ASUS PROART-RTX4080-O16G graphics card 16GB GDDR6X

ProArt GeForce RTX 4080 16 GB creator card

The ASUS ProArt GeForce RTX 4080 ships with 16 GB of GDDR6X memory on a 256-bit bus and a PCI Express 4.0 interface. It targets creative professionals who need stable compute for rendering, video editing and 3D workloads. The triple-fan cooler uses Axial-tech fans scaled for 21% more airflow and dual ball bearings. A 2.5-slot form factor keeps case compatibility broad while maintaining thermal headroom.

Sustained load thermal and acoustic behaviour

Under continuous load the card draws up to 320 W through a single 16-pin connector with a 750 W PSU recommended. Axial-tech fans and a vapour-chamber base keep the GPU near its 2595 MHz default boost clock without throttling. 0dB technology stops the fans completely during light tasks for silent operation. GPU Tweak III profiles let creators optimise cooling curves per application.

Upgrade path from prior workstation GPUs

The 16 GB frame buffer replaces earlier 8 GB or 12 GB workstation cards that hit VRAM limits in complex scenes. The jump is worth it when projects exceed 12 GB texture budgets or require 7680 x 4320 output over HDMI 2.1 or DisplayPort 1.4a. PCIe 4.0 and DirectX 12 Ultimate support modern creative pipelines without platform bottlenecks.
