Company responsible for manufacturing Phenom, Athlon, Duron, Sempron, and Opteron processors.
Refers to the number of internal pathways of a CPU, 32-bit or 64-bit
Specialized memory residing on-board the processor or processor packaging that stores the information just used by the CPU in an effort to predict what the processor will need next
Central Processing Unit
The brains of the computer
Clock Speed
The maximum rate a CPU can process data per second, referred to in Megahertz or Gigahertz
CPU speed rating measuring billions of cycles per second
Heat Sink
Metal clip-on device, generally made of aluminum, which sits on top of a CPU and other chips and used in conjunction with a fan to dissipate heat from the CPU
Intel technology that combines two processing threads together allowing a single processing core to process two threads at one time making it seem like two processors
Integrated Graphics Processing Unit
Feature built into the processor die on a CPU to assist with graphics functions
Land Grid Array
Chip interface standard that has pins on the circuit board instead of on the chip packaging; the chip has flat pads that interface with the pins by surface contact only
