Features & Performance

The Nvidia GeForce RTX runs the top PC games at higher resolution and faster refresh rates. It makes high-end gaming more affordable for every average gamer. 

Nvidia paired RTX 3080 with a 10GB GDDR6X memory using a 320-bit interface. This graphics card operates at a 1440 MHz frequency that can be overclocked to 1710 MHz, and the memory runs at 1188 MHz. 

GeForce RTX 3080 is built on Ampere graphics architecture. It is the latest graphics architecture by Nvidia. RTX 3080 has around 46% more SMs than RTX 2080. It has second-generation RT cores, which function like the first-generation RT cores but provide more efficiency. 

Moreover, it is a dual-slot card with a dual-slot cooling solution. It has 68 raytracing acceleration cores. This graphics card is connected to the system through PCI-Express 4.0x16 interface.

Its display outputs include a 3x DisplayPort 1.4a and 1x HDMI 2.1 When it comes to standard designs, Nvidia has never gone with a better design that is more functional than this new one. 

The manufacturer designed a short, multi-layered PCB to make the entire back-end of the card a heatsink. Nvidia placed a fan at the back of the graphics card. 

It allows sucking cold air through the heatsink and expelling it upwards and out. The black and silver design of the RTX 3080 looks professional. The only visible thing is the ‘GeForce RTX’ logo in white on the side. 

The Nvidia GeForce RTX 3080 is not just about gaming. Nvidia has developed some new features for RTX 3080. You can use it for almost everything, but it is still one of the best choices for PC gaming. 

Choosing a Power Supply for the RTX 3080 GPU

NVIDIA RTX 3080 is a powerful and capable graphics card for your PC. You will need a high power supply to make the RTX 3080 perform effectively. A power supply converts alternating current (AC) from a power outlet into the computer’s direct current (DC). 

Choosing a Power Supply for the RTX 3080 GPU

Every graphics card has average and maximum power usage. The RTX 3080, at its highest, uses nearly 340 Watts. It needs a power supply with at least 700 Watts, more than twice the maximum usage.

Your power supply must be capable of powering your entire computer even when your GPU reaches its peak power consumption when playing heavy and high-graphics games. That is why the manufacturers recommend using at least 750W PSU for the RTX 3080. 

However, you can also use 650W PSU if you do not afford a 750W PSU. It is important to purchase a suitable PSU from reliable brands and trusted platforms to avoid any threats like instability issues or system crashes.
