Conclusion
The NVIDIA GeForce RTX 4080 SUPER is NVIDIA’s new SUPER refresh at the upper end of the RTX 40 series family. This new entrant, announced at CES 2024, replaces the GeForce RTX 4080 at a new price point of $999 utilizing the full AD103 die specifications. 
In our testing today, we put the Founders Edition through its paces in many games against the AMD Radeon RX 7900 XTX and GeForce RTX 4080 to see where it sits in performance. We tested DLSS Upscaling, Ray Tracing, and Frame Generation performance. We focused on the 4K gameplay experience, and what you are able to achieve in terms of playable performance with the GeForce RTX 4080 SUPER.
Performance
In terms of ‘what’s playable’ though, the GeForce RTX 4080 SUPER is a very capable 4K gaming video card. It provides a playable gameplay experience in games at 4K. In Horizon Forbidden West the game is playable above 65FPS at 4K, and with DLSS Upscaling upwards to 90FPS average. Avatar: Frontiers of Pandora is slower at 4K, for this one turning on DLSS Upscaling will be needed for the smoothest gameplay at 4K. 
Alan Wake 2 is playable for the type of game it is at 4K, though DLSS Upscaling can help quite a bit. Assassin’s Creed Mirage is more than playable without Upscaling at 4K. Starfield is playable without Upscaling, but it certainly doesn’t hurt. Forspoken, Returnal, Chernobylite, and Dying Light 2 are also playable without Upscaling. Cyberpunk 2077 is right on the border, turning on DLSS Upscaling may be preferred.
When it comes to Ray Tracing, however, this is where performance jumps into unplayable territory for most games at 4K with the GeForce RTX 4080 SUPER. You are going to need to enable Quality DLSS at the very least, in most games, and in a few even Balanced DLSS such as in Cyberpunk or Alan Wake 2 with High Ray Tracing.
When comparing the GeForce RTX 4080 SUPER Founders Edition to the AMD Radeon RX 7900 XTX, things become interesting. There were a lot of games where the performance or experience at 4K was similar between them, especially if you enable Upscaling. When Upscaling is used, the performance evens out between them even more. However, there are some games that have more extremes one way or the other. 
We found Horizon Forbidden West heavily favors the Radeon RX 7900 XTX in performance. This game will just straight-up run better on the RX 7900 XTX without needing to enable Upscaling at 4K. Starfield was also a bit faster on the Radeon RX 7900 XTX, as was Returnal and Cyberpunk 2077. Where the Radeon RX 7900 XTX fell flat was in Ray Tracing performance, the GeForce RTX 4080 SUPER was faster if you wish to use Ray Tracing in games.
We were also impressed with the power draw on the GeForce RTX 4080 SUPER Founders Edition. Either through better binning or other reasons, our GeForce RTX 4080 SUPER Founders Edition consumed less power than the GeForce RTX 4080, and this was with higher shader counts, clocks, and memory clock. It is impressive, to get those single-digit performance uplifts, but utilize less power doing it.
Final Points
The performance summary for the GeForce RTX 4080 SUPER Founders Edition can be summed up simply, it provides the same gameplay performance and experience as the GeForce RTX 4080. While it has a 5% increase in CUDA Cores, a 5% increase in Tensor Cores, a 2% boost in clock speed, a 3% increase in memory clock, and a 3% increase in memory bandwidth, in terms of actual gameplay performance increase it’s between 1-3% over the GeForce RTX 4080. 
The main goal, and point, of the GeForce RTX 4080 SUPER is to fix the pricing on the GeForce RTX 4080 and bring it down to what it should have been at the start, $999. With this new price point, and basically the same performance as the GeForce RTX 4080, the GeForce RTX 4080 SUPER is the 4080 Done Right, finally.
