In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 860M 2GB SLI are noticeably better than the Nvidia GeForce GTX 675M SLI.

The GTX 860M has a 409 MHz higher core clock speed but 48 fewer Texture Mapping Units than the GTX 675M. The lower TMU count doesn't matter, though, as altogether the GTX 860M manages to provide 2.9 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 860M has a 409 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 32 more Render Output Units than the GTX 860M. As a result, the GTX 675M exhibits a 6.8 GPixel/s better Pixel Fill Rate than the GTX 860M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 860M was released over a year more recently than the GTX 675M, and so the GTX 860M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 675M.

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 860M 2GB SLI and the GeForce GTX 675M 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 675M has 31.6 GB/sec greater memory bandwidth than the GTX 860M, which means that the memory performance of the GTX 675M is noticeably better than the GTX 860M.

The GeForce GTX 860M 2GB SLI has 1280 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GTX 860M is 1896 and the actual shader performance of the GTX 675M is 952. The GTX 860M having 944 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 860M delivers a marginally smoother and more efficient experience when processing graphical data than the GTX 675M.

The GTX 860M transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 860M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 860M 2GB SLI requires 120 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 80 Watts more than the GTX 860M 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 860M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 860M 2GB SLI is a solution of two GeForce GTX 860M 2GB put together using NVIDIA's SLI technology.

Check the Page of [GeForce GTX 860M 2GB]( to know more about its Architecture.

The Central Unit of each GPU runs at 1029MHz and goes up to 1097MHz, in Turbo Mode.

Memory: Speed
Each GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1253MHz.

Memory: Frame Buffer
Each GPU can fill up a Memory Pool of up to 2GB.

Power Consumption
Power Consumption is around 120W.

Gaming benchmarks prove that at 1920x1080, the best suited resolution, GeForce GTX 860M 2GB SLI is around 20% faster than a Single GeForce GTX 880M.

System Suggestions
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.
