Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 755M are very slightly better than the Nvidia GeForce GT 750M.
The GeForce GT 755M has a 13 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GT 750M. This results in the GeForce GT 755M providing 0.5 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 755M has a 13 MHz higher core clock speed than the GeForce GT 750M and the same number of Render Output Units. This results in the GeForce GT 755M providing 0.2 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 GeForce GT 755M was released less than a year after the GeForce GT 750M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 750M has 2048 MB more video memory than the GeForce GT 755M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GT 755M has superior memory performance.
The GeForce GT 755M has 54.4 GB/sec greater memory bandwidth than the GeForce GT 750M, which means that the memory performance of the GeForce GT 755M is much better than the GeForce GT 750M.
Both the GeForce GT 755M 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 755M has 0.5 GTexel/s better Texture Fill Rate, 0.2 GPixel/s better Pixel Fill Rate, and 54.4 GB/sec greater memory bandwidth, so should have a noticeably faster performance than the GeForce GT 750M.
The GeForce GT 755M requires 50 Watts to run and the GeForce GT 750M requires 50 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

|Mini Review||GeForce GT 755M is a fast-middle-class Graphics Card 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 fast GDDR5. While the central unit runs at 980MHZ, the memory clock operates at 1350MHz.
Compared to GeForce GT 750M, it only comes with a GDDR5 variant that's higher clocked than the DDR3 variant of the previous in series, GeForce GT 750M.
Its performance is only slightly better than GeForce GT 750M and so still not suited for a 1080p resolution.
|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.
