In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 2080 Ti SLI are massively better than the AMD Radeon R7 250X PowerColor 1GB Edition.

The RTX 2080 Ti has a 350 MHz higher core clock speed and 232 more Texture Mapping Units than the R7 250X. This results in the RTX 2080 Ti providing 327.2 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 RTX 2080 Ti has a 350 MHz higher core clock speed and 72 more Render Output Units than the R7 250X. This results in the RTX 2080 Ti providing 102.8 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 RTX 2080 Ti was released over three years more recently than the R7 250X, and so the RTX 2080 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the R7 250X when running the latest games.

The RTX 2080 Ti has 10240 MB more video memory than the R7 250X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RTX 2080 Ti also has superior memory performance overall.

The RTX 2080 Ti has 544 GB/sec greater memory bandwidth than the R7 250X, which means that the memory performance of the RTX 2080 Ti is massively better than the R7 250X.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the Radeon R7 250X PowerColor 1GB Edition has 640. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the R7 250X is 544. The RTX 2080 Ti having 6572 better shader performance and an altogether better performance when taking into account other relevant data means that the RTX 2080 Ti delivers a massively smoother and more efficient experience when processing graphical data than the R7 250X.

The RTX 2080 Ti transistor size technology is 16 nm (nanometers) smaller than the R7 250X. This means that the RTX 2080 Ti is expected to run slightly cooler and achieve higher clock frequencies than the R7 250X.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the Radeon R7 250X PowerColor 1GB Edition requires 80 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti and a PSU with at least 450 Watts for the R7 250X. The RTX 2080 Ti requires 180 Watts more than the R7 250X to run. The difference is significant enough that the RTX 2080 Ti may have an adverse affect on your yearly electricity bills in comparison to the R7 250X.
