In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 750M 2GB GDDR5 are noticeably better than the AMD Radeon HD 8850M.

The GT 750M has a 316 MHz higher core clock speed but 8 fewer Texture Mapping Units than the Radeon HD 8850M. The lower TMU count doesn't matter, though, as altogether the GT 750M manages to provide 5.1 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 316 MHz higher core clock speed than the Radeon HD 8850M and the same number of Render Output Units. This results in the GT 750M providing 5.1 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 Radeon HD 8850M was released less than a year after the GT 750M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 750M 2GB GDDR5 and the Radeon HD 8850M 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 32 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GT 750M is noticeably better than the Radeon HD 8850M.

The GeForce GT 750M 2GB GDDR5 has 384 Shader Processing Units and the Radeon HD 8850M has 640. However, the actual shader performance of the GT 750M is 406 and the actual shader performance of the Radeon HD 8850M is 422. The Radeon HD 8850M having 16 better shader performance is not particularly notable, as altogether the GT 750M performs better when taking into account other relevant data.

The GeForce GT 750M 2GB GDDR5 requires 50 Watts to run and the Radeon HD 8850M requires 45 Watts. The GT 750M requires 5 Watts more than the Radeon HD 8850M to run. The difference is not significant enough for the GT 750M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 8850M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 750M v4 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-N14P-GT which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is initially clocked at 941MHz and goes up to 1058MHz, in Turbo Mode.

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 1000MHz.

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 750M v2 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 750M v4.
Overview
Radeon HD 8850M is a Performance Mobile Graphics Card based on the Second Revision of the GCN Architecture.

Architecture
The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.

GPU
It equips a GPU codenamed Venus PRO which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit Initially Operates at 625MHz and goes up to 775MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 1000MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 45W, it is suited for 17" or larger laptops.

Performance
Gaming benchmarks put its performance somewhat above NVIDIA's GeForce GT 750M.

System Suggestions
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8850M.
