What is CPU?
A central processing unit (CPU) is a central unit or main processor, an electronic circuit that executes information from a computer program.
It performs basic arithmetic, controlling, logic, and input/output (I/O) operations specified by program instructions. It contrasts with the main memory, input, or output circuit, external components, and specialized processors such as graphic processing units (GPUs).
However, fundamental operations of the CPU remain the same, but the form of the CPU, design, and implementation change over time.
Moreover, the primary function of the CPU is to perform arithmetic and logic operations, but the processor register provides operands to the arithmetic logic unit, which stores the results of ALU operations.
It also helps to control, arrange, and organize in collecting, decoding, and executing information by directing coordinated operations of ALU, register, and other components.
What is RAM?
RAM is a short memory of a computer. It is abbreviated as (random access memory) where data that a processor uses is stored.
RAM enables a computer to access data faster than on a hard disk or long-term storage devices.
So, RAM capacity is critical for computer performance as it can increase your computer speed and faster data accessibility.
However, RAM allows computers to quickly access, read, and modify data. Ram is helpful for computers performing everyday tasks, such as browsing the internet, editing a spreadsheet, loading many applications, and playing and experiencing the latest heavy games.
Ram is designed to hold memory for the short term and allow computers to work efficiently and faster. A computer with more RAM can process and fetch data more efficiently.
Just consider ramming as a workspace—the larger or giant the workspace, the easier and more efficient to perform tasks.
What is GPU?
GPU is the graphic processing unit. GPU is helpful in device graphics processing and handling graphic-related work like effects, graphics, video, high-resolution games, etc. different kinds of GPU are available according to the computer system’s needs.
GPUs are integrated into your PC’s motherboard, which is thin, smart, lightweight, and power efficient in laptops. GPUs are used in both personal and professional or business computers.
However, GPUs are best known for their capabilities in gaming for extensive graphics creation, creative production, and artificial intelligence, making GPUs more popular and demanding.
Therefore, GPUs are designed to improve PC speed and accelerate and supply 3D graphics. With time GPUs are becoming more efficient, flexible, and programmable with enhancing capabilities.
GPU helps graphic programmers to create more interesting visual effects and realistic images with shadowing techniques.
Difference Between CPU, RAM and GPU
It performs basic arithmetic, controlling, logic, and input/output (I/O) operations specified by program instructions.
In contrast, RAM enables a computer to access data faster than on a hard disk or long-term storage devices.
At the same time, GPU is helpful in device graphics processing and handling graphic-related work like effects, graphics, video, high-resolution games, etc.
Comparison Between CPU, RAM and GPU
| Parameter of Comparison | CPU | RAM | GPU |
| Definition | A central processing unit (CPU) is the main processor or an electronic circuit that executes information from a computer program. | It enables a computer to data faster than from main storage like HDD. | It is helpful in graphics processing and handling graphics effects, and playing high-resolution games. |
| Usage | It performs basic arithmetic, inputs/output, logical operations, etc. | It is used for immediate data storage and retrieval. | It is used for graphical application and video rendering. |
| Location | It is also located on the top of a motherboard in the PC. | It is outside the CPU and is in the form of separate chips. | It is present in a video card, fixed in a motherboard, or in some CPU die. |
| Working | It processes input or output data and stores it. | It helps in storing and recovering data. It also enhances system speed. | GPU helps display 3D graphics efficiently by reducing the load on the CPU. |
| Cost | CPU is also expensive. | Its cost depends on its speed and efficiency, and storage. | It is also costly, depending on its efficiency. |
