GeForce RTX 4090 game performance estimates leave RTX 3090 and RX 6900 XT in the dust as Doom Eternal prediction hits 400 FPS at 4K ultra

An interesting comparison video posted by iVadim has pitted the still unofficial GeForce RTX 4090 against the RTX 3090 and Radeon RX 6900 XT. By using previous rumors and leaks based on the upcoming Lovelace cards, the bar has been set with the RTX 4090 predicted to offer “60-80% more FPS”, which is something similar to what has been claimed by other commenters. For instance, the noted tipster Greymon55 simply stated “3090 double performance”. It’s a heady promise for gamers, and if sufficient units are in place at launch time, it will be a welcome relief for those who manage to snap up a mighty RTX 40 series card after maybe missing out on Ampere.

In Doom Eternal (4K ultra), the average rate for the RTX 4090 is estimated at a whopping 400 FPS, which is +81.82% over the RTX 3090 (220 FPS) and an astonishing +106.19% beyond the 6900 XT (194 FPS). Cyberpunk 2077 is not an issue for the RTX 4090 either, with the next-gen card churning out an average rate of 95 FPS at 4K high quality settings. The previous-generation Ampere board is not bad on 53 FPS while the AMD premium card stutters a little on 48 FPS, but these results leave the Lovelace board at +79.25% and +97.92 ahead, respectively. As mentioned above, the GeForce RTX 4090 with its alleged 18,432 CUDA cores and 66.4 TFLOPs performance power (FP32 at 1.8 GHz) can smash out 106 FPS during Assassin’s Creed Valhalla on 4K and in ultra-high-quality settings.

Of course, not all gamers will care about theoretical 4K rates, especially if they are utilizing a monitor with a fast refresh rate (144 Hz or 240 Hz) that supports 1440p output. So, the comparison video has a look at what the GeForce RTX 4090 could potentially offer at this more realistic level. While Assassin’s Creed Valhalla “only” hits 151 FPS ultra on the Lovelace card, which is +79.76% above the RTX 3090 (84 FPS) and +43.81% beyond the 6900 XT (105 FPS), it would still be enough to max out a 144 Hz-capable monitor. The RTX 4090 predictions cannot cross the 200 FPS barrier in newer GPU-hungry games that are mentioned in the 1440p part of the comparison, but the card easily chews up older games such as Shadow of the Tomb Raider (313 FPS average on highest quality) and Death Stranding (334 FPS very high).
