In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675M SLI are very slightly better than the Nvidia GeForce GTX 765M SLI.

The GTX 765M has a 177 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 675M. This results in the GTX 765M providing 22.6 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 765M has a 177 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 32 more Render Output Units than the GTX 765M. As a result, the GTX 675M exhibits a 14.2 GPixel/s better Pixel Fill Rate than the GTX 765M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 765M was released over a year more recently than the GTX 675M, and so the GTX 765M 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 765M 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 64 GB/sec greater memory bandwidth than the GTX 765M, which means that the memory performance of the GTX 675M is much better than the GTX 765M.

The GeForce GTX 765M SLI has 1536 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GTX 765M is 1326 and the actual shader performance of the GTX 675M is 952. The GTX 765M having 374 better shader performance is not particularly notable, as altogether the GTX 675M performs better when taking into account other relevant data.

The GTX 765M transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GTX 765M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce GTX 765M SLI requires 125 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 75 Watts more than the GTX 765M 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 765M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 765M SLI is a solution of two GeForce GTX 765M put together using NVIDIA's SLI technology.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It consists of 2 GPUs Codenamed GK106-N14E-GE-B-A1 which, together, offer 1536 Shader Processing Units, 128 TMUs and 32 ROPs. The central unit runs at 797MHz and goes up to 863MHz, 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 1000MHz.

Power Consumption
Power Consumption lies between 100W and 150W.

Performance
Because SLI Relies on Proper Driver Support for Scaling, Performance may vary from game to game.
Overall, GeForce GTX 765M SLI should offer Performance Comparable to a single GeForce GTX 780M at 1920x1080.

System Suggestions
GeForce GTX 765M SLI is best suited for resolutions up to and including 1920x1080.
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.
