In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 3090 KFA2 EX Gamer White 24GB are significantly better than the Nvidia GeForce RTX 2060 3GB GDDR6.

The RTX 3090 has a 45 MHz higher core clock speed and 200 more Texture Mapping Units than the RTX 2060. This results in the RTX 3090 providing 287.4 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 RTX 3090 has a 45 MHz higher core clock speed and 49 more Render Output Units than the RTX 2060. This results in the RTX 3090 providing 71.2 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 RTX 3090 was released over a year more recently than the RTX 2060, and so the RTX 3090 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the RTX 2060.

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 21504 MB more video memory than the RTX 2060, 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 RTX 2060 has 288 GB/sec greater memory bandwidth than the RTX 3090, which means that the memory performance of the RTX 2060 is massively better than the RTX 3090.

The GeForce RTX 3090 KFA2 EX Gamer White 24GB has 10496 Shader Processing Units and the GeForce RTX 2060 3GB GDDR6 has 1920. However, the actual shader performance of the RTX 3090 is 18263 and the actual shader performance of the RTX 2060 is 3226. The RTX 3090 having 15037 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 2060.

The RTX 3090 transistor size technology is 4 nm (nanometers) smaller than the RTX 2060. This means that the RTX 3090 is expected to run very slightly cooler and achieve higher clock frequencies than the RTX 2060.

The GeForce RTX 3090 KFA2 EX Gamer White 24GB requires 350 Watts to run and the GeForce RTX 2060 3GB GDDR6 requires 150 Watts. We would recommend a PSU with at least 750 Watts for the RTX 3090 and a PSU with at least 450 Watts for the RTX 2060. The RTX 3090 requires 200 Watts more than the RTX 2060 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 2060.
