quad=4
dual=2
core=teras
maksud multi core.. tp ni maybe istilah ntuk computer... maybe sama je kot ngan instilah ntuk hp
A multi-core processor is an integrated circuit (IC) to which two or more processors have been attached for enhanced performance, reduced power consumption, and more efficient simultaneous processing of multiple tasks (see parallel processing). A dual core set-up is somewhat comparable to having multiple, separate processors installed in the same computer, but because the two processors are actually plugged into the same socket, the connection between them is faster. Ideally, a dual core processor is nearly twice as powerful as a single core processor. In practice, performance gains are said to be about fifty percent: a dual core processor is likely to be about one-and-a-half times as powerful as a single core processor.
Multi-core processing is a growing industry trend as single core processors rapidly reach the physical limits of possible complexity and speed. Companies that have produced or are working on multi-core products include AMD, ARM, Broadcom, Intel, and VIA. Both AMD and Intel have announced that they will market dual core processors by 2005. At their 2004 Fall Developer Forum Intel predicted that, excepting their Celeron line, 40% of all processors the company ships will be multi-core by the end of 2006.
A quad-core processor is a chip with four independent units called cores that read and execute central processing unit (CPU) instructions such as add, move data, and branch.
Within the chip, each core operates in conjunction with other circuits such as cache, memory management, and input/output (I/O) ports. The individual cores in a quad-core processor can run multiple instructions at the same time, increasing the overall speed for programs compatible with parallel processing. Manufacturers typically integrate the cores onto a single semiconductor wafer, or onto multiple semiconductor wafers within a single IC (integrated circuit) package.
Although it's tempting to suppose that a quad-core processor would operate twice as fast as a dual-core processor and four times as fast as a single-core processor, things don't work out that simply. Results vary depending on the habits of the computer user, the nature of the programs being run, and the compatibility of the processor with other hardware in the system as a whole. The best results are usually seen when running many programs simultaneously, or in situations that require massive, brute-force arithmetic calculations
kalo pc.. bleh je upgrade... tukar processor...
kalo hp xleh.. yg bleh hanya o.c a.k.a overclock
