Understanding Central Processing Units (CPUs): Key Concepts and Manufacturers
This module covers essential hardware concepts focusing on Central Processing Units (CPUs). The CPU is known as the brain of the computer, with major manufacturers being Intel and AMD. Intel produces faster, often more expensive CPUs with names like Core i3, i5, and i7, while AMD offers cost-effective alternatives such as Athlon and Phenom series. Understanding the differences, pricing factors—like processor speed, cores, and interface—is crucial for making informed purchasing decisions for computer systems.

Central Processing Units • The CPU functions as the brain of the computer.
Manufacturers • Intel and Advanced Micro Devices (AMD) are the two largest manufacturers of CPU’s. • Both make CPU’s found in common computer systems.
Intel • Intel currently manufactures the fastest CPU’s on the market, and their CPU’s are often more expensive than those made by AMD. • Intel’s CPU’s use names such as Pentium, Celeron, Core2 Duo, Core 2 Quad, Core i3, Core i5, and Core i7.
AMD • AMD’s CPU’s are often less expensive. • AMD CPU’s have names such as Sempron, Athlon 64 X2, Athlon II, Phenom X2, Phenom X4, and Phenom II.
PGA Pin Grid Array CPU’s have pins on the CPU that plug into a motherboard socket.
LGA Land Grid Array CPU’s have Pins on the motherboard and contact points on the CPU.
Factors that affect CPU price: • Processor Speed • CPU Interface (Motherboard Dependent) • Number of Cores • Cache • Bus Speed • Manufacturer
Which to Purchase? • Both AMD and Intel make excellent CPU’s. Always perform research, read reviews, and make your decision based on the intended use of the computer and the allotted budget.
