Reviews of the GeForce RTX 3090 may still be under NDA according to Videocardz, but MKBHD and Linus Tech Tips have offered some initial gaming impressions of NVIDIA's latest card at 8K. The RTX 3090 has been shown to offer as little as 5% FPS improvements over the RX 3080 at 4K, but the triple-slot card appears to be capable of (mostly) 60 FPS gaming at 8K.
Neither Marques Brownlee nor Linus Sebastian offered a breakdown of FPS scores, but the former at least showed a consistent FPS counter during his video. It seems that all RTX 3090 review units will be paired with the Intel Core i9-10900K, for reference, which clocks up to 5.3 GHz on a single core. Brownlee also confirmed that he tested the RTX 3090 in a Maingear F131 that had been paired with 32 GB of RAM.
From the two videos, it seems that the RTX 3090 can maintain 60 FPS at 8K in games like Doom Eternal. Sebastian stressed that he tested the game locked to 60 FPS with HDR enabled, while Death Stranding looked smooth on High/Very High graphics with DLSS Ultra Performance enabled. It is a similar story in Forza Horizon 4, although Brownlee notes that Playground Games and Turn 10 Studio have pre-rendered content at 30 FPS at possibly 1440p, not 8K/60 FPS.
In Brownlee's video, the RTX 3090 maintained 60 FPS during the Autumn opening sequence of Forza Horizon 4, which continued into the Winter sequence with a few drops as low as 55 FPS. GPU usage seemed to hit 95% at this point, but the Spring sequence pushed the card harder, resulting in a low of 47 FPS and fluctuations between 49-57 FPS in some parts with occasional peaks of 60 FPS.
The performance of the RTX 3090 in Control is more interesting, though. The Founders Edition maintained around 50 FPS in 8K with DLSS, and VSync enabled on a Custom graphics preset. However, these framerates were only achievable with the render resolution set to 1440p. Increasing the render resolution to 4K caused framerates to drop to 32-36 FPS, while a render resolution of 5K resulted in framerates of 20/21 FPS. We are yet to see RTX 3080 8K benchmarks, but it will be interesting to see the difference between NVIDIA's two premium cards. According to TweakTown, these benchmarks should start arriving within the next month, probably after the official release of the RTX 3090 Founders Edition.
