Factors to consider when buying a GPU

Graphics cards transform numerical values into visual representations. Nowadays, most CPUs include an integrated graphics card (GPU). These GPUs are excellent for showing 2D Graphics, text, and windows, but they are not well-suited for videogames or other visually heavy tasks. If you’re a gaming enthusiast and want a quality graphics card, such as the amd rx 6700 xt, buy a dedicated GPU. Since GPUs are among the costliest parts of a computer, extra care must be taken to ensure you pick the correct one. There are eight factors to consider while selecting the appropriate graphics card.


It makes little sense to equip an inexpensive car with pricey components. Similarly, adding a costly GPU to a low-cost computer equipped with a cheap processor doesn’t make sense. Experts recommend allocating 30% of the total PC building expenditure to a GPU. With 30% of your budget set aside, you’ll be able to acquire a fantastic GPU at a reasonable price.


GPUs generate a great deal of heat. This heat production is represented by the TDP figure, which is critical when selecting a GPU. If your TDP value is high, the pc will require additional fans to dissipate heat effectively. Because fans require additional room and power, the TDP number is significant. Smaller computer towers require GPUs with low thermal design power, whereas larger computer towers offer greater flexibility.


Apart from the TDP value, you’ll need to evaluate whether your power supply has adequate 8- or 6-pin connectors for the graphics card. This is accomplished by investing in a reliable power source.


The majority of graphics cards feature between two and twelve GB of video RAM. However, there is considerable controversy over the amount required for optimal computer performance. While some forums state that memory is irrelevant, others state that it is a critical factor to consider when selecting a graphics card.

It’s critical because video card memory stores anti-aliasing operations (which smooth down hard edges on objects) and textures that help bring your visuals to life. Video memory is critical for visual quality since it enables higher-resolution gaming.

As a result, you must divide the system memory by half and use this figure to determine the amount of RAM required for the graphics card. For instance, if your system has 8GB of RAM, you’ll need a minimum of 4GB graphics card to achieve optimal performance.


While the value of GPU memory is arguable, many agree on the critical nature of bandwidth. The bandwidth of a GPU refers to the amount of memory that it can retrieve at any given moment. Data is sent to the shader cores more quickly when a GPU has increased bandwidth. As a result, video graphics and games operate smoothly and clearly. To comprehend bandwidth, one must first comprehend how it works. Bandwidth is calculated by combining bus width and memory speed.

  1. The clock speed of the graphics card: The clock speed is expressed in megahertz (Mhz) and affects frame rate, input lag, and latency. As a general rule, GPUs can read 64 bits at a time. To improve performance, however, many GPUs read many chips simultaneously.
  2. Width of the graphics card’s bus: For instance, if a GPU can access two 64-bit chips concurrently, it’s reading 128 bits rather than 64. This results in a bus width of 64 x 2.

Shader cores

Shader cores have a significant impact on bandwidth. Shader cores breathe life into graphics by giving three-dimensional objects changes in light and shadow. When graphics cards have more shader cores, they can produce images faster and more accurately. However, there are instances when GPUs with fewer shader cores outperform GPUs with more shader cores in specific video games. When selecting a graphics card, shader cores, memory, bandwidth, pricing, power consumption, cooling, and available space are all factors to consider. Similarly, it is always prudent to study internet reviews and forms.

Hopefully, this article’s given you an idea of what you want in a GPU. If you’re a gamer looking for a high-end graphics card, e.g. the amd rx 6700 xt, buy a GPU with the suggestions mentioned above. Another factor to consider when selecting a GPU is the games you intend to run. Most will give required, recommended, and ideal specifications, including the CPU, RAM, GPU, and storage recommended.
