Things to Look for in the Best External Graphics Cards for Laptop

Graphics cards are expensive equipment, and you are purchasing a new one. Certain factors must be considered:


The first factor to consider is the cost. You must understand what you can afford and expect in this price range. Another important consideration is whether your Laptop has the processing power to support a powerful graphics card. If you’re stuck with a low-cost processor, there’s no point in investing in an expensive graphics card.


Graphic cards are a heat-generating powerhouse. They usually generate a lot of heat. TDP is the unit of measurement for heat output. If a graphics card’s TDP is high, it will require more fans and coolant to distribute it, and more fans mean more power consumption. A good GPU must be capable of dissipating heat and should not overheat easily.


Another factor to consider when purchasing a GPU is its power. It’s a good idea to double-check that the power supply has enough 8-pin or 6-pin connections for your graphics card. Choose a power supply rated at least 80 Plus Bronze to ensure this.


The GPU memory can range from 2 GB to 12 GB. Many people debate whether the memory of graphic cards matters or not. We considered video card memory essential because it supports anti-aliasing operations, eliminating rough edges on graphics, textures, and other features required to bring your graphics to life. Video memory is crucial in image quality because it lets you play games at higher resolutions.

The optimum memory of a graphics card should be at least half of laptop RAM; if the RAM of a laptop is 16GB, the memory of 8GB would be a decent choice.


The amount of memory that the GPU can access at any given time is bandwidth. When a GPU has a higher bandwidth, data is delivered to the shader cores more quickly. As a result, games and video visuals run smoothly and clearly. To grasp bandwidth, you must first understand how it works. Bandwidth is calculated by combining memory speed and bus width.

Shader Cores

Shader cores breathe life into images by adding light and dark variations to 3D objects. When a graphics card has more shader cores, it can quickly and accurately render images. However, GPUs with fewer shader cores in some video games outperform GPUs with more shader cores.

Shader cores, bandwidth, memory, power, pricing, space, and cooling should all be considered before purchasing a graphics card. Similarly, it is always good to check online reviews and forms.
