CPU techonologies Flashcards
CPU Clock speed
A constant speed that is a multiplier of the crystal osciallator.
Maintains a steady rate for tasks to be completed.
A good CPU clock speed is 3.5 GHz to 4 GHz.
bits to bytes
8 bits to 1 byte
Machine Language
code that allows communication with CPU through binary
CPU manufacturers
- Intel
- AMD
- ryzen
speed a CPU works at depends on
- cores
- threads
- hyperthreading?
- overclocking?
- pipelining?
CPU cores
CPUs now have multiple so multiple tasks can be manipulated at the same time
pipelining
having the next task being processed before the one being processed is finished. If the first process takes longer to process or is lost, data in the pipeline can be lost
overclocking
depending on the core, you can increase the clock speed multiplier in the BIOS.
CPU cache
data and instruction can be stored in the CPU cache rather than sending and reading from the RAM
CPU register
holds onto a certain piece of information for further manipulation or execution
hyperthreading
Allows you to use more than one task/thread on one core at a time
CPU cache lvl.1
- 64K of RAM (fastest cache memory)
- runs at the speed of CPU
CPU cache lvl. 2
- 128/256K of RAM (mediocre cache memory)
- runs at half the speed of CPU
CPU cache lvl. 3
- Megabytes of RAM (slowest cache memory)
- runs at the speed of CPU
address bus
wires from CPU to RAM sending what address to get information for
