Power consumption is the most deciding factor to consider whenever you buy a graphics card. Some modern-day GPUs require an additional 6-pin, 8-pin, or both (6+8-pin) power connectors to run properly. One of the best alternatives to this is to go with low TDP graphics cards. And when it comes to low power consumption, 75W TDP GPUs are considered an ideal choice.
With an energy-efficient GPU, you don’t need a high-end power supply or 6/8-pin power connector. A 300W or 350W power supply would be enough to fuel these chips. But keep in mind one thing, low power consumption means less performance. You cannot expect a 75W TDP graphics card to perform like a 270W TDP chip. Yes, you can game on a low TDP GPU at 1080p resolution, but with few game titles.
Quick Shopping Tips
Make sure you keep in mind these things before buying a low TDP graphics card:
This is the most deciding factor to look for when choosing a low power consumption GPU. TDP stands for thermal design power and represents the maximum amount of heat that a GPU can use in Watts. This is a basic indicator that shows how much power a GPU might consume under full load. Make sure you opt for graphics cards that use less power and do not need an external power plug.
The core clock frequency plays a great role in improving the performance of your graphics card. Some GPUs can be overclocked as well to hit higher frame rates in gaming. Make sure the base clock speed of your GPU is more than 1000 MHz.
More memory size means you can easily hit higher resolutions in games. Even graphics cards that use less power come up with higher VRAM for smooth performance in gaming. Also, higher VRAM gives you more edge in open-world games.
