Central Processing Units(CPU’s) Written by Tim Keyser Georgia CTAE Resource Network 2010
Central Processing Units • The CPU essentially functions as the brain of the computer.
Manufacturers • Intel and Advanced Micro Devices (AMD) are the two largest manufacturers of CPU’s. • Intel is substantially larger than AMD but they 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 found in the same spectrum of computers which use Intel CPU’s, but they are often less expensive. • AMD CPU’s use names such as Sempron, Athlon 64 X2, Athlon II, Phenom X2, Phenom X4, and Phenom II. • Both manufacturers develop innovative technologies that lead to advancements in the field.
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.
