How do multiple core processors work and what process does the manufacturer use to clock the hertz?
AndrewSavagefb5608
A "core" is all the circuitry needed for one CPU. Early processors like 8080A, Z80, 6502, 8088, 68000 and so on contained one core per package. If you wanted to build a multiprocessor computer with single-core chips, you had to put multiple chips in the machine. Apple made a few of them, but not very many people bought them because only a few programs could use multiprocessing. Photoshop has supported multiprocessing for a long time, so most of the people who bought those machines were serious Photoshop pros.
The "multiple core" processors they sell today are made with multiple CPUs in the same package. To get the multicore feature to work, they wrote support for it into the operating system, and now all programs can use it.
A CPU's hertz is clocked by multiplying a reference frequency from a crystal oscillator. You might have a 3GHz chip, say, but there's no way in the world you'd want 3GHz radio frequency running around inside your computer - microwave and near-microwave frequencies are REAL picky about the circuits they're in. If you didn't have an expansion board shoved all the way in, you could wind up jamming all the satellite dishes in your neighborhood. But in the CPU, which can be properly shielded, they're fine.

Why does Intel and AMD processors benchmark at comparable levels when the processor speed is different?
Clock speed is only a useful comparison of speed when two processors share the same architecture. AMD and Intel processors have different internal architectures. At various points in time, one manufacturer had a more efficient architecture than the other, thus providing better performance at a lower clock speed. As of Q2 of 2009, Intel currently offers more efficient processors.
What type of computer applications would be enhanced by a dual-core processor?
Not many. Without being specifically written to take advantage of multiple processors or else recompiled with altered settings, to do so, software gains no advantage from multiple processors (or 'cores'). However, you still have the advantage of 'extra processor power' in general (e.g. two processors of the same type is still twice the processing power of a single processor of that type). The move to multiple cores and multiple processors has more to do with physical limitations which prevent manufacturers from simply increasing the 'clock' as had been the case for about a decade previously.
What is a single core ghz?
"Single core" refers to the computer's main chip having a single processor. Newer models, such as Intel's i3, i5 and i7, have multiple processors (2, 4, or 6 processors), usually called multiple "cores", on a single chip. GHz refers to the clock speed of each individual processor. It gives you a rough idea of how fast it can process data. However, the processing speed will also depend on other factors.
What is clock speed of i7 processors?
The clock speed of an i7 processor can range anywhere from 1.70 GHz to 2.90 GHz depending on the quality and brand. Some processors are built better than others resulting in better clock speeds.
What is pipelining in computers?
Pipelining is based if clock cycles to process a command, in every clock cycle , three or four circuits sat idle, Today these circuts are orginized in a conveyer belt fashoin called pipelining.With pipelining each stage does ots own job with each clock cycle pulse, creating a much more efficient process. The CPU has multiple circuts doing multiple jobs.
What advantage do dual-core and quad-core processors have over single core processors?
The most gaping advantage can be very easilly explained through example: Single core processors have a single thread, and can process a single set of instructions per clock cycle. This looks like this (Saying this processor can process 2 instructions a clock): (Note this is in an optimal setting where data is perfectly threaded) Clock 1: Instruction 1; Instruction 2; Clock 2: Instruction 3; Instruction 4; Clock 3: Instruction 5; Instruction 6; Clock 4: Instruction 7; Instruction 8; Dual-Core processing would do this same instruction set much quicker: Clock 1: Instruction 1; Instruction 2; Instruction 3; Instruction 4 Clock 2: Instruction 5; Instruction 6; Instruction 7; Instruction 8 In a perfectly threaded application, two equivilent-performance cores on a dual core processor would power through the work twice as quickly as a single-core model. A quad-core with these specs would do the entire instruction set in a single clock. Even if it isn't always a 2x increase, multiple-core procesors have a distinct advantage in a very large range of applications.

Is system clock the heart of computer?
No, the system clock is not the heart of the computer but the micro-processor. The basic characteristics that differentiate the micro-processors includes the instruction set, bandwidth, and the clock speed.
Processors that can execute more than one instruction per clock cycle?
super scalar
How do you know if your grandfather clock is a Simon Willard?
There are several ways to find out if your grandfather clock is a Simon Willard. A person can take the clock to a dealer or there may be markings on the clock, which will tell the manufacturer.
Does GHz represent processor?
No. It represents the clock speed of the processor. The clock speed is usually misinterpreted by many as the power of the processor, but the physical design of the processor has far more to do with the processors throughput than the clock speed itself.
What advantage do dual-core and quad - core processors have over single core?
The most gaping advantage can be very easilly explained through example: Single core processors have a single thread, and can process a single set of instructions per clock cycle. This looks like this (Saying this processor can process 2 instructions a clock): (Note this is in an optimal setting where data is perfectly threaded) Clock 1: Instruction 1; Instruction 2; Clock 2: Instruction 3; Instruction 4; Clock 3: Instruction 5; Instruction 6; Clock 4: Instruction 7; Instruction 8; Dual-Core processing would do this same instruction set much quicker: Clock 1: Instruction 1; Instruction 2; Instruction 3; Instruction 4 Clock 2: Instruction 5; Instruction 6; Instruction 7; Instruction 8 In a perfectly threaded application, two equivilent-performance cores on a dual core processor would power through the work twice as quickly as a single-core model.
