In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 680M SLI are noticeably better than the Nvidia GeForce GTX 675M SLI.

The GTX 680M has a 100 MHz higher core clock speed and 96 more Texture Mapping Units than the GTX 675M. This results in the GTX 680M providing 81.9 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 680M has a 100 MHz higher core clock speed than the GTX 675M and the same number of Render Output Units. This results in the GTX 680M providing 6.4 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 680M 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.

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 675M SLI and the GeForce GTX 680M SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 680M has 38.4 GB/sec greater memory bandwidth than the GTX 675M, which means that the memory performance of the GTX 680M is noticeably better than the GTX 675M.

The GeForce GTX 675M SLI has 768 Shader Processing Units and the GeForce GTX 680M SLI has 2688. However, the actual shader performance of the GTX 675M is 952 and the actual shader performance of the GTX 680M is 1935. The GTX 680M having 983 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 680M delivers a massively smoother and more efficient experience when processing graphical data than the GTX 675M.

The GTX 680M transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 680M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 675M SLI requires 200 Watts to run and the GeForce GTX 680M SLI requires 200 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewGeForce 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.
GeForce GTX 680M SLI is a solution of two GeForce GTX 680M put together using NVIDIA'S SLI technology.
As it's known, GeForce GTX 680M is based on the Kepler GK104 Core, featuring 1344 Shading Units but with lower clock frequencies putting its performance at level with a desktop GeForce GTX 660.
As usual, SLI relies a lot on proper driver support. Benchmarks indicate the performance is overall, about 45% better than a single GeForce GTX 680M performing by itself but at times it performed worse than a single GeForce GTX 680M.
