Study Notes
CPU (Central Processing Unit)
- The CPU, or processor, acts as the computer's brain, executing instructions by using logic gates.
- It accepts programs/instructions and performs arithmetic and logical operations.
- The CPU connects to the motherboard via a socket that establishes electrical connections with the motherboard bus.
- This bus connects the CPU to other system components (RAM, storage, video, expansion cards).
Clock Speed
- Clock speed (measured in GHz) determines the rate at which the CPU executes instructions.
- A faster clock speed generally allows more instructions per second.
- CPU, motherboard, and RAM must all be synchronized to the same clock speed.
Overclocking
- Overclocking involves running the CPU beyond its designed speed for a potential performance increase.
- While potentially offering performance enhancements, overclocking leads to hotter operation and higher electricity consumption,
- This can shorten component lifespan and potentially cause system instability.
- Turbo Boost (Intel) dynamically increases speeds as needed.
CPU Cache Memory
- CPU cache is fast built-in memory for storing frequently accessed information from system RAM.
- It's made of SRAM (static RAM), much faster than DRAM (system RAM).
- This speeds up performance when data is needed repeatedly.
Multi-Core Processors
- Early CPUs had one core.
- Modern CPUs have multiple cores within a single package, enabling concurrent instruction execution.
- More cores mean greater processing potential.
Multithreading
- Allows a single core to execute two instructions concurrently.
- Enhances performance, particularly in multi-core processors.
Hyper-Threading
- Introduced by Intel, hyper-threading makes one physical core appear as two to the operating system.
- It enables simultaneous processing within a single core.
- Performance increase is approximately 20%
Integrated GPU
- GPU (Graphics Processing Unit) is a specialized processor for displaying images, animations, and video.
- An integrated GPU is built onto the CPU chip.
Virtualization
- Virtualization lets multiple operating systems run on a single physical machine.
- Virtual machines appear as separate systems on a unified platform.
- Virtualization relies on CPU support.
Cooling
- CPUs generate significant heat.
- Cooling is crucial to prevent CPU failure .
- Cooling methods include heatsinks, fans, heat pipes, and radiators, all using thermal paste to enhance heat dissipation.
CPU Selection Criteria
- Prioritize system purpose to choose a CPU suited for the task.
- Verify CPU compatibility with the motherboard socket and BIOS/UEFI firmware.
- Evaluate beyond clock speed; consider architecture, core count, multithreading, and cache for a complete picture.
- Benchmarks (like cpubenchmark.net) aid in objective comparison.
- Assess the cost-performance trade-off. Intel usually offers higher performance at a premium, while AMD generally provides lower cost options.
