What Makes a Good GPU?

Put simply, the graphics card or GPU is used to show what appears on your computer’s screen. Anything from the background or screensaver of your PC to a character moving in a game will be processed by the GPU. The graphics card can make or break your gaming experience. It is similar to a CPU in that it has multiple cores which process information. One of the main differences between the GPU and the CPU is that the GPU has thousands of cores, all of which are focused on graphical tasks. 


What Makes a Good Graphics Card?

If you are comparing this graphics card at https://www.lenovo.com/gb/en/faqs/intel/intel-graphics/ with others to find the best option for you, there are lots of things to keep in mind when choosing a decent graphics card. The clock speed, memory, memory speed, memory bandwidth and RAMDAC speed are some of the most important. The GPU clock speed and how much memory is on the GPU are the two most important things to consider when you buy a graphics card. This is because these two aspects have the most impact on the apps and games that you use, determining how smoothly your computer is going to run.


Clock Speed Explained

Your graphics card clock speed refers to the speed that your GPU renders graphics at. Because of this, having high clock speeds is important if you want to play games or render images and videos at a very high speed. Because of this, the clock speed is one of the most important things to consider before you choose the right graphics card for your needs.


GPU Memory

Similar to the RAM in your computer, the VRAM or the GPU’s memory is the temporary storage for your graphics card. It will make it easier and faster for the GPU to grab memory of its own rather than use that which is already in your system, ultimately meaning that over time, your system doesn’t need to work as hard because it is relying on the GPU’s separate memory instead. However, it’s worth bearing in mind that you won’t increase performance by choosing a GPU with a lot more memory than you actually need, so figure out where the sweet spot is.


Can You Just Use Your CPU?

Yes, you can just rely on the integrated graphics in your CPU for everyday applications and in some cases, even gaming. However, it is likely to be difficult for your computer to run many games or run the latest versions of most games unless you adjust your settings quite a lot. Even then, it’s highly unlikely that your computer will struggle to run the games as smoothly as you like, because the CPU has fewer, more complicated cores compared to the GPU, which means it’s not very efficient at rendering graphics as it will only focus on one, rather than several tasks at a time.


Whether you just want a better picture when using your computer or are looking for a better gaming experience, it’s important to know what to look out for when choosing the right GPU.
