Sapphire ONCE HUMAN RX 7800 XT 16GB

The Sapphire ONCE HUMAN RX 7800 XT 16GB is a desktop graphics card built on AMD RDNA 3 architecture. It targets gamers and creators who want high frame rates at 1440p or entry 4K. The GPU offers 3840 stream processors, 16 GB GDDR6 memory on a 256-bit bus and a game clock of 2169 MHz.

Power and space requirements

Your power supply must deliver at least 700 W and provide two 8-pin PCIe connectors. The card measures 320 x 129 x 53 mm, so verify that your case has enough length and height clearance. A PCIe 4.0 x16 slot is required and the motherboard BIOS should be current for full compatibility.

Display outputs and software

Two HDMI and two DisplayPort 2.1 connectors drive up to four monitors at a maximum resolution of 7680 x 4320. The bundled TriXX software lets you adjust clock speeds, fan curves and RGB lighting without third-party tools. AMD Adrenalin Edition drivers add features such as FidelityFX Super Resolution and Radeon Anti-Lag.

Questions about this item

What comes in the box with the Sapphire ONCE HUMAN RX 7800 XT 16G D6 and do I need to buy power cables separately?

The graphics card ships with the triple-fan cooler installed and two 8-pin power connectors on the board. Your power supply must provide both 8-pin cables; they are not included with the card.

The specs list 16 GB GDDR6 on a 256-bit bus at 19.5 Gbps — is there any other memory version of this model I should consider?

This specific ONCE HUMAN edition is only offered with 16 GB of GDDR6 memory running at 19.5 Gbps across a 256-bit interface; no alternative capacities or speeds exist for this model.

The boost clock is shown as 2475 MHz — what does that actually mean for frame rates in games at 1440p?

The 2475 MHz acceleration frequency is the peak single-core speed; sustained gaming clocks sit at 2169 MHz, and together with 3840 stream processors and 64 MB Infinity Cache the card targets high-refresh 1440p performance in modern titles.
