Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 750M are very slightly better than the Nvidia GeForce GT 740M.
The GeForce GT 750M has a 157 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GT 740M. This results in the GeForce GT 750M providing 5 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 GT 750M has a 157 MHz higher core clock speed than the GeForce GT 740M and the same number of Render Output Units. This results in the GeForce GT 750M providing 2.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
Both the GeForce GT 740M and the GeForce GT 750M were released at the same time, so are likely to be quite similar.
The GeForce GT 750M has 2048 MB more video memory than the GeForce GT 740M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 750M also has superior memory performance overall.
The GeForce GT 750M has 3.2 GB/sec greater memory bandwidth than the GeForce GT 740M, which means that the memory performance of the GeForce GT 750M is marginally better than the GeForce GT 740M.
Both the GeForce GT 740M and the GeForce GT 750M 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 GeForce GT 750M has 5 GTexel/s better Texture Fill Rate, 2.5 GPixel/s better Pixel Fill Rate, and 3.2 GB/sec greater memory bandwidth, so should have a marginally faster performance than the GeForce GT 740M.
The GeForce GT 740M requires 33 Watts to run and the GeForce GT 750M requires 50 Watts. The GeForce GT 750M requires 17 Watts more than the GeForce GT 740M to run. The difference is not significant enough for the GeForce GT 750M to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 740M.

|Mini Review||GeForce GT 740M is a middle-class mobile graphics card based on the 28nm, Kepler architecture. |
It's based on the Kepler GK107 Core and offers 384 Shader Processing Units, 32 TMUs and 16 ROPs, on a 128-bit memory interface of DDR3. The central unit runs at 810MHz (890MHz in Turbo Mode) and the memory clock operates at up to 900MHz.
Its performance is therefore similar (though slower) to the DDR3 Variant of previous GeForce GT 650M and so most modern games will run at medium or high settings. Its power consumption should be lower, thanks to the power optimizations.
This Graphics Card needs to be paired with an average Quad Core CPU and can only achieve fluent frame rates at 1366x768.
|GeForce GT 750M is a fast-middle-class GFX, based on the 2012, 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 967MHz and the memory clock operates at up to 1000MHz.
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.
