CPUs Flashcards
Overclocking
Changing the base speed of your motherboard or increasing the CPU’s metronome multiplier
Intel and AMD
The two primary CPU manufacturers
System Crystal (Quartz Oscillator)
Acts as a metronome for a fixed clock rate on the motherboard (Usually a few hundred MHz)
Clock Multiplying
CPUs take the System Crystal clock speed and multiply it (2x, 10x, 30x etc..) for its own clock speed
Multiple Cores
Multiple Pipelines that can process code being sent to the CPU
Hyper-threading
A singular pipeline (core) being able to process multiple pieces of code at the same time
Gigahertz
1 Billion times per second
L1 Cache (Level 1)
64k of RAM (Runs at the same speed as CPU)
L2 cache
A lot bigger than L1 in terms of size and it feeds into the L1 Cache
L3 Cache
Megabyte size and runs about the same speed as the Motherboard
CPU Socket
Physical package of the CPU. Includes Shape, the Pins, form of the CPU and the actual socket that the CPU goes in
Caching
Works between the RAM and the CPU. The CPU runs much faster than the RAM. So the CPU stores lines of code in the cache that aren’t needed right away
SRAM
The RAM inside the CPU used for Caching
External Data Bus
RAM feeds code into the CPU through the External Data Bus
Micro-architecture
The circuit diagram on the inside of the CPU.
Family Names - assigned to different new Micro-architecture. (Ex. Coffee Lake, i3)
