In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition are marginally better than the Nvidia GeForce GTX 1080 MSI Gaming X 8GB Edition.

The GTX 1080 has a 76 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 1080. This results in the GTX 1080 providing 12.1 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 GTX 1080 has a 76 MHz higher core clock speed than the GTX 1080 and the same number of Render Output Units. This results in the GTX 1080 providing 4.9 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition and the GeForce GTX 1080 MSI Gaming X 8GB Edition were released at the same time, so are likely to be quite similar.

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 GTX 1080 Asus ROG Strix Gaming OC 8GB Edition and the GeForce GTX 1080 MSI Gaming X 8GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 1080 has 3 GB/sec greater memory bandwidth than the GTX 1080, which means that the memory performance of the GTX 1080 is marginally better than the GTX 1080.

Both the GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition and the GeForce GTX 1080 MSI Gaming X 8GB Edition have 2560 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the GTX 1080 has 12.1 GTexel/s better Texture Fill Rate and 4.9 GPixel/s better Pixel Fill Rate, but the GTX 1080 has 3 GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the GTX 1080 takes the edge.

The GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition requires 300 Watts to run and the GeForce GTX 1080 MSI Gaming X 8GB Edition requires 180 Watts. We would recommend a PSU with at least 500 Watts for the GTX 1080 and a PSU with at least 500 Watts for the GTX 1080. The GTX 1080 requires 120 Watts more than the GTX 1080 to run. The difference is significant enough that the GTX 1080 may have an adverse affect on your yearly electricity bills in comparison to the GTX 1080.
