Chapter 1: Understanding Intel Core Processors
What is a Processor (CPU)?
The Central Processing Unit (CPU), often called the "brain" of the computer, handles all instructions from hardware and software. Intel's Core processors are designed for different levels of performance, from basic computing to high-end gaming and professional workloads.
Intel Core Branding Explained
Intel categorizes its processors into four main families:
- Intel Core i3 – Entry-level, budget-friendly
- Intel Core i5 – Mid-range, balanced performance
- Intel Core i7 – High-performance for gaming & productivity
- Intel Core i9 – Extreme performance for professionals
Each family has multiple generations (e.g., 10th Gen, 11th Gen, 12th Gen Alder Lake, 13th Gen Raptor Lake, 14th Gen Meteor Lake).
