Difference between RAM and Processor

Introduction to RAM and Processors (CPU)

People are still perplexed by what a processor and ram accomplish for their CPUs, despite the fact that they have been there for many years. The truth is, both are required in the construction of any computer. They work in various ways, but they must be in sync to do so. While understanding the distinctions will not make you a computer expert, it will assist you in understanding your computer components, budgeting sensibly, and purchasing what you actually require for your computer.

What is RAM (Random Access Memory)?

A RAM is a type of computer data storage where information is kept and is abbreviated from the terms “random-access memory.” This data may come from your operating system, games, media, and other sources, and will most likely be accessed by your processor. It’s similar to your hard drive, but it’s more faster to read and write because it’s connected directly to your CPU. The significant difference is that RAM can only store data while your computer is running, whereas data on hard drives will remain accessible even if your computer is turned off.

Consider RAM to be a person’s short-term memory, and your hard drive to be their long-term memory. While it is continually storing information, it also forgets about other facts. This has to do with how your computer operates. If your RAM is full, it will overwrite existing data with fresh data that is currently being accessed. Your computer’s speed will be affected as a result of this.

Have you ever noticed how everything goes nicely when you first turn on your computer? This is because your memory is still fresh and you haven’t stored too much knowledge. Furthermore, the technical limits (access time and architecture design) of a RAM play a role in the speed and performance of the device.

Note that the speed of RAM is determined by the amount of data it can hold, its type, and how quickly data can be accessed. DDR 3 @ 1866 MHz (16 GB)

What is a processor ?

The processor, often known as the central processing unit or CPU, is an electronic circuitry that executes program instructions by performing fundamental arithmetic, logical, control, and I/O (input/output) activities. It is even referred to as the computer’s “brain” by some.

Modern CPUs are microprocessors that are housed on a single integrated circuit (IC) chip. These are the kind of files that are stored on our computers, laptops, cellphones, tablets, and other electronic devices. Multi-core processors, which are nominally single processors but have the power of two or more CPUs, are now available. This only goes to show that manufacturers, engineers, and developers are always looking for new ways to make our CPUs quicker so that users can have speedier computers.

A Processor’s Three Major Operations

Fetch — Retrieves a program memory instruction (usually from hard drives)
Decode — This function translates the instruction into signals that control other components of the CPU.
Execute – To carry out activities that have been encoded. It might be made up of a single action or a series of acts.
The speed of a CPU is determined by its clock speed, cache, and cores. (Quad-core processor with 8M cache, 4.0 GHz)

Processor vs. RAM

What is the difference between a processor and a RAM?

While they both have the same goal of speeding up computers, their differences are so substantial that putting one together or merely upgrading one takes a thorough understanding of both.

Which of the two, RAM or processor, do you believe has the greater impact on your computer’s speed? You are accurate if you replied RAM, but you are also correct if you answered the latter. So, how does this happen?

Information that must be calculated and processed is stored in RAM. Your computer will get data from your hard drive, which contains the necessary files for your operating system, when it starts up. Your processor will now read the information and translate it into action. You might wonder, “Why not just get it from the hard drive?” Simply put, the RAM and processor have a unique relationship that allows them to operate and cooperate far more quickly than the processor and hard disk. This is due to the fact that they are connected by a direct line, which makes their connection more reliable than the hard drive’s.

In terms of speed, a RAM is measured by the amount of storage it has, but a processor is measured by the number of cycles per second it can complete. When it comes to setting up your system, here is when it becomes complicated. Because the speed of a processor is proportional to its RAM, if you have a 2.0 GHz processor and 4 GB of RAM, increasing your CPU is the better option. What is the reason for this? Simply put, at a processor speed of only 2.0 GHz, the RAM is not completely utilized. Your processor can only perform so many calculations before running out of memory. Due to the speed of your processor, even if you have 16 GB of RAM, the space in that memory will not be filled with information. This is referred to as a bottleneck. RAM and processors are inextricably linked and must be well-balanced.

RAM is substantially less expensive than a processor in terms of cost. A low-end RAM with 2 GB of memory will set you back around $12.00, while a low-end processor with a 3.4 dual core processor would set you back around $24.00. A high-end RAM with 16 GB of memory will set you back roughly $60.00, and a high-end processor with a 4.00 GHz quad-core would set you back approximately $350.

Note that the speed of a CPU is determined not only by its clock speed, but also by its cache and number of cores. RAM is evaluated not only in terms of its capacity, but also in terms of its type and access time.
