How to Choose a Microprocessor

The microprocessor or central processing unit (CPU) is the most important part of your computer. If you are building or upgrading your personal computer (PC), then follow these steps to help you choose the best microprocessor for your needs.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Microprocessor specifications
• Motherboard specifications

1. Evaluate how you plan to use your computer. A computer used primarily for surfing the Internet and homework does not need the processing speed or power that a gaming or multimedia computer does.

2. Consult your budget. Intel-brand microprocessors are more expensive than AMD microprocessors.

3. Compare microprocessor clock speeds. The clock speed determines how fast your computer will run. The Intel Pentium 4 and AMD Athlon microprocessors have speeds averaging 2.0 gigahertz. The Intel Celeron and AMD Duron operate at lower speeds.

4. Compare microprocessor cache memory. Cache memory keeps data readily available for when the CPU needs it. A larger cache size stores more data.

5. Pay attention to the bus speeds. A higher bus speed allows your microprocessor to communicate with the rest of your computer faster.

6. Make sure the microprocessor's slot or socket size matches that of your computer's motherboard. You can't use a microprocessor that does not fit in your computer.

Tips & Warnings

• To avoid the need to upgrade too soon, get the fastest microprocessor your budget allows.
• Make sure that your power supply can handle the microprocessor.
• Add a heat sink or more efficient fan to keep the microprocessor from overheating.
