CPU has various types, architecture 32bit and 64bit , speed and capabilities. While the long drawn debate for replacing RAM or CPU would enhance a computers performance settles at both being equally important, it is worth noting the differences between the two. Another important difference between the two is that the CPU also known as the processor performs the task of processing an instruction while the RAM is the unit that provides the information needed to carry out the function.
The performance capacity of a RAM is measured by the number of programs a computer can run at a time while the performance of a CPU is measured by the speed by which a program is launched. This is because the better the processor the faster it can retrieve information from the RAM.
However the performance of RAM is limited by the speed of the processor and bus speed of the motherboard whereas the speed of the CPU is limited by the number of cores installed in the processor. Although this result may vary checking the Task Manager would give an accurate result of their performances.
What is RAM? What is CPU? A CPU has multiple components which perform different work. It has an arithmetic logic unit which has a responsibility to perform simple arithmetic and logical tasks. It also contains a control unit that handles the various parts of the computer. It has the responsibility to read and interprets instructions from memory and convert them into a series of signals to start operations of the other computer parts.
The control unit also calls the arithmetic logic unit to perform the necessary calculations from time to time. In the CPU operations, cache memory is used which is high-speed memory where instructions can be copied and retrieved quickly. High-end CPUs may have six hexa-core or even eight octo-core processors. A computer may also have more than one CPU, which each have multiple cores. A CPU executes an instruction by fetching it from memory, using its ALU to perform an operation, and then storing the result to memory.
RAM also know as computer memory unit is that part of the computer hardware which handles all the memory and caching related operations of the processor. The address translation is also known as address binding and it uses a memory map which is programmed by the operating system. The difference between the two are in how they refresh, or speed. In terms of seconds, DRAM gives access times of about 60 nanoseconds. SRAM does the same in 10 nanoseconds. When a computer system performs certain task like rendering the video for a game or calculating numbers to add in the spreadsheet, then the certain series of instructions are needed to be processed by the central control unit.
The number of instructions run by the processor can be measured in the megahertz which means millions or billions of instructions can be processed per second. Numerous modern processors have multiple cores nowadays, that means sub parts which are capable of running different programs and components of the programs in the parallel line. On the other hand, to smoothly run operations, most of the programs required a certain amount of memory to store the working data.
In contrast, there are two or more slots for RAM in a motherboard. Because of this, it is common practice for people who are tight on budget to splurge on the processor then just get a single RAM module. They can later add more RAM modules when they have the budget. It is also worth noting the processors and the motherboard they use are specific to a certain manufacturer.
A motherboard that takes Intel processors cannot take an AMD processor and vice versa. You should take that into consideration in building your system as you cannot switch brands without replacing your board and CPU. On the other hand, RAM can be used with either brand. Cite APA 7 , l.
