No card comes with as much expectation as the Nvidia GeForce RTX 3090. Being the sole replacement for two heavy hitters from the last generation, Nvidia Titan RTX and the RTX 2080 Ti, is no easy feat as those are some big shoes to fill.
The good news is the “BFGPU” hiding behind the enormous heatsink is more than capable of doing heavy 3D rendering and gaming, due to its 24GB of GDDR6X memory. It’s also powerful enough to run 8K gaming at 60 fps, although the performance there still comes with some mixed results. As this generation’s flagship card, the Nvidia GeForce RTX 3090 reigns supreme over everything else available in the market.
Who said that the RTX 3090 is meant to replace the Titan RTX? It has been expressly said that the RTX 3090 is not meant to be the Titan replacement, its not "the same as Titan". A Titan has a lot more driver optimizations for specific use cases, and those haven't been enabled on RTX 3090, and probably will never be, as there for sure will be another Titan 30 series card. The 3090 is meant to be the ultimate prosumer card, not a workstation RTX Titan replacement. I think it has been stated in the tech press and by some Nvidia officials too, multiple times.
