In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 3090 are very slightly better than the Nvidia Titan RTX.

The GeForce RTX 3090 has a 50 MHz higher core clock speed and 32 more Texture Mapping Units than the Titan RTX. This results in the GeForce RTX 3090 providing 59.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce RTX 3090 has a 50 MHz higher core clock speed than the Titan RTX and the same number of Render Output Units. This results in the GeForce RTX 3090 providing 4.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce RTX 3090 was released over a year more recently than the Titan RTX, and so the GeForce RTX 3090 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Titan RTX.

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 GeForce RTX 3090 and the Titan RTX have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce RTX 3090 has 240 GB/sec greater memory bandwidth than the Titan RTX, which means that the memory performance of the GeForce RTX 3090 is massively better than the Titan RTX.

The GeForce RTX 3090 has 10496 Shader Processing Units and the Titan RTX has 4608. However, the actual shader performance of the GeForce RTX 3090 is 17843 and the actual shader performance of the Titan RTX is 8156. The GeForce RTX 3090 having 9687 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce RTX 3090 delivers a massively smoother and more efficient experience when processing graphical data than the Titan RTX.

The GeForce RTX 3090 transistor size technology is 4 nm (nanometers) smaller than the Titan RTX. This means that the GeForce RTX 3090 is expected to run very slightly cooler and achieve higher clock frequencies than the Titan RTX.

The GeForce RTX 3090 requires 350 Watts to run and the Titan RTX requires 280 Watts. We would recommend a PSU with at least 750 Watts for the GeForce RTX 3090 and a PSU with at least 650 Watts for the Titan RTX. The GeForce RTX 3090 requires 70 Watts more than the Titan RTX to run. The difference is significant enough that the GeForce RTX 3090 may have an adverse affect on your yearly electricity bills in comparison to the Titan RTX.
