In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 850M 2GB are significantly better than the Nvidia GeForce GT 755M.

The GeForce GT 755M has a 44 MHz higher core clock speed than the GTX 850M, but the GTX 850M has 8 more Texture Mapping Units than the GeForce GT 755M. As a result, the GTX 850M exhibits a 6 GTexel/s better Texture Fill Rate than the GeForce GT 755M. 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 44 MHz higher core clock speed than the GTX 850M and the same number of Render Output Units. This results in the GeForce GT 755M providing 0.7 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 GTX 850M was released less than a year after the GeForce GT 755M, 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 GTX 850M 2GB 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 54.4 GB/sec greater memory bandwidth than the GTX 850M, which means that the memory performance of the GeForce GT 755M is much better than the GTX 850M.

The GeForce GT 755M has 384 Shader Processing Units and the GeForce GTX 850M 2GB has 640. However, the actual shader performance of the GeForce GT 755M is 376 and the actual shader performance of the GTX 850M is 937. The GTX 850M having 561 better shader performance is not particularly notable, as altogether the GeForce GT 755M performs better when taking into account other relevant data.

The GeForce GT 755M requires 50 Watts to run and the GeForce GTX 850M 2GB requires 45 Watts. The GeForce GT 755M requires 5 Watts more than the GTX 850M to run. The difference is not significant enough for the GeForce GT 755M to have a noticeably larger impact on your yearly electricity bills than the GTX 850M.

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.
PLEASE NOTE THAT THIS GRAPHICS CARD HAS 2 VARIANTS: DDR3 AND GDDR5. THIS IS THE DDR3 VARIANT.

GeForce GTX 850M 2GB is a fast-middle-class mobile graphics card. It is based on 28nm GM107 Core of the Maxwell architecture.

The Maxwell architecture features many improvements and amongst them is the extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.
GeForce GTX 850M 2GB DDR3 comes with a full variant of the GM107 Core and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit of standard DDR3. While the central unit runs at 936MHz and goes up to 1084MHz, in Turbo Mode, the memory clock operates at 1000MHz. It has a rated TDP board of around 45W.
The DDR3 variant is better suited for 720p but it comes higher clocked. Thus it proves to be way faster than GeForce GTX 750M and surpasses slightly the higher positioned GeForce GTX 760M. In fact, it should be pretty close to the desktop GeForce GTX 750.
This card should be paired with a Very Strong Dual Core Processor or a Decent Quad Core and at least 8GB of RAM.
