Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 765M are marginally better than the Nvidia GeForce GT 650M SLI.
The GeForce GTX 765M has a 7 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 650M. This results in the GeForce GTX 765M providing 0.4 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 GeForce GTX 765M has a 7 MHz higher core clock speed than the GT 650M, but the GT 650M has 16 more Render Output Units than the GeForce GTX 765M. As a result, the GT 650M exhibits a 12.5 GPixel/s better Pixel Fill Rate than the GeForce GTX 765M. 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 over a year more recently than the GT 650M, and so the GeForce GTX 765M is likely to have better driver support, meaning it will be more optimized for running the latest games.
The GT 650M 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 650M also has superior memory performance overall.
The GT 650M has 63.9 GB/sec greater memory bandwidth than the GeForce GTX 765M, which means that the memory performance of the GT 650M is much better than the GeForce GTX 765M.
Both the GeForce GTX 765M and the GeForce GT 650M SLI have 768 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the . Knowing that the shader performance of the GeForce GTX 765M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.
The GeForce GTX 765M requires 75 Watts to run and the GeForce GT 650M SLI requires 90 Watts. The GT 650M requires 15 Watts more than the GeForce GTX 765M to run. The difference is not significant enough for the GT 650M 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 650M SLI is a solution of two GeForce GT 650M GDDR5 put together using NVIDIA'S SLI technology. |
Check the page of GeForce GT 650M GDDR5 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 on level with a single GeForce GTX 670MX. However, its performance may be the same or worse as a single GT 650M, depending on whether or not the 3D game supports SLI.
Even so, most demanding games will run at the highest settings.
It's worth mentioning SLIed GT 650M are only made with GDDR5 variants of GT 650M.
