In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 3090 KFA2 EX Gamer White 24GB are very slightly better than the Nvidia GeForce RTX 3070 Ti.

The RTX 3070 Ti has a 14 MHz higher core clock speed than the RTX 3090, but the RTX 3090 has 108 more Texture Mapping Units than the RTX 3070 Ti. As a result, the RTX 3090 exhibits a 149.3 GTexel/s better Texture Fill Rate than the RTX 3070 Ti. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RTX 3070 Ti has a 14 MHz higher core clock speed than the RTX 3090, but the RTX 3090 has 32 more Render Output Units than the RTX 3070 Ti. As a result, the RTX 3090 exhibits a 44.3 GPixel/s better Pixel Fill Rate than the RTX 3070 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RTX 3070 Ti was released less than a year after the RTX 3090, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The RTX 3090 has 8192 MB more video memory than the RTX 3070 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RTX 3090 also has superior memory performance overall.

The memory bandwidth of the GeForce RTX 3090 KFA2 EX Gamer White 24GB and the GeForce RTX 3070 Ti are the same, which means the RTX 3090 and the RTX 3070 Ti have equal limitations when it comes to graphical data transfer.

The GeForce RTX 3090 KFA2 EX Gamer White 24GB has 10496 Shader Processing Units and the GeForce RTX 3070 Ti has 3072. However, the actual shader performance of the RTX 3090 is 18263 and the actual shader performance of the RTX 3070 Ti is 5751. The RTX 3090 having 12512 better shader performance and an altogether better performance when taking into account other relevant data means that the RTX 3090 delivers a massively smoother and more efficient experience when processing graphical data than the RTX 3070 Ti.

The RTX 3070 Ti transistor size technology is 1 nm (nanometers) smaller than the RTX 3090. This means that the RTX 3070 Ti is expected to run very slightly cooler and achieve higher clock frequencies than the RTX 3090.

The GeForce RTX 3090 KFA2 EX Gamer White 24GB requires 350 Watts to run and the GeForce RTX 3070 Ti requires 250 Watts. We would recommend a PSU with at least 750 Watts for the RTX 3090 and a PSU with at least 650 Watts for the RTX 3070 Ti. The RTX 3090 requires 100 Watts more than the RTX 3070 Ti to run. The difference is significant enough that the RTX 3090 may have an adverse affect on your yearly electricity bills in comparison to the RTX 3070 Ti.
