So, you’re probably wondering, “What’s the difference between a GPU and a graphics card?”Well, let’s dive in and clear up any confusion!

A GPU, or Graphics Processing Unit, is a chip that’s responsible for rendering images and videos on your computer screen. It’s the brain behind the graphics, and it works by taking data from the CPU (Central Processing Unit) and turning it into images that you can see.

On the other hand, a graphics card is essentially a separate piece of hardware that houses the GPU and its memory. It’s responsible for generating the signals that are sent to your monitor, and it’s what allows you to experience high-quality graphics and smooth gameplay.

While some computers have integrated graphics (meaning the GPU is built into the CPU), dedicated graphics cards are typically more powerful and offer better performance for demanding tasks like gaming, video editing, and 3D rendering.

So, in short, the GPU is the processing power, and the graphics card is the hardware that allows you to see the results of that processing power.

You might be wondering how fast your graphics card can actually run, and the answer lies in its clock speeds and boost clocks.

The clock speed of a graphics card is the speed at which the GPU runs. It’s measured in MHz or GHz, and the higher the clock speed, the faster the GPU can process data. For example, a graphics card with a clock speed of 1.5 GHz can process data faster than a graphics card with a clock speed of 1.2 GHz.

Boost clocks, on the other hand, are a newer feature that many modern graphics cards have. These clocks allow the GPU to run at a higher speed than its base clock speed when it is under heavy load. This means that you can get better performance out of your graphics card when you need it most, such as when playing a demanding game or rendering a complex video.

Boost clocks are usually listed as a range, such as 1500-1800 MHz, indicating the minimum and maximum speeds the GPU can run at.
