Test Configuration – Software

  • GeForce 526.98 drivers for the RTX 4090/4080 and 527.27 for the RTX 3080/3080 Ti.  Adrenalin 22.11.2 for the RX 6800 XT and 6900 XT, and press drivers for the RTX 7900 XTX.
  • High Quality, prefer maximum performance, single display, set in the Nvidia control panel.
  • High Quality textures, all optimizations off in the Adrenalin control panel
  • VSync is off in the control panel and disabled for each game

Overclocking, temperatures and noise

We spent little time overclocking the Hellhound RX 7900 XTX for this review as we encountered some unexpected results that require further investigation.  The card is very quiet and its fans never spin up even under a heavy load so as to be irritating or even noticeable.  It’s quieter than the Gigabyte 6900 XT or the RTX 3080 Ti.

The Hellhound RX 7900 XTX is factory clocked 30MHz higher than the reference version at 2330MHz using the OC BIOS.  According to its specifications, the Hellhound boost can clock up to 2565MHz out of the box. From our benching, we generally see it boosting even higher and it generally settles in above 2750MHz with peaks above 2780MHz.

The Hellhound temperatures stay in the low to mid-60s C with the fans quietly running well below 50% even using the OC BIOS under a full gaming load.  It is an exceptionally well-cooled and quiet card.

Let’s head to the performance charts to compare the performance of the Hellhound RX 7900 XTX with six other cards.
