Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 650M are significantly better than the Nvidia GeForce GT 720M.
The GeForce GT 720M has a 38 MHz higher core clock speed than the GeForce GT 650M, but the GeForce GT 650M has 16 more Texture Mapping Units than the GeForce GT 720M. As a result, the GeForce GT 650M exhibits a 13.8 GTexel/s better Texture Fill Rate than the GeForce GT 720M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GT 720M has a 38 MHz higher core clock speed than the GeForce GT 650M, but the GeForce GT 650M has 8 more Render Output Units than the GeForce GT 720M. As a result, the GeForce GT 650M exhibits a 6.9 GPixel/s better Pixel Fill Rate than the GeForce GT 720M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GT 720M was released over a year more recently than the GeForce GT 650M, and so the GeForce GT 720M is likely to have better driver support, meaning it will be more optimized for running the latest games.
The GeForce GT 650M has 1024 MB more video memory than the GeForce GT 720M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 650M also has superior memory performance overall.
The GeForce GT 650M has 14.4 GB/sec greater memory bandwidth than the GeForce GT 720M, which means that the memory performance of the GeForce GT 650M is slightly better than the GeForce GT 720M.
The GeForce GT 720M has 96 Shader Processing Units and the GeForce GT 650M has 384. However, the actual shader performance of the GeForce GT 720M is 180 and the actual shader performance of the GeForce GT 650M is 397. The GeForce GT 650M having 217 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 650M delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GT 720M.
The GeForce GT 650M requires 45 Watts to run but there is no entry for the GeForce GT 720M.

|Mini Review||GeForce GT 720M is an entry-level GFX still based on the Fermi architecture. |
It's based on the Fermi GF117 Core, which is manufactured with a 28nm technology, does comes optimized for lower power consumption and is expect to produce less heat and offers 96 Shader Processing Units, 16 TMUs and 8 ROPs, on a 64-bit memory interface of DDR3. The central unit runs at 938MHz and the memory clock operates at 900MHz.
Its performance lies, therefore, somewhere between GeForce GT 625M and GeForce GT 630M. In smaller resolutions, it should perform considerably better but the 64-bit bus width will become a bottleneck for superior resolutions (720p+).
|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 DDR3 version and so the central unit runs at up to 900MHz and the memory clock operates at 900MHz.
However, ultimately, laptop manufacturer's may change these values to their liking.
The DDR3 variant will perform considerably better than the GDDR5 version, on lower resolutions and is better suited for smaller notebooks.
