In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 970M 6GB are noticeably better than the Nvidia GeForce GTX 675M SLI.

The GTX 970M has a 304 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 48 more Texture Mapping Units than the GTX 970M. As a result, the GTX 675M exhibits a 5.5 GTexel/s better Texture Fill Rate than the GTX 970M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 970M has a 304 MHz higher core clock speed but 16 fewer Render Output Units than the GTX 675M. The lower ROP count doesn't matter, though, as altogether the GTX 970M manages to provide 4.7 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 970M was released over a year more recently than the GTX 675M, and so the GTX 970M 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 GTX 970M 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, the overall memory performance is about the same.

The GTX 675M has 71.7 GB/sec greater memory bandwidth than the GTX 970M, which means that the memory performance of the GTX 675M is much better than the GTX 970M.

The GeForce GTX 970M 6GB has 1280 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GTX 970M is 1716 and the actual shader performance of the GTX 675M is 952. The GTX 970M having 764 better shader performance is not particularly notable, as altogether the GTX 675M performs better when taking into account other relevant data.

The GTX 970M transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 970M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 970M 6GB requires 81 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 119 Watts more than the GTX 970M 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 970M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 970M 6GB is a high-end Mobile Graphics Card based on the second revision of the Maxwell architecture.

Architecture
The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression 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.
The Second Revision of Maxwell also adds the VXGI (Voxel Global Illumination) Technology which makes scenes significantly more lifelike and believable as light interacts more realistically in the game environment and the MFAA Technology which provides the same effect as MSAA but at a much lower performance cost.

GPU
It equips a GPU codenamed GM204 which has 10 SM activated and thus offers 1280 Shader Processing Units, 80 TMUs and 48 ROPs. The central unit runs at 924MHz and goes up to 993MHz, in Turbo Mode.

Memory
The GPU accesses a 6GB frame buffer of fast GDDR5, through a 192-bit memory interface. The memory clock operates at 1253MHz. The size of the frame buffer is exaggerated and in no way adds extra performance.

Features
DirectX 12.0 Support (11.0 Hardware Default) and support for SLI, GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Temperature
The Card is known to run cool. However, ultimately, it all depends on the notebook's cooling system.

Power Consumption
With a rated board TDP of 81W, it will only be equipped in large notebooks.

Performance
Benchmarks indicate its performance is over 10% faster than GeForce GTX 880M. Therefore, it should even surpass GeForce GTX 760 and be around as fast as desktop GeForce GTX 670.
GeForce GTX 970M is therefore the second fastest mobile Graphics Card as of October 2014 and AMD's Radeon R9 M290X is beaten in over 20%.

System Suggestions
We recommend a very strong processor (Intel Core i7 Mobile Quad Core) and 8GB of RAM for a notebook with GeForce GTX 970M 6GB.
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.
