Dual GeForce RTX 2080 8GB — what it is

The ASUS Dual GeForce RTX 2080 8GB is a PCI Express 3.0 graphics card built on the NVIDIA Turing architecture. It delivers 2944 CUDA cores with a 1515 MHz base clock and 1830 MHz boost clock in OC mode. The 8GB GDDR6 frame buffer runs at 14000 MHz across a 256-bit bus for high-resolution gaming and content creation.

Dual GeForce RTX 2080 8GB — who it suits

This card fits builders who need a 2.7-slot design with 10.53-inch length for standard ATX cases. It drives up to four displays via three DisplayPort 1.4 outputs, one HDMI 2.0b port and a USB Type-C connector. Users requiring PCI Express 4.0 bandwidth or a smaller two-slot form factor should consider other models.

Dual GeForce RTX 2080 8GB — deciding specification

The 256-bit memory interface paired with 8GB GDDR6 determines whether this model matches your workload. It supports DirectX 12 and OpenGL 4.6 for modern titles and professional applications at up to 7680 x 4320 resolution. Verify your power supply provides the necessary connectors for a 2.7-slot card before purchase.

Questions about this item

What comes in the box with the ASUS Dual RTX 2080 and do I need to buy any cables or adapters separately?

The card includes one HDMI 2.0b port, three DisplayPort 1.4 ports and one USB Type-C connector. Cables for those ports are not supplied, so purchase the matching cables for your monitors separately.

Should I run the card in OC mode at 1830 MHz or Gaming mode at 1800 MHz for my build?

OC mode sets the boost clock to 1830 MHz for maximum frequency headroom, while Gaming mode targets 1800 MHz with a quieter fan profile. Choose OC mode if you prioritise peak clock speed and have adequate case airflow.

What does the 14000 MHz GDDR6 memory speed mean for 4K gaming on this 8 GB card?

The 14000 MHz effective clock on the 256-bit bus feeds the 2944 CUDA cores with high memory throughput, helping maintain frame rates at 7680 x 4320 resolution in memory-heavy titles.
