The Last Of Us

• Here, the RTX 3090 Ti got an average of 51 FPS while the RX 7900 XTX ran at a higher framerate of around 57 FPS, making it 11.1% better.
• The RTX 3090 Ti hit lower 1% lows than the RX 7900 XTX at 30 FPS vs the latter’s 48 FPS.

Hogwarts Legacy

• In Hogwarts Legacy, we saw that the RTX 3090 Ti achieved an average framerate of 69 FPS, whereas the RX 7900 XTX got an average of around 79 FPS – resulting in a 13.5% gap.
• 1% lows were once again worse on the RTX 3090 Ti, touching about 52 FPS, whereas the RX 7900 XTX almost ran at the magic 60 FPS number at 1% lows of 59 FPS.

Hitman 3

• This well-optimized benchmarking classic once again showed the RX 7900 XTX to be faster as it averaged 161 FPS, whereas the RTX 3090 Ti averaged 115 FPS – being 33.3% slower.
• The 1% lows also continued to show the RX to be faster, with a minimum framerate of 133 FPS, whereas the RTX 3090 Ti had worse 1% lows of 101 FPS.

Red Dead Redemption 2

• Here, the RTX 3090 Ti had an average framerate of around 84 FPS, whereas the RX 7900 XTX reached an average of 101 FPS, being 18.3% faster than its rival.
• The RTX 3090 had a minimum 1% low of around 67 FPS, whereas the RX 7900 XTX had noticeably fewer stutters with a minimum framerate of 80 FPS.

Remnant 2

• The Remnant 2 game ran 28.5% better on the RX 7900 XTX with a 64 FPS, compared to the rather disappointing average of 48 FPS supplied by the Nvidia card in our benchmarks.
• 1% lows faired no better on the older card at around 39 FPS, whereas the RX 7900 XTX had 1% lows hovering around 59 FPS.

Forza Horizon 5

• The RTX 3090 Ti obtained an average of 106 FPS, whereas we also saw that the RX 7900 XTX had a much higher average of 142 FPS, where it led with a 29% performance margin.
• 1% lows were almost the most different in this well-optimized title, with the RTX 3090 Ti getting 86 FPS, whereas the RX 7900 XTX got lows of around 113 FPS.

Microsoft Flight Simulator

• The RTX 3090 Ti finally achieved its first victory in MS Flight Sim 2020 it averaged 60 FPS, whereas the RX 7900 XTX had an average of 59 FPS, being only 1.6% behind.
• 1% lows were also just a frame apart, only the tow, with the RTX 3090 Ti getting a framerate of 47 FPS, whereas the RX 7900 XTX had a framerate of 46 FPS. 

Overall Gaming Performance

Observing the overall gaming performances of the two GPUs, the RX 7900 XTX was about 22% faster than the RTX, incorporating a better and smoother performance than its competitor in our benchmarks. This tilts the scales in favor of the AMD Radeon RX 7900XTX, declaring it the dominant GPU.

Overall Power Consumption

Moving onto the power draw, we witnessed the RX 7900 XTX being considerably more power efficient drawing around 20% lower than the RTX 3090 Ti at an average. The RTX 3090 Ti showed 0.17 frames/watt, whereas the RX 7900 XTX proved to be 47% more efficient with around 0.26 frames/watt.

Overall Thermal Efficiency

Speaking about the thermal levels, the RTX 3090 Ti ran comparatively cool. In contrast, the RX 7900 XTX was rather warm in our testing, getting an average peak temperature of around 64°C. Though the RX 7900 XTX ran hotter than the RTX 3090 Ti, temperatures were well within the safe range for both cards.

Price And Availability

Our research showed that the RTX 3090 Ti’s price has been increased by 10% from its MSRP. Whereas, the RX 7900 XTX’s base variants saw a price drop of 6.1% whereas its higher-end variants are being sold at a 4.8% higher rate as compared to its original launch price. All in all, the RX 7900 XTX is around 71.2% to 80.7% cheaper than the RTX 3090 Ti.

Conclusion – Which One Would We Recommend?

RX 7900 XTX: If you are all for relentless gaming and incredible power-packed in a GPU, we recommend you go for the RX 7900 XTX. It is the more powerful card with a 22% edge and has the same merits as the RTX 3090 Ti while improving on performance. It also draws almost half the power and is also extremely cheaper than its rival.

RTX 3090 Ti: The RTX 3090 Ti, on the other, hand not only underperformed, but it also showed high power consumption. Yes, it operated with lower temperatures but its over-the-top price point doesn’t justify its performance that’s why we don’t recommend the RTX 3090 Ti. 

The RX 7900 XTX is the most reasonable option to opt for in our opinion because of its high performance at a lower price based on our benchmark results. However, you are free to choose whichever GPU according to your budget and current requirements.
