In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670MX SLI are noticeably better than the Nvidia GeForce GTX 950M 2GB.

The GTX 950M has a 314 MHz higher core clock speed than the GTX 670MX, but the GTX 670MX has 120 more Texture Mapping Units than the GTX 950M. As a result, the GTX 670MX exhibits a 59.4 GTexel/s better Texture Fill Rate than the GTX 950M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 950M has a 314 MHz higher core clock speed than the GTX 670MX, but the GTX 670MX has 32 more Render Output Units than the GTX 950M. As a result, the GTX 670MX exhibits a 14.2 GPixel/s better Pixel Fill Rate than the GTX 950M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 950M was released over a year more recently than the GTX 670MX, and so the GTX 950M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 670MX.

The GTX 670MX has 4096 MB more video memory than the GTX 950M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 670MX also has superior memory performance overall.

The GTX 670MX has 54.4 GB/sec greater memory bandwidth than the GTX 950M, which means that the memory performance of the GTX 670MX is much better than the GTX 950M.

The GeForce GTX 950M 2GB has 640 Shader Processing Units and the GeForce GTX 670MX SLI has 1920. However, the actual shader performance of the GTX 950M is 858 and the actual shader performance of the GTX 670MX is 1152. The GTX 670MX having 294 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 670MX delivers a massively smoother and more efficient experience when processing graphical data than the GTX 950M.

The GeForce GTX 950M 2GB requires 50 Watts to run and the GeForce GTX 670MX SLI requires 150 Watts. The GTX 670MX requires 100 Watts more than the GTX 950M to run. The difference is significant enough that the GTX 670MX may have an adverse affect on your yearly electricity bills in comparison to the GTX 950M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 950M 2GB is a Performance Mobile Graphics Card based on the first variant of the Maxwell architecture.

The first variant of the Maxwell Architecture succeeds the Kepler Architecture. Despite being also manufactured with a 28nm technology, it has an extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

It equips a GPU codenamed GM107-N16P-GT which has 5 SM activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The central unit runs at 914MHz and goes up to 993MHz, in Turbo Mode.

The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The memory clock operates at 1253MHz. The size of the frame buffer is adequate.

DirectX 12 Support (11.0 Hardware Default) and support for GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 50W, it may be equipped in average sized notebooks.

Because GeForce GTX 950M 2GB is just a higher clocked GeForce GTX 850M v2 2GB, its performance is only about 5% faster than its predecessors and so GeForce GTX 860M 2GB is still faster.
Still, it still offers decent gaming at 1920x1080 and most modern games should run fluently at high settings.

System Suggestions
We recommend a strong processor (Intel Core i5 Mobile) and 8GB of RAM for a notebook with GeForce GTX 950M 2GB.
GeForce 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.
