Built for 1440p and 4K gaming

The Sapphire ONCE HUMAN RX 7800 XT delivers 16 GB of GDDR6 memory on a 256-bit bus, driven by 3840 stream processors and a 64 MB Infinity Cache. Game clock runs at 2169 MHz with an acceleration frequency of 2475 MHz, while memory operates at 19.5 Gbps. The RDNA 3 architecture is built on a 5 nm graphics compute die and 6 nm memory cache dies.

Triple-fan cooler and dual 8-pin power

A three-fan cooler keeps the 320 mm long card within thermal limits, drawing power from two 8-pin connectors and requiring a 700 W supply. The board fits a standard dual-slot footprint of 129 mm height and 53 mm depth. Display outputs comprise two HDMI ports and two DisplayPort 2.1 connectors, supporting up to 7680 x 4320 resolution across four simultaneous screens. PCIe 4.0 provides the system link.

Step up from 10 GB or 12 GB mid-range cards

The 16 GB frame buffer removes VRAM bottlenecks in modern titles and texture-heavy workloads that limit 10 GB or 12 GB models. The 256-bit bus and 64 MB Infinity Cache sustain bandwidth for high-refresh 1440p play and entry 4K. If your current card hits memory capacity walls before GPU utilisation peaks, this upgrade restores headroom.

Questions about this item

Will the 2475 MHz boost clock hold under sustained load or will the card throttle?

The GPU runs at a 2169 MHz gaming frequency and can reach 2475 MHz acceleration frequency; sustained clocks depend on case airflow and the 700 W power supply delivering stable current to the dual 8-pin connectors.

How loud and hot does the triple-fan cooler get during all-day gaming sessions?

The three-town decisive movement fan design moves air across a 320 mm long heatsink; noise and temperature will vary with chassis ventilation but the card is built to exhaust heat out the rear I/O bracket.

My PSU only has a single 8-pin PCIe cable — do I need a second one or an adapter?

The card requires two 8-pin power connectors, so a power supply with at least two native 8-pin PCIe cables (or a quality dual 8-pin adapter on a 700 W unit) is necessary for stable operation.
