ASUS Dual GeForce RTX 2080 8GB GDDR6

The ASUS Dual GeForce RTX 2080 is a graphics card built on the NVIDIA Turing architecture with 8GB of GDDR6 memory on a 256-bit interface. It connects via PCI Express 3.0 and delivers a boost clock of 1830 MHz in OC mode and 1800 MHz in Gaming mode. The card features 2944 CUDA cores for parallel compute workloads.

Suitable for 4K gaming and multi-monitor setups

This model suits enthusiasts targeting high-refresh 1440p or entry-level 4K gaming across up to four displays using HDMI 2.0b and three DisplayPort 1.4 outputs. It supports SLI for multi-GPU scaling in compatible titles. Builders needing PCIe 4.0 bandwidth, newer RTX 30-series features, or a smaller dual-slot form factor should consider other options.

8GB 256-bit GDDR6 memory decides fit

The 8GB GDDR6 frame buffer running at 14000 MHz effective clock determines whether this card meets your texture and resolution demands. At 7680 x 4320 maximum resolution, it handles 4K assets but may limit heavy 4K texture packs or professional 8K workflows. Verify your VRAM requirements before purchase.

Questions about this item

How does the 1830 MHz OC boost clock behave once the card is installed in a system?

The GPU can reach 1830 MHz in OC mode when thermal and power headroom allow; actual sustained clocks depend on case airflow and workload.

What does the PCI Express 3.0 interface mean for bandwidth on this RTX 2080?

The card runs on a PCIe 3.0 link, so its host bandwidth is limited to the 3.0 specification rather than newer 4.0 or 5.0 speeds.

What physical space and power connectors does the Dual RTX 2080 need to fit and run?

The Dual series uses a two-slot, dual-fan design that fits standard ATX cases and draws power through an 8-pin and a 6-pin PCIe connector.
