In the elite graphics card segment, NVIDIA has long established itself as the key player. From the legendary GTX 1080 Ti to the impressive RTX 3090, each generation has strengthened its dominance, leaving AMD a secondary role in the very high-end. But with the RDNA 3 , the red camp is back on the attack and clearly displays its ambitions with the Radeon RX 7900 XTX .
Far from settling for outsider status, this card aims to redistribute the cards. We've put two iconic references under the microscope: the ASUS TUF Gaming Radeon RX 7900 XTX OC Edition and the Sapphire Nitro+ Radeon RX 7900 XTX Vapor-X , positioned against the heavyweights that are the GeForce RTX 4080 Super and RTX 4090 . Raw performance, energy efficiency, thermal management and software ecosystem: everything is analyzed to see if AMD has finally found the weapon capable of seducing the most demanding gamers.

Datasheet: RDNA 3 architecture put to the test
At the heart of the Radeon RX 7900 XTX is the RDNA 3 , a real leap forward for AMD. Based on the Navi 31 and its 6144 stream processors chiplet design that separates the computing core (GCD) from the memory modules (MCD). The result: increased transistor density and better energy efficiency, a change in philosophy that brings AMD closer to what the CPU world is already doing.
On the memory side, the RX 7900 XTX hits hard with 24 GB of GDDR6 on a 384-bit bus . A choice that ensures excellent longevity, especially for 4K gaming with ultra textures and ray tracing enabled . Compared to the RTX 4080 Super and its 16 GB of GDDR6X, this is an undeniable advantage; and compared to the RTX 4090 , it is on equal terms in terms of VRAM capacity.
The frequencies depend on the custom models: the Sapphire Nitro+ climbs up to 2680 MHz in boost , while the ASUS TUF reaches 2615 MHz in OC mode , values well beyond the reference specifications.
The connectivity is up to date with three DisplayPort 2.1 and one HDMI 2.1 , enough to take advantage of 4K (and even 8K) screens with very high refresh rates. A detail that can make the difference for gamers equipped with the latest premium monitors.
Finally, cooling is one of the key points. The Sapphire Nitro+ relies on its Vapor-X with vapor chamber, capable of efficiently evacuating heat even under full load. The ASUS TUF , true to its reputation for robustness, incorporates a massive heat sink and three optimized axial fans, guaranteeing both low temperatures and appreciable operating silence .
Gaming Performance: The 4K Battle
In practice, the Radeon RX 7900 XTX is clearly aimed at gamers aiming for 4K without compromise. In rasterization (classic rendering without ray tracing), it positions itself neck and neck with the GeForce RTX 4080 Super . In many titles, the gaps are minimal, and depending on the optimizations of the game engines, AMD even manages to take the lead.
The story changes as soon as you enable ray tracing . Thanks to its 3rd generation RT cores , NVIDIA maintains a lead. The RTX 4080 Super remains more consistent than the RX 7900 XTX in this area, and the RTX 4090 , with its raw power, imposes an even greater gap. At AMD, the impact of ray tracing remains noticeable, even if software optimizations and driver updates gradually narrow the gap.
In terms of power consumption , the RX 7900 XTX is not the most economical. With a TDP of 355 W in the reference version and more than 400 W for overclocked models, it requires a solid power supply. Fortunately, custom versions like the Sapphire Nitro+ Vapor-X and the ASUS TUF Gaming more than compensate with efficient cooling systems: the Nitro+ keeps temperatures below 60 ° C under load , while the TUF displays similar results with a contained noise level. In comparison, the RTX 4080 Super , more energy-efficient, can be even more discreet in operation.
Advantages and disadvantages: technologies and ecosystem
Beyond pure benchmarks, the choice between AMD and NVIDIA also hinges on the technologies that revolve around GPUs. And this is often where the differences become more pronounced.
✅ AMD's strengths
An unbeatable price/performance ratio : in 2025, the Radeon RX 7900 XTX remains significantly more affordable than the RTX 4080 Super , and light years ahead of the stratospheric price of the RTX 4090. For those who prefer rasterization , the return per euro invested is clearly in AMD's favor.
24GB of GDDR6 VRAM : a generous amount that ensures excellent durability . With modern games increasingly demanding video memory, especially in 4K with ultra textures, this leeway becomes a real guarantee of longevity.
FidelityFX Super Resolution (FSR 3) : AMD's in-house upscaling has come a long way. Open, compatible with a wide range of GPUs (including NVIDIA), it allows you to boost FPS without being limited to a single brand. With Frame Generation , it directly competes with DLSS, although the quality still varies depending on the game.
✅ NVIDIA's strengths
More advanced ray tracing : With its 3rd generation RT cores , NVIDIA stays ahead of the curve. Optimized games run better, and the gap remains clear when ray tracing is enabled.
DLSS 3.5 and Frame Generation : arguably the most advanced technology on the market. Version 3.5 introduces Ray Reconstruction , which further improves rendering quality. Combined with frame generation, it offers exemplary fluidity , especially in 4K with ray tracing.
A robust software ecosystem : NVIDIA isn't just about gaming. With the NVIDIA Studio for creators (optimized drivers for 3D, video editing, etc.) and NVIDIA Broadcast for streaming (noise reduction, background blur, etc.), the company offers a comprehensive software universe renowned for its stability .
👉 In summary: AMD seduces with its quality/price ratio and its generous VRAM , where NVIDIA keeps the technological advantage with its tools and its more mature ray tracing .
Value for money and positioning
In the high-end arena, the Radeon RX 7900 XTX stands out as the champion of performance/price ratio . In 2025, its average price will be under €1,200 , while the RTX 4080 Super will be close to €1,400 and the RTX 4090 will soar above €2,000 .
For those aiming for smooth 4K without breaking the bank, AMD's card appears to be the most rational option. While it lags behind in ray tracing , this remains a secondary use for the majority of gamers. In practice, the gaming experience remains solid and durable thanks to its 24 GB of VRAM .
High-end custom versions like the Sapphire Nitro+ and ASUS TUF Gaming justify a slightly higher price: boosted frequencies, reinforced cooling and a robust chassis provide an additional margin of comfort compared to the reference model.
👉 In short, the RX 7900 XTX ticks all the boxes for demanding gamers who want to enjoy the best return per euro invested in 4K.
