Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 750M SLI are noticeably better than the Nvidia GeForce GTX 765M.
The GT 750M has a 170 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GTX 765M. This results in the GT 750M providing 10.9 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 GT 750M has a 170 MHz higher core clock speed and 16 more Render Output Units than the GeForce GTX 765M. This results in the GT 750M providing 18.1 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 GeForce GTX 765M was released less than a year after the GT 750M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GT 750M has 1024 MB more video memory than the GeForce GTX 765M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 750M also has superior memory performance overall.
The GT 750M has 95.9 GB/sec greater memory bandwidth than the GeForce GTX 765M, which means that the memory performance of the GT 750M is massively better than the GeForce GTX 765M.
Both the GeForce GTX 765M and the GeForce GT 750M SLI have 768 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, the GT 750M has 10.9 GTexel/s better Texture Fill Rate, 18.1 GPixel/s better Pixel Fill Rate, and 95.9 GB/sec greater memory bandwidth, so should have a significantly faster performance than the GeForce GTX 765M.
The GeForce GTX 765M requires 75 Watts to run and the GeForce GT 750M SLI requires 80 Watts. The GT 750M requires 5 Watts more than the GeForce GTX 765M to run. The difference is not significant enough for the GT 750M to have a noticeably larger impact on your yearly electricity bills than the GeForce GTX 765M.

|Mini Review||GeForce GTX 770M is a high-end mobile graphics card based on the 28nm, Kepler architecture. |
It's based on the Kepler GK106 Core and offers an identical core configuration to the desktop, GeForce GTX 650 Ti. Therefore, it offers 768 Shader Processing Units, 64 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5.
While the central unit runs at 850MHz and goes up to XXXMHz, in Turbo Mode, the memory clock operates at 1000MHz. Its power consumption is around 75W and thus only suited for average to large notebooks.
Its at heart just a higher-clocked GeForce GTX 760M.
Paired with a strong Quad Core, all demanding games will run at the highest settings, using a 1680x1050 resolution.
|GeForce GT 750M SLI is a solution of two GeForce GT 750M put together using NVIDIA'S SLI technology. |
SLI relies a lot on proper driver support and may cause micro stuttering in FPS below 30. This means this combination might even perform worse than a single GT 750M.
The optimal performance it delivers is better than single GeForce GTX 675M and on the range of a GeForce GTX 675MX.
Therefore, this combination is sufficient for gaming at 1080p and most demanding games can be played at the highest settings.
