2.9 Understanding CPU Architecture and Performance Saved Flashcards
What does each core in a CPU do?
Each core acts as an individual processor, capable of executing tasks independently.
What is a dual-core CPU?
A CPU configuration with two cores.
What is a quad-core CPU?
A CPU configuration with four cores.
What is an octa-core CPU?
A CPU configuration with eight cores.
What is multithreading?
Enables a CPU to run multiple threads (instruction sets) on a single core.
What is Intel’s Hyper-Threading Technology (HTT)?
Simulates two virtual cores for every physical core, improving efficiency by allowing the CPU to execute tasks during idle cycles.
Can boost performance by 15-30%, depending on the workload.
What is cache in a CPU?
A small, high-speed memory integrated into the CPU, storing frequently used data to reduce access times.
What is L1 Cache?
Closest to the core, offering the fastest access.
What is L2 Cache?
A bit larger but slower, sometimes shared across cores.
What is L3 Cache?
Larger and shared among all cores to improve overall performance.
What does clock speed measure?
Measured in GHz, it determines how fast a CPU can execute instructions.
What is overclocking?
Pushing the CPU beyond its rated speed to improve performance, which increases heat and power consumption.
What is essential for heat management in overclocking?
Proper cooling, such as fans or liquid cooling, is essential to prevent instability or hardware damage.
What are socket types?
CPUs fit into specific motherboard sockets, such as LGA for Intel or AM4 for AMD.
What is virtualization support in CPUs?
CPUs today support hardware-based virtualization, allowing multiple operating systems to run on a single machine.
