductors are specialized chips designed to accelerate artificial intelligence (AI) and machine learning (ML) computations. Unlike general-purpose CPUs (central processing units), AI-focused chips are optimized for the parallel processing demands and heavy mathematical workloads required by AI models, particularly neural networks. These chips play a crucial role in both training and inference stages of AI, making them integral to various industries, from data centers to autonomous vehicles and robotics.

Types of AI-focused Semiconductors Include:

There are several types of AI-focused semiconductors, each optimized for different types of AI workloads:
