The Hellhound RX 7900 XTX versus the RTX 4080

These competing cards are put to the test using 50 VR and PC games.

The AMD $999 Hellhound RX 7900 XTX arrived at JPR’s sister site BTR for evaluation last week from PowerColor, ready to prove itself. Since then, Babel TechReviews has been comparing it against Nvidia’s new $1,199 RTX 4080 Founders Edition (FE) and $1,599 RTX 4090 FE, plus five additional top cards. The group’s focus has been on raw performance by benchmarking 42 PC and 10 VR games, in addition to GPGPU, workstation, SPEC, and synthetic benchmarks.

BTR will also compare the performance of these three new competing cards with the RX 6900 XT and RX 6800 XT reference editions and their competitors, the RTX 3080 Ti and RTX 3080 FE.

Features & Specifications

Although launched at reference $999 XTX pricing, the Hellhound RX 7900 XTX has its factory game clock set 30MHz higher than the reference version’s 2,300MHz. According to PowerColor specifications, the Hellhound RX 7900 XTX can boost its game clock to 2,330MHz (2,270MHz silent) with the OC BIOS. The game clock is the expected GPU clock while running average high-load gaming scenarios with a regular non-overclocked total graphics usage situation. However, the GPU boost clock can reach as high as 2,525MHz—25MHz higher than reference—by using the OC BIOS, and BTR will test this.

Meanwhile, Mark Poppin from JPR’s sister site Babel Tech Reviews stacks the new RDNA 3-based RX 7900 XTX against seven other graphics add-in boards and runs them through over 50 games and benchmarks. Read his latest review on the PowerColor Hellhound RX 7900 XTX.
