In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980MX 8GB are significantly better than the Nvidia GeForce GTX 675M SLI.

The GTX 980MX has a 418 MHz higher core clock speed but 24 fewer Texture Mapping Units than the GTX 675M. The lower TMU count doesn't matter, though, as altogether the GTX 980MX manages to provide 28.6 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 980MX has a 418 MHz higher core clock speed than the GTX 675M and the same number of Render Output Units. This results in the GTX 980MX providing 26.7 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 GTX 980MX was released over three years more recently than the GTX 675M, and so the GTX 980MX is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 675M 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 GTX 980MX has 4096 MB more video memory than the GTX 675M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 980MX also has superior memory performance overall.

The GTX 675M has 31.6 GB/sec greater memory bandwidth than the GTX 980MX, which means that the memory performance of the GTX 675M is noticeably better than the GTX 980MX.

The GeForce GTX 980MX 8GB has 1664 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GTX 980MX is 2534 and the actual shader performance of the GTX 675M is 952. The GTX 980MX having 1582 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980MX delivers a significantly smoother and more efficient experience when processing graphical data than the GTX 675M.

The GTX 980MX transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 980MX is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 980MX 8GB requires 122 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 78 Watts more than the GTX 980MX to run. The difference is significant enough that the GTX 675M may have an adverse affect on your yearly electricity bills in comparison to the GTX 980MX.

System Suggestions
GeForce GTX 980MX 8GB is best suited for resolutions up to and including 1920x1080. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
GeForce GTX 675M SLI is a solution of two GeForce GTX 675M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 675M to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, about 35% better than a single GeForce GTX 675M performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 675M.
Even the most demanding games will run at the highest settings.
