Study Notes
Motherboard Compatibility
When considering a processor upgrade or replacement, motherboard compatibility is a crucial factor to ensure the new processor works seamlessly with the existing system.
Key Factors to Consider:
- Socket Type: The processor socket on the motherboard must match the new processor's socket type. Common socket types include LGA, PGA, and ZIF.
- Chipset Compatibility: The motherboard's chipset must be compatible with the new processor. Check the motherboard manual or manufacturer's website for supported processors and chipsets.
- Voltage and Power Requirements: The motherboard must be able to provide the required voltage and power to the new processor. Ensure the motherboard's power delivery system can handle the new processor's power requirements.
Checking Motherboard Compatibility:
- Check the Motherboard Manual: Consult the motherboard manual or documentation to find compatible processor lists and specifications.
- Manufacturer's Website: Visit the motherboard manufacturer's website to check for compatible processor lists, BIOS updates, and documentation.
- Online Resources: Utilize online resources such as CPU-Upgrade.com or CPU-World.com to check compatibility and find compatible processors.
Upgrading vs. Replacing:
- Upgrading: If the motherboard is compatible, upgrading the processor may be a viable option. However, this may require a BIOS update to support the new processor.
- Replacing: If the motherboard is not compatible, replacing the motherboard may be necessary to ensure compatibility with the new processor.
Important Considerations:
- ** BIOS Updates**: Ensure the motherboard's BIOS is updatable to support the new processor.
- Hardware Compatibility: Verify that other hardware components, such as RAM and peripherals, are compatible with the new processor and motherboard.
- Warranty and Support: Check the motherboard's warranty and support status before upgrading or replacing the processor.

- Warranty and Support: Check the motherboard's warranty and support status before upgrading or replacing the processor.
CPU Architecture
Components
- Control Unit (CU) retrieves and decodes instructions, generating control signals to execute instructions
- Arithmetic Logic Unit (ALU) performs arithmetic and logical operations
- Registers provide small, on-chip memory for temporary data storage during processing
- Cache Memory serves as small, fast memory for frequently accessed data
Instruction Cycle
- The fetch stage retrieves an instruction from memory
- The decode stage decodes the instruction into a format the CPU can understand
- The execute stage carries out the instruction
- The store stage stores the results of the instruction
Instruction Set Architecture (ISA)
- CISC (Complex Instruction Set Computing) uses more complex instructions to perform multiple tasks
- RISC (Reduced Instruction Set Computing) employs simpler instructions that can be combined to perform tasks
Pipelining
- Pipeline stages consist of a series of stages that an instruction goes through to be executed
- Pipeline depth refers to the number of stages in the pipeline
- Pipeline latency is the time it takes for an instruction to go through the pipeline
Execution
- In-Order Execution involves executing instructions in the order they are received
- Out-of-Order Execution executes instructions out of order to improve performance
Branch Prediction
- A branch is an instruction that changes the flow of execution
- Branch prediction refers to the CPU's prediction of whether a branch will be taken or not
- The Branch Prediction Unit (BPU) makes the branch prediction
Multithreading
- A thread is a sequence of instructions that can be executed independently
- Multithreading allows a CPU to execute multiple threads concurrently
- Simultaneous Multithreading (SMT) enables a CPU to execute multiple threads simultaneously
