ASUS Radeon RX 7900 XTX

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.

Welche Vor- oder Nachteile bieten Custom-Designs der AMD Radeon RX 7900 XTX mit Navi-31-GPU im Vergleich zum Referenzdesign in Bezug auf Leistung, Lautstärke, Temperaturen und Verbrauch? ComputerBase hat mit Asus TUF Gaming OC, PowerColor Hellhound, Sapphire Nitro+ und XFX Merc 310 die Probe aufs Exempel gemacht.

AMD's new RNDA3 architecture brings with it the world's first GPU based on chiplet technology. Why is that a big deal you ask? Making large chips is expensive, more expensive than making several small chips. AMD realized that years ago and built their Ryzen CPUs using the chiplet approach, which is the foundation for the company's tremendous comeback in the CPU space. Team Red is betting that the same can happen in the GPU world, and today we're testing their first products built using that philosophy. Using chiplets gives another major advantage—you can combine multiple production processes. For the case of the Navi 31 GPU that powers the Radeon RX 7900 Series, the central compute die is fabricated on TSMC's leading 5 nanometer node, because efficiency greatly matters for its design. On the other hand, the memory-cache dies don't put out as much heat, and contain analog technology, which doesn't scale as well with process size. That's why AMD decided to build those with 6 nanometer tech, making them cheaper to produce.

ASUS hit the nail on the head with the TUF; it has the most excellent acoustics we have tried with an XTX and keeps its cool while running under load. We think the OC model is understated compared to its rivals, as the additional performance is merely 2~3% at best. The final result is a proper-looking, excellent-performing product. I do seem to like the XTX much better than the XT. It's hard to explain why that to a 10~15% performance e differential can make so much of a perceptible difference, though. The Radeon RX 7900 XTX. It positions itself in that RTX 4080 marker of performer better, for 100 USD more than the regular 7900 XT model. The flagship GPU of AMD's rDNA3 is adequately competitive with NVIDIA's 4080 and often even 4090. When looking at raw shader performance, it's plenty fast ... often passing the more expensive GeForce RTX 4080. The Radeon RX 7900 Series has two Achilles' heels.
