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.
