In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 965M 4GB SLI are significantly better than the Nvidia GeForce GTX 675M SLI.

The GTX 965M has a 304 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 675M. This results in the GTX 965M providing 38.9 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 965M has a 304 MHz higher core clock speed than the GTX 675M and the same number of Render Output Units. This results in the GTX 965M providing 19.4 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 965M was released over a year more recently than the GTX 675M, and so the GTX 965M 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 965M 4GB 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 32 GB/sec greater memory bandwidth than the GTX 965M, which means that the memory performance of the GTX 675M is noticeably better than the GTX 965M.

The GeForce GTX 965M 4GB SLI has 2048 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GTX 965M is 2627 and the actual shader performance of the GTX 675M is 952. The GTX 965M having 1675 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 965M delivers a significantly smoother and more efficient experience when processing graphical data than the GTX 675M.

The GTX 965M transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 965M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 965M 4GB SLI requires 100 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 100 Watts more than the GTX 965M 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 965M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 965M 4GB SLI is a solution of two GeForce GTX 965M 4GB put together using NVIDIA's SLI technology.

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.

GPU
It consists of 2 GPUs Codenamed GM204-N16E-GS which, together, offer 2048 Shader Processing Units, 128 TMUs and 64 ROPs. The central unit runs at 924MHz and goes up to 950MHz, in Turbo Mode.

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

Power Consumption
Power Consumption is around 100W.

Performance
Gaming benchmarks prove that at 2560x1440, the best suited resolution, GeForce GTX 965M 4GB SLI is around 10% faster than a Single GeForce GTX 980M.

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.
