Choosing the right GPU

Purchasing a graphics card does not need to be puzzling we’ll clarify the whole thing you need to know about GPUs The graphics card (also known as the GPU) in your PC or laptop is one of the most vital components, and while GPUs are mainly used by gamers to push cutting edge visuals at ultra-high resolutions, they can also play a very vital role for artistic specialists.

Two main kinds of GPU: integrated and dedicated. An integrated graphics card is when the graphics processing unit is fundamentally built into the same chip as the processor (CPU). Pretty much every up-to-date CPU comes with integrated graphics, and these have plentifully of assistances. For a start, it means you don’t have to worry about getting a GPU, as there will already be one with the CPU. However, while integrated graphics are fine for day-to-day use, they are not powerful enough to handle modern games and advanced 3D applications. They can also struggle with rendering high resolution videos. So, if you’re after more power, you’ll want dedicated graphics (also known as discrete graphics). These graphics cards slot into your PC’s motherboard and can give it a huge upgrade in graphical performance and they are made by  Nvidia and AMD, the two biggest names in discrete graphics. Not only are dedicated graphics more powerful, but they can be bought separately, which means you can upgrade your PC with them in the forthcoming. Certain laptops also come with discrete graphics cards, giving them the kind of performance you’d usually expect from a desktop PC. Obtaining a dedicated graphics card can have a huge effect in your creative work, with 3D rendering, video editing, game design and animation all advancing from the extra power. But what would you look for?

Outputs of a graphics card are also important as it determines what (and how many) displays you can attach – and what resolutions they support. All modern graphics cards should at least have a HDMI port. This is a universally accepted port that makes it easy to hook up any modern monitor or projector. Most HDMI ports support up to 4K resolution at up to 60Hz. There’s also DisplayPort, another popular video out port, which supports 4K up to 120Hz and 8K at 30Hz. By looking at each of these provisions, you’ll be able to get a decent knowledge of the kind of performance to assume from a graphics card, and select one that best suits your wants.

Clock speed another important spec you’ll see thrown around when talking about graphics cards are their clock speeds. This speed, measured in megahertz (MHz), fundamentally tells you how fast the graphics processing unit can render graphics – therefore, the higher the MHz, the faster the graphics card – and the better it will be for gaming and rendering.

Video Memory one of the most vital specs for a graphics card is the amount of video memory (also known as VRAM) it has. The memory on a video card is dedicated to graphics tasks, and stores image data for quick access. Part of this contains the Z-buffer, which includes information regarding the depth of objects in a 3D space from certain perceptions, and is used in computer games and for creating CGI effects for pictures.
