is the device for executing commands. Each processor is characterized by:
– a set of executable commands;
– speed of command execution in millions of operations per second (mips);
– the amount of addressable memory;
– the size of the words being processed;
– the width of the used bus.
Depending on the set and the order of the commands, the processors are divided:
– into the classical CISC processors;
– on RISC processors with a reduced set of commands;
– for MISC processors with a minimum set of long commands;
– for VLIW processors with a set of very long commands.

The central processor is the main working component of the computer, which:
– performs arithmetic and logical operations specified by the program;
– controls the computing process; and
– coordinates the operation of all devices on the computer.
In general, the CPU contains:
– arithmetic logic unit;
– data bus and address bus;
– registers;
– command counters;
– very fast cache memory of small volume;
is a mathematical coprocessor of floating-point numbers.

The speed of DDR2 is greater than that of DDR1.

This is not quite true. Of course, if we proceed from the principle of obtaining a useful frequency, then DDR2 memory looks promising. But, due to increased delays, the memory bandwidth has decreased, along with the latency of the memory subsystem has increased, as a result of which we have an approximate equality of the above-mentioned indicators.

The fastest processor – with the most gigahertz.

No, a processor with a lower core frequency may well exceed (in almost all applications) a processor with a large amount of GHz.

Intel processors are warming less than AMD processors.

This is a controversial statement. After all, different models of both companies consuming from 35W to 135W differ in the level of typical heat release (TDP), which, incidentally, is measured in different ways (the memory controller for AMD products is built-in, Intel places the memory controller outside the processor). But even with such significant differences in the method of taking readings, the difference between the heat dissipation of processors is not so significant.

Hyper-Threading makes it possible to increase the performance almost twice.

Not always, sometimes the use of Hyper-Threading (a technology that allows two virtual ones to be seen instead of one physical processor core) can lead to performance degradation. After all, the task manager is trying to evenly load two virtual cores, but in fact there is one kernel that processes requests in turn. The result of this state of things is a general decline in productivity.

Fast processors and legs have more.

This is not true. Sometimes processors with fewer contacts are much faster.

Intel processors work smoother, which can not be said about dual-core AMD processors.

This statement is completely groundless, no studies of the level of “smoothness” of the processors have been carried out.

The operating speed of a dual-core processor is twice that of a single-core processor.

This is not true, the performance gain of the processor is not directly proportional to the number of cores.

Overclocking the CPU may cause it to burn.

The processor (video card and other accessories) can burn out due to the failure of the cooling system. The overclocking process itself can not cause the above effect, if the voltage does not exceed the norm.

Overclocking the processor does not improve the performance.

No, the results of computer tests in nominal mode and after overclocking indicate that performance is still increasing.

Operating the computer with a 100% CPU load can cause it to burn.

Indeed, a 100% load of the processor and other components provokes more energy dissipated in the form of heat. But with a good cooling system, your PC does not threaten anything (in any case, for a long time, measured in months, and sometimes even for years).

Processors manufactured by AMD can not be overclocked.

It is possible, as well as processors of other companies. There is a comparative statistics of the performance of AMD processors in the nominal and overclocked state, which can serve as a proof that this process is possible.

The processor and the system unit are the same.

In fact, the processor is only a small (though very important) part, one of the components of the system unit.
