What's the difference between a cpu and a gpu?

[om2580]

CPU and GPU are different because they are tasked and built to handle different tasks and do things in a different way.

A CPU is composed of a small number of cores and has high caches designed to handle much more complex tasks.

A GPU is composed of as much as 1000's of cores that are much simpler but run things in parallel to give you a high speed computational power.

A CPU is the central processing unit of the computer, whereas a GPU is the graphical processing unit of the computer.

CPU stands for central processing unit.program instructions are executed in order to derive the necessary data.
GPU stands for Graphical processing units. GPUs, are what give you the video and graphics that appear on your screen.

Hardware wise, GPUs and CPUs are similar but not identical. The specialized nature of GPUs means that it can do its task much faster than a CPU ever can, but it is not able to cover all of the capabilities of the CPU.

GPU architectures are becoming increasingly programmable, offering the potential for dramatic speedups for a variety of general purpose applications compared to contemporary general-purpose processors (CPUs).

CPU is Central processing unit and GPU is graphical processing unit

The CPU (central processing unit) has often been called the brains of the PC. But increasingly, that brain is being enhanced by another part of the PC – the GPU (graphics processing unit), which is its soul. All PCs have chips that render the display images to monitors. But not all these chips are created equal

The main difference between CPU and GPU architecture is that a CPU is designed to handle a wide-range of tasks quickly (as measured by CPU clock speed), but are limited in the concurrency of tasks that can be running. A GPU is designed to quickly render high-resolution images and video concurrently.

Because GPUs can perform parallel operations on multiple sets of data, they are also commonly used for non-graphical tasks such as machine learning and scientific computation. Designed with thousands of processor cores running simultaneously, GPUs enable massive parallelism where each core is focused on making efficient calculations.

Hey there!
As measured by CPU clock speeds, CPUs are designed to handle a wide-range of tasks quickly, but their concurrency is governed by the number of tasks that can run at one time. Graphics processing units (GPUs) render high-resolution images and videos simultaneously.
Since GPUs can perform parallel operations on multiple sets of data, they are also used for non-graphic tasks such as machine learning and scientific computation. GPUs can run thousands of cores simultaneously, which enables massive parallelism, which allows each core to focus on completing calculations efficiently.

GPU stands for Graphic Processing Unit
CPU stands for Central Processing Unit
GPUs are generally targeted to process lots of vector-type data for graphics. It’s fairly targeted.
CPU is more of a generic processor that is more targeted for doing various operations, especially control code, and not necessarily at high-performance processing. However, it can be tasked to do so.
You didn’t mention DSP - but this is a Digital Signal Processor. Its processor is optimized for high-speed processing of numeric data representing analog signals in real time. It tends to be much more power efficient than a general CPU for such an operation.
These were reasonably short descriptions but should give you the gist of their differences.

[Danielsmithh]

The basic difference is that a CPU has a small no. of cores which are very complex and a GPU has about 1000 cores which are simple. A CPU is used for processing and caching data whereas a GPU is used for rendering and making graphics.

[SamHobbs]

Another important difference I have found is that whereas the machine language of CPUs are documented the machine languages are seldom documented. The reason is that the machine language of GPUs are usually different for each model of GPU.
