Things You'll Need:
- Microprocessor specifications
- Motherboard specifications
-
Step 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.
-
Step 2
Consult your budget. Intel-brand microprocessors are more expensive than AMD microprocessors.
-
Step 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.
-
Step 4
Compare microprocessor cache memory. Cache memory keeps data readily available for when the CPU needs it. A larger cache size stores more data.
-
Step 5
Pay attention to the bus speeds. A higher bus speed allows your microprocessor to communicate with the rest of your computer faster.
-
Step 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.
