Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 765M are significantly better than the Nvidia GeForce GT 650M GDDR5.
The GeForce GTX 765M has a 52 MHz higher core clock speed and 32 more Texture Mapping Units than the GT 650M. This results in the GeForce GTX 765M providing 27.2 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 52 MHz higher core clock speed than the GT 650M and the same number of Render Output Units. This results in the GeForce GTX 765M providing 0.9 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 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 GeForce GTX 765M has 1024 MB more video memory than the GT 650M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 765M also has superior memory performance overall.
The GeForce GTX 765M has 0.1 GB/sec greater memory bandwidth than the GT 650M, which means that the memory performance of the GeForce GTX 765M is marginally better than the GT 650M.
The GeForce GTX 765M has 768 Shader Processing Units and the GeForce GT 650M GDDR5 has 384. The GeForce GTX 765M having 384 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 765M delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 650M.
The GeForce GTX 765M requires 75 Watts to run and the GeForce GT 650M GDDR5 requires 45 Watts. The GeForce GTX 765M requires 30 Watts more than the GT 650M to run. The difference is not significant enough for the GeForce GTX 765M to have a noticeably larger impact on your yearly electricity bills than the GT 650M.

|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 is a fast-middle-class laptop graphics card based on the 28nm, Kepler architecture. |
It's Based on the Kepler GK107 Core and therefore offers 384 Shader Processing Units, 32 TMUs and 16 ROPs, on a 128-bit memory interface of either fast GDDR5 or standard DDR3. The central unit's and operating memory clock's speed depend on the memory variant.
This is the GDDR5 version and so the central unit runs at 745MHz (835MHz in Turbo Mode) and the memory clock operates at 1000MHz.
The GDDR5 version gains the upper-hand on higher resolutions (1600x900, 1980x800) and has more tolerance for image improving techniques, such as MSAA and thus is better suited for larger notebooks.
