Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 750M 2GB GDDR5 are marginally better than the Nvidia GeForce GT 650M GDDR5.

The GT 750M has a 196 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 650M. This results in the GT 750M providing 6.3 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 196 MHz higher core clock speed than the GT 650M and the same number of Render Output Units. This results in the GT 750M providing 3.2 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 GT 750M was released over a year more recently than the GT 650M, and so the GT 750M is likely to have better driver support, meaning it will be more optimized for running the latest games.

The GeForce GT 750M 2GB GDDR5 and the GeForce GT 650M GDDR5 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GT 750M has 16 GB/sec greater memory bandwidth than the GT 650M, which means that the memory performance of the GT 750M is slightly better than the GT 650M.

Both the GeForce GT 750M 2GB GDDR5 and the GeForce GT 650M GDDR5 have 384 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the GT 750M has 6.3 GTexel/s better Texture Fill Rate, 3.2 GPixel/s better Pixel Fill Rate, and 16 GB/sec greater memory bandwidth, so should have a slightly faster performance than the GT 650M.

The GeForce GT 750M 2GB GDDR5 requires 33 Watts to run and the GeForce GT 650M GDDR5 requires 45 Watts. The GT 650M requires 12 Watts more than the GT 750M 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 GT 750M.

GPU Mini Review

Mini ReviewGeForce GT 750M 2GB GDDR5 is a fast-middle-class GFX, based on the 28nm, 2012 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 941Hz(XXXMHz in Turbo Mode) and the memory clock operates at up to 1250MHz.
However, ultimately, laptop manufacturer's may change these values to their liking.
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.
