CPU and System Performance
Karten in diesem Stapel (15)
- 1What does CPU performance depend on?clock speed, number of cores and cache size.
- 2what is clock speed?the number of instructions a single processor core can carry out per second (Hz).
- 3What is the average clock speed for computers?3.5GHz
- 4What is over-clocking?Setting the clock speed higher than the factory-set rate.
- 5What can over-clocking lead to?overheating, crashing or permanent damage to the system. Water cooling is usually needed.
- 6What does each core do?independently process data
- 7How many cores do PCs and smartphones have nowadays?4 or more cores
- 8What is a cache?data storage inside the CPU, much faster than RAM.
- 9What benefits do a large cache bring?faster access to more data it needs to process.
- 10What does too little RAM do?makes the computer run slower due to the use of virtual memory
- 11How do you upgrade RAM?replace the RAM sticks with higher capacity ones.
- 12What benefits do more RAM bring?more applications / more memory-intensive applications it can smoothly run
- 13What is a GPU?graphical processing units
- 14what do GPU's do?handle graphics and image processing, relieving the processing load on the CPU.
- 15If i was unhappy with my graphics, what would I do?installing a dedicated GPU (graphics card)
