What specifications to look for when choosing a graphics card?

If you enjoy gaming, you would require the latest GPUs. The faster processing of GPUs can allow you to extract maximum performance from your system. The same amount of capability is not possible with a CPU. Hence GPUs are in great demand for gaming. As newer GPUs enter into the market, the old ones are often sold on a regular basis. Gaming is one of the reasons for buying a GPU. Besides, many commercial facilities require GPUs for intensive activities. For example, workstations that process videos require the capability of GPUs. It is also useful for streaming videos and editing them. Activities like content creation can also demand faster processing as good as GPUs. Several computer aided design/manufacturing and 3D rendering may also require GPUs.

It is necessary to consider few primary specifications and features before choosing a graphics card. It is important to remember that not all features have the same weightage. Some features are more important over the others. Hence, if you have a clear idea of the essential features, you can target the right combination. 

1. Memory

Memory is one of the primary features that can affects the type of graphics card. You should get a minimum 6GB for gaming. If you will use it for games at 1080p, you can opt for something as good as 8GB or 16GB. Most of the high-resolution gaming requires a higher memory. It can help with a clear picture and faster processing.

2. Form

Form includes the length, width, and height of the graphics card. You must make sure that the card can fit into the slot. It can either be full length or half-length. It may be thick and require more slots than the usual. Most of the new generation cards may occupy two or more expansion slots. It is important to check the thickness and length in order to fit it correctly within the processor.

3. Thermal Design Power or TDP

This is another important factor that must be considered. TDP measures the amount of heat that is dissipated from the graphics card during processing. This value can also determine the right kind of PSU or power supply unit necessary for your system. A 600W PSU is sufficient for most of the previous generation graphics card. But the newer versions may require more power capacity. You must consider upgrading your PSU to higher one in order to ensure sufficient power and capability. Secondly, if you are going to overclock your system to boost speed, you must check the TDP and PSU beforehand.

4. Power connectors

The graphics card draw power through the power connectors. The standard PCIe slot act as connectors for a maximum of 75W. But the new graphics cards may require more additional slots for power supply. The additional PCIe slots come in 6-pin or 8-pin variety. The number of connectors vary in different type of cards. You can check the additional connectors provided in the card.

5. Ports

This includes the different kind of ports like HDMI and DisplayPort. In order to connect your graphics card to the monitor, you must make sure that the card has the necessary ports for the monitor. If it does not contain the ports, you may have to purchase additional adaptors.

6. Clock Speed

It is an important feature that determines the productivity, capability, and processing speed of the system. The base clock speed acts as the default speed as provided by the manufacturer. If you are looking for a particular intensive game, you can check the minimum requirements in order to ensure the right clock speed. If the system has an overclocking feature, you can increase the clock speed to boost speed. It is important to know the overclocking potential to know the maximum possible limit especially for intensive games.

7. CUDA cores or stream processors

Cores form the integral part of the GPU. It translates to the productivity and processing of the graphics card. But in order to understand the performance based on the number of cores, you must compare it within the same architecture. For example, you cannot compare different architectures like Navi and Vega within the AMD. At the same time, you cannot compare graphics card from Nvidia and AMD based on number of cores alone. It can help you to understand the processing capability when you know the minimum recommendations.


You can get an idea about the maximum performance of a graphics card based on the value of TFLOPS. It refers to the trillions of floating-point operations per second. When the core count is multiplied by the clock speed, multiplied by two, you would get the value of TFLOPS. It can help you to determine how fast a graphics card is when compared against the others from the same architecture. 

9. Memory speed/bandwidth

A higher memory bandwidth can lead to more productivity and capability as compared to a lower bandwidth. Just like clock speed, memory, and CUDA cores, the memory bandwidth is also important before choosing the right type of graphics cards.

Understanding the types of GPU for choosing a graphics card

There are two types of GPUs- integrated and discrete. The two types differ in their placement style. An integrated GPU is built into the CPU itself. It may have slower processing power as it is integrated with the CPU of the system. Their performance is often restricted, making it ideal for only slow-processing tasks. On the other hand, a discrete GPU has its own circuit board and separate processing setup. This leads to faster processing in activities that demand it. For example, if you are looking for a GPU specially for gaming, you can opt for a discrete type. Once you decide the type of GPU, you can look at different price ranges. You may find low-level, mid-range, and high-end offering a wide range of features and processing capacity. 

You can choose a laptop GPU if you prefer to enjoy gaming on the move. Laptop GPUs may not offer the same level of processing power as you can expect in a computer GPU. It may also lead to overheating if there are no cooling elements. Due to the limitation in the space of a laptop, you cannot expect a high level of performance capability in a laptop. You may experience restrictions for activities like video streaming, 3D rendering, and content creation. For these activities, it is best to explore GPUs on computers. 

GPUs are upgraded on a continuous basis. One of the recent features includes ray tracing. It is an upgraded feature in new AMD and Nvidia GPUs. They offer exceptional processing capacity that can stream data in a faster way. It involves realistic lighting effects in gaming that recreate the real world in a flawless manner. Such upgrades have increased the demand for GPUs. As newer versions are created regularly, you can expect them to enter into the market at reasonable cost. These GPUs expand the portfolio of activities and allow you to enjoy gaming and video-related activities.
