What is CPU?
The CPU, or Central Processing Unit, is a crucial hardware component of a computer. It consists of several microprocessors that contain tiny switches to control the flow of electricity through various circuits. The central hub of the CPU is the motherboard, the main circuit board that connects all the computer's hardware components.
CPU is mostly founded with personal desktops and laptops. In laptops, it is integrated within the device, while personal desktops demand an external CPU.
CPU Features?
Let’s decode the prime CPU features that are useful for computational tasks.
Functions
There are several aspects of the operating system, but the CPU’s primary purpose is to perform instructions given by a software program, such as arithmetic, logic, and I/O controls. It also controls the flow of data within the computer in various ways.
Components
The CPU encompasses an MMU, which is the shorthand for the memory management unit, a CU, which stands for the control unit, and a cache. The MMU controls access to data between the CPU and the main memory, or RAM, abbreviated by the acronym RAM. It also ensures that all parts of the CPU are in phase or in step with the other to prevent inequality of beats. Cache memory is faster than RAM and is placed on the processor’s chip, causing it to be closer to the CPU.
Performance
CPU performance can be measured by several characteristics, including CPU performance can be measured by several characteristics, including:
About GPU
A GPU (Graphics Processing Unit), is an electronic microprocessor used for rendering and computing responsibilities that are graphic-related. Picture it as a junior partner with the main CPU, offloading the graphics processing unit which means you’ll get a better and smoother gaming experience, video editing, or 3D animations among others.
GPU Features and it's Special
The following are some of the features associated with GPUs.
Cores
It will always be the case that GPUs are designed with hundreds of individual cores, the ability of which to support thousands of threads at one time and thus optimize the product.
Video Memory
Video memory is, however, not a part of the traditional memory in a computer more than the random access memory or RAM but rather a feature of the GPU. Hence, as aimed at controlling big bandwidth size from graphical-use applications, it has been specially planned for this purpose.
Cooling Systems
Some models of GPU are equipped with fans or exhaust systems to avoid heating and speed up the process to the level of efficient cooling.
Low Latency
Some specific GPUs available today are configured to improve and measure system latency to realize focused performance enhancement and improved target-acquisition and reaction times.
Game Ready Drivers
Game-ready drivers in GPU give consumers the choice to set graphics preferences ‘on the fly’ with a button click and additionally incorporate the best of NVIDIA technologies.
Now that you have read about the GPU and CPU features, let’s move on to the main part of this blog: GPU and CPU comparison.
CPU vs GPU Difference: A Comparison Table
GPU vs CPU: In a Details
1. Core Count
CPUs have fewer cores (Generally 4-16 but less), but all these cores are more potent and have a better operational capability. This makes them ideal for single-threaded operations, such as simple web browsing or for running selected software. On the other hand, GPUs have a significantly higher number of cores, orders of magnitude higher than CPUs, with core numbers in the hundreds or even thousands. However, the computational power of each of these individual cores is significantly less than that of a core in the CPU. This design enables them to perform well in parallel computation, which is a process of splitting complex calculations into sections that can be solved at the same time.

2. Processing Style
CPUs are asynchronous in nature as they are aimed at serial processing, that is, step-by-step execution of instructions. This is best for generic operations but can be problematic when conducting complicated tasks that require a large number of calculations. On the other hand, GPUs are excellent examples of parallel computers. They can handle numerous chores simultaneously, which is something that makes them best suited for use in applications like video editing and expansive simulation tasks.
3. Memory Access
This is usually larger and directly accesses the main system memory (RAM) for data, known as the CPU cache. This is used for fast data access and fast data transformations for utilitarian and generic computing applications. Specifically, while CPUs have larger caches and RAM but are not specially designed for high data throughout, GPUs have smaller caches and GDDR designed for high bandwidth, but the data must be transferred from the CPU, which can be a bottleneck on some occasions.
4. Functions
The CPU functions as the brain behind the computer, which in turn directs all key operations. It is in charge of executing programs, controlling data movement, and translating orders into something tangible. On the other hand, GPUs use different processors to manage a number of tasks at the same time and deliver outputs that are later combined to achieve something more advanced than the composing parts. Its design facilitates fast performance on a wide range of repetitive computations. This makes it suitable for generating complex images and enhances high-speed computation.
How Does CPU Working?
A CPU can do many things fast but is limited in how many things it can do at once. It interprets most of a computer’s commands, like basic instructions that drive the computer. The CPU fetches program instructions over its instruction side (IS) bus, reads data over its data side (DS) bus, executes the instructions and writes the results over the DS bus.
How Does GPU Working?
A GPU is designed to render high-resolution images and video fast. It’s made up of many smaller, more specialized cores that work together to deliver huge performance when a processing task can be split across many cores at the same time. GPUs can do simple and repetitive tasks much faster because they can break the task down into smaller pieces and do them in parallel. GPUs are also used for non-graphical functions like machine learning and scientific computation.
Commonalities between GPUs and CPUs
1. Core
GPU and CPU have cores that do all the computations and logical functions. The core pulls instructions from memory in the form of digital signals called bits. It decodes the instructions and runs them through logical gates in an instruction cycle. CPUs used to have only one core, but now we have multi-core CPUs and GPUs.
2. Memory
Both CPUs and GPUs do millions of calculations every second and use internal memory to speed up processing. The cache is the built-in memory that gives quick access to data. In CPUs, the labels L1, L2 or L3 indicate cache hierarchy. L1 is the fastest, and L3 is the slowest. A memory management unit (MMU) controls data movement between the CPU core, cache and RAM in every instruction cycle.
3. Control Unit
The control unit coordinates the tasks and decides the frequency of the electric pulses the processing unit generates. Higher-frequency CPUs and GPUs are better. However, the design and configuration of these components are different for CPUs and GPUs, so they are useful in various scenarios.
