Thermal Design Power (TDP): The GPU that is discrete is usually the most power-hungry part of the modern PC. If you’re planning to build or upgrade your computer, then you’ll need to make sure that the power supply is adequate to power the GPU that you plan to install.

Like all equipment that requires electricity GPUs produce a significant amount of heat, and need sufficient cooling to operate efficiently and with maximum performance. Many graphics cards include the power supply recommendations that usually include suggested Watts (such as 775 Watts.

 You’ll have to take into consideration the amount of power drawn by other components on your computer and make sure that your power source can support all components within your system.

The total amount of power the GPU draws and the amount of heat it produces is referred to in the industry as “thermal design power, also known as TDP. The measurement is expressed in watts and is the amount you’ll find in the graphic card’s specifications.

The greater the TDP is, the higher the power required to operate the GPU and the greater heat the GPU generates. This can be crucial on laptops as well as desktops in which thermals are the top priority due to the limited space.

Take note that while making your PC design or selecting for a GPU upgrade, you’ll be looking to determine how hot a specific graphics card can run at its maximum power. This will allow you to choose the most appropriate cooling system for your GPU and for the computer itself.

It’s also essential to know what type of power connectors that a graphics card requires. It is usually a mix of connectors with eight pins and six-pins but it can differ. Modern GPUs may have different power configurations, therefore when you are upgrading or adding an GPU it is important to make sure that your power supply has enough power, but that it is equipped with the correct connections that can meet the power requirements of your GPU.



Discrete GPUs make use of a particular kind of memory to store the necessary data to eventually display information on a display. If you are considering discrete GPUs you should consider the amount of memory a graphics card can hold, and also the bandwidth it can provide.

Video random access memory (VRAM) within your GPU is crucial for games with high-performance that require huge amounts of data in order to create the intricate images that appear on screen. It is also an issue when using multiple screens particularly if they are more detailed or have a higher refresh rate.

Generally speaking, you’ll gain more RAM for graphics when you purchase more powerful graphics cards. And, when you purchase an GPU that is fast enough to play your preferred games, you’ll have enough VRAM. Check out cr50ing price online in India.

The higher the speed of RAM has; the more quickly the GPU can access data in order to show it onto the screen. The GPU model typically determines the type of RAM in a graphics card therefore; if you pick the appropriate GPU to meet your requirements it’s likely that you’ll find the appropriate RAM for it.


Today, most discrete GPUs connect to PCIe slots. The majority make usage of the 16x version of PCIe. GPUs varying terms of how many slots they can fill and are available in single; double as well as triple-slot configurations.

 It is essential to ensure that your motherboard on your PC is large enough to accommodate the GPU you’ve chosen. Also, you need to take into consideration the other components you’d like to connect to the GPU in conjunction with it; especially when they will make use of PCIe slots.

It is also important to make sure that your case is big enough to accommodate the components you’re installing. Although most contemporary PC cases can support regular Gaming GPUs; in case you are considering the small Form Factor PC, or an extremely big GPU; you should research the compatibility between your motherboard case along with your graphic card. A lack of space could lead to inadequate cooling, which could cause a reduction in performance.

If space limitations are an issue There are GPUs that were designed specifically for a slimmer footprint.


Of course the fact is that the GPU alone isn’t efficient. It requires connectivity to a motherboard, as well as an LCD, or several displays, to be able to function. There are various connections that modern displays use which include DVI, HDMI, and DisplayPort.

VGA is an older connection that may be used on certain display models; but it is rapidly disappearing into the background.

The most common configuration of the latest gaming hardware is 3 DisplayPort outputs and one HDMI.

The difference between various display connections is a subject that merits an entire article. It is enough to say that you should make sure that your graphics card has enough connections for the various displays you plan to connect to your computer; and that you have the correct connections. 

In many instances, you can purchase adapters to change a connection from the graphics card into one that the display will accept; however this may hinder access to features such as larger resolutions and higher refresh rates.

It is important to check for specifications and make sure that the graphics card is able to support any number of monitors that you wish to connect; and also that you can connect to your graphics card and the monitors.

Multiple GPUs

Certain graphics cards can be connected to work in parallel with other cards; which could provide significant performance boosts when playing games with high demands. This is known as Scalable Link Interface (SLI) for Nvidia as well as Crossfire in the case of AMD. If you wish to run several graphics cards on your computer it is necessary to select the correct cards; and the motherboard that is compatible with this technology.

This configuration isn’t as widespread as it was. The popular 3070 and 3080 series of Nvidia cards don’t provide the option of SLI in any way; since few games can support more than two GPUs. If you’re looking to have broad coverage for SLI or Crossfire then you should choose older GPUs. If you choose to do this you’ll lose the latest technologies, such as Ray Tracing. So, think the options carefully.

I hope you’ve got an understanding of what you want to see in the GPU. Once you’ve mastered the basics, it’s a great option to go to Newegg’s GPU section for more details. Use the comparator tool to get a side-by side listing of how various graphics cards stack up; and assist you in choosing the most suitable device for your system.

Another source that can aid you in selecting the right GPU as well as a graphics card is the games and programs that you’re planning to run. They will typically list the necessary or recommended specifications. These will typically include the recommended CPU, RAM, GPU, as well as storage.
