The CPU is best for executing a wide variety of tasks quickly & provides the best performance per-core. These are some of the differences between the CPU & GPU.

The GPU only Interacts with the memory & the display unit to decide how to display the pixel on the screen. It Interacts with multiple computer components such as RAM, ROM, I/O ports to perform instructions. While the GPU receives the data from CPU & generates the visual images accordingly. The GPU is optimized for Parallel instruction operation.ĬPU concentrates on the computation of any data received. The CPU is optimized for sequential instruction operation. The GPU focuses on maximum throughput (parallelism, number of instruction execution in a time interval). The CPU mainly focuses on the low latency (the time delay between instructions & data transfer). It required less RAM as compared to CPU that is why integrated GPU shared the RAM with CPU. It requires a more memory RAM as compared to GPU. Its runs at a lower clock speed of around 800 MHz but it has hundreds to thousands of processing cores. Its processing speed is very high & runs at a very high clock speed of about 3 to 5 GHz but fewer processing cores. The GPU is made of multiple weaker cores to perform a simple repeated operation. The CPU may have a few powerful cores to distribute the workload. While GPU’s sole purpose is to process images & 3d graphics much faster than CPU. It can generally execute any kind of task including graphics but not in a very optimal way. The GPU has limited instruction & capable of only graphics-related tasks. Here are some of the differences between CPU & GPU provided in the form of a table ĬPU is more flexible with a larger instruction set & can perform a wide range of tasks.

The GPU is best at performing a simple repetitive task intensively, therefore they can be used for simple non-graphical tasks as well such as bitcoin mining & password decoding that relies on huge data that can be processed in parallel. This is what makes the GPU faster & better than CPU at rendering visual data. The benefit of using a large number of cores is to provide high-throughput, execution of multiples instructions at the same time. So it does not need a processor with wide range capabilities but rather a processor with multiple parallel cores with a limited number of instructions.
Rendering is a simple arithmetic operation that is done over & over again. The cores are a bunch of ALUs designed to execute simple instructions in repetition. The GPU is made of relatively more processing core but they are weaker than the CPU.
It converts the data from one graphic format to another or creates 2D or 3D images called rendering.
The G PU or Graphic Processing Unit or normally called Graphic or video card is a special purpose microprocessor specifically designed & optimized to process graphical data. What is a GPU (Graphics Processing Unit)? Related Post: Difference Between RAM and ROM – Comparison.The ALU job is to perform any arithmetic or logical operation on the data provided by the memory, and the control unit controls the flow of data. The CPU consists of ALU (arithmetic logical unit), CU (Control Unit) & Memory. The CPU or the Central Processing Unit is made up of millions of transistors & is commonly referred to as the brain of any computer that is responsible for processing any data. What is a CPU (Central Processing Unit) ? Related Post: Difference Between Microprocessor and Microcontroller.But before going into that, let’s discuss what CPU & GPU really is. In this article, we are going to discuss the differences between CPU & GPU. The CPU (Central Processing Unit) & GPU (Graphics Processing Unit) have multiple common features such as they are both processors made from millions of semiconductor transistors & they are capable of processing digital using some algorithms.
