PowerColor Hellhound Radeon RX 7900 XTX, 24GB GDDR6, HDMI, 3x DP

Wie schlagen sich die neuen CPUs Ryzen 5 9600X und Ryzen 7 9700X im Gaming auf einer Grafikkarte vom Typ Radeon RX 7900 XTX im Vergleich zur GeForce RTX 4090? Wie reagieren die CPUs auf schnelleren Speicher bis hinauf zu DDR5-8000 in Spielen? Der Test liefert die Antworten.

Back in December when I first took a look at the RX 7900 XTX reference card I was impressed with its performance, especially when compared with the RTX 4080 from Nvidia and that hasn’t changed at all this time around with the Hellhound RX 7900 XTX. The 1080p performance and a lot of the 1440p performance is fast enough that a lot of our in-game tests are CPU limited even with the 13900K on our test bench. 4k performance looks great as well and in most tests, the Hellhound RX 7900 XTX outperforms the RTX 4080. The one big exception is in tests like 3DMark Speedway which uses ray tracing. The Hellhound RX 7900 XTX just improves on that slightly with its overclock, but if I’m being honest I figured a card with a name as cool as Hellhound would have had a bigger overclock it is just 26 MHz over the clock speed of the reference 7900 XTX. They make up for that with the cooling, the Hellhound has a monster cooler and it is extremely capable. The base fan profile however leans a little towards keeping things quiet and it does run extremely quiet when under load. Cranking the fans up has it performing well above what the reference card did. With the stock fan profile however, the GPU hotspot does still run hot but with the fans cranked up that did drop so a little tweaking on the fan profile could find a happy medium there.

The PowerColor Hellhound RX 7900 XTX Spectral White boasts an efficient cooling solution that allows for additional overclocking potential with minimal effort. Further, fine-tuning will unlock even greater performance. The increased power consumption is significant, reaching 420 of total board power (peak), but the card remains impressively quiet and cools effectively.

Before we get into the nitty gritty of the PowerColour RX 7900 XTX Hellhound, take a close look at the picture above. The Hellhound is a white card, but unlike most of the modern 'white' hardware, there isn't swathes of silver mucking up the aesthetic. Similarly the clear fan blades really help the lighting pop, and that is aided by the short fan shroud which lets the lighting bleed into the heatsink. Lastly the Hellhound logo surround on the backplate also lights up. Clearly PowerColor have put a lot of thought into the Hellhound, rather than merely spraying the black bits white and calling it a day. They deserve some brownie points for this alone, and that's before we've got into the performance and thermal side of things.
