In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675M SLI are very slightly better than the Nvidia GeForce GTX 670MX SLI.

The GTX 675M has a 20 MHz higher core clock speed than the GTX 670MX, but the GTX 670MX has 32 more Texture Mapping Units than the GTX 675M. As a result, the GTX 670MX exhibits a 16.6 GTexel/s better Texture Fill Rate than the GTX 675M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 675M has a 20 MHz higher core clock speed and 16 more Render Output Units than the GTX 670MX. This results in the GTX 675M providing 10.9 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 670MX was released less than a year after the GTX 675M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 670MX has 2048 MB more video memory than the GTX 675M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 675M has superior memory performance.

The GTX 675M has 57.6 GB/sec greater memory bandwidth than the GTX 670MX, which means that the memory performance of the GTX 675M is much better than the GTX 670MX.

The GeForce GTX 670MX SLI has 1920 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GTX 670MX is 1152 and the actual shader performance of the GTX 675M is 952. The GTX 670MX having 200 better shader performance is not particularly notable, as altogether the GTX 675M performs better when taking into account other relevant data.

The GTX 670MX transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 670MX is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 670MX SLI requires 150 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 50 Watts more than the GTX 670MX to run. The difference is significant enough that the GTX 675M may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 670MX.

GPU Mini Review

Mini ReviewGeForce GTX 670MX SLI is a solution of two GeForce GTX 670MX put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 670MX 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, is up to X% better than a single GeForce GTX 670MX 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 670MX.
Even the most demanding games will run at the highest settings.
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.
