Term | Definition |
---|---|
Level 3 (L3) cache | Cache memory further from the processor core than Level 2 cache, but still in the processor package. |
liquid cooling system | A method to cool overclocked processors that uses a small pump inside the computer case and tubes that move water or other liquid around components and then away from them to a place where fans can cool the liquid. |
memory cache | A small amount of faster RAM that stores recently retrieved data, in anticipation of what the CPU will request next, thus speeding up acess |
MMX (Multimedia Extensions) | Multimedia instructions built into Intel processors to add functionality such as better processing of multimedia, SIMD support, and increased cache. |
multi-core processing | A processor technology whereby the processor housing contains 2 or more processor cores that operate at the same frequency, but independently of each other |
multiplier | The factor by which the bus speed or frequency is multiplied to get the CPU clock speed. |
multiprocessor | A system that contains 1 or more processors. |
octo | A processor package that contains 8 cores and supports 16 instructions at once. |
overclocking | Running a processor at a higher frequency than is recommended by the manufacturer, which can result in an unstable system, but is a popular thing to do when a computer is used for gaming. |
PowerNow! | An AMD technology that increases performance and lowers power requirements for processors. |
processor frequency | The frequency at which the CPU operates. Usually expressed in GHz |
quad core | A processor package that contains 4 cores and supports 8 instructions at once. |
S1 state | The ACPI power saving mode where the hard drive and the monitor are turned off and everything else runs normally. |
S2 state | The ACPI power saving mode where the hard drive, monitor, and the processor are turned off. |
S3 state | The ACPI power saving mode where everything is shut down except RAM and enough of the system to respond to a wake-up call such as pressing the keyboard.(Sleep Mode) |
static RAM (SRAM) | RAM chips that retain information without the need for refreshing, as long as the computer 's power is on. They are more expensive than traditional DRAM. |
stop errors | An error at the kernel level that is severe enough to cause the operating system to stop all processes. |
thermal compound | A cream like substance that is placed between the bottom of the cooler heat-sink and the top of the processor to eliminate air pockets and to help to draw heat off the processor. |
triple core | A processor package that contains 3 core processors, thus supporting 6 instructions at once. |
