5.  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.

6. Pin Grid Array CPU’s have pins on the CPU that plug into a motherboard socket.

7. Land Grid Array CPU’s have Pins on the motherboard and contact points on the CPU.

8.  Processor Speed  CPU Interface (Motherboard Dependent)  Number of Cores  Cache  Bus Speed  Manufacturer

9.  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.
