ASUS ROG Strix GeForce RTX 4090 White Edition 24GB graphics card

White Edition ROG Strix RTX 4090

The ASUS ROG Strix GeForce RTX 4090 White Edition is a high-end graphics card built on the NVIDIA Ada Lovelace architecture. It targets enthusiasts and creators who need 24GB of GDDR6X memory on a 384-bit interface for 4K gaming and professional rendering workloads. The card connects through a PCI Express 4.0 slot and provides two HDMI 2.1a ports plus three DisplayPort 1.4a outputs for up to four simultaneous displays.

Sustained-load thermal behaviour

A patented vapor chamber with a milled heatspreader sits above the GPU to spread heat quickly across a massive fin array. Three Axial-tech fans scaled up for 23% more airflow push air through the 3.5-slot heatsink while a diecast shroud, frame and vented backplate add rigidity and extra exhaust paths. Digital power control with high-current power stages and 15K capacitors delivers stable current during extended compute or gaming sessions.

24GB GDDR6X frame buffer

The single specification that determines suitability is the 24GB GDDR6X memory running at 21 Gbps across a 384-bit bus. This capacity and bandwidth combination lets the 16384 CUDA cores hold entire 4K texture sets and large scene data without paging to system RAM. If your workload fits inside 24GB the card will maintain full throughput; if it exceeds that limit you will need a different solution.
