Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 755M are noticeably 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 755M and the GeForce GT 750M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GT 755M has 57.6 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. While the two GPUs have the same number of SPUs, the actual performance delivered by the . Knowing that the shader performance of the GeForce GT 750M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

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.

GPU Mini Review

Mini ReviewOverview
GeForce GT 755M is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK107-GT-755M which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 980MHz.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 1350MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Kepler Boost, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 50W, it is suited for average sized laptops.

Performance
GeForce GT 755M is essentially a fast GeForce GTX 660M.
Gaming benchmarks indicate its performance is only slightly below the desktop GeForce GTX 650.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 755M.
