Dual Radeon RX 7800 XT 16 GB

The ASUS Dual Radeon RX 7800 XT ships with 16 GB of GDDR6 memory on a 256-bit bus and a boost clock of 2520 MHz. It targets gamers and creators who want 1440p or 4K performance on a PCIe 4.0 platform.

PCIe 4.0 x16 slot and 750 W PSU

Verify that your motherboard provides a full-length PCIe 4.0 x16 slot and that the case can clear a 280 mm card occupying 2.47 slots. The maker recommends a 750 W power supply to handle the 263 W board power.

Axial-tech fans and protective backplate

Two axial-tech fans with dual ball bearings push air through a heatsink while a metal backplate stiffens the PCB. Under typical gaming loads the cooler keeps thermals in check and noise moderate without exotic measures.

Questions about this item

Does the DUAL-RX7800XT-O16G come with power cables or adapters in the box?

The card draws up to 263W and needs a 750W PSU with native PCIe power connectors; no cables or adapters are included.

Should I pick the OC mode at 2520 MHz or stay at the default 2475 MHz core clock?

The OC mode raises the boost clock to 2520 MHz for extra performance; the default 2475 MHz runs cooler and quieter if you prefer lower thermals.

What does the 16 GB GDDR6 on a 256-bit bus actually deliver for 4K gaming?

The 16 GB frame buffer and 256-bit interface keep high-resolution textures resident, so 4K at 7680 x 4320 stays smooth without swapping to system memory.
