In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8790M are significantly better than the Nvidia GeForce 920M 2GB.

The Radeon HD 8790M has a 275 MHz higher core clock speed but 8 fewer Texture Mapping Units than the GeForce 920M 2GB. The lower TMU count doesn't matter, though, as altogether the Radeon HD 8790M manages to provide 2 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 Radeon HD 8790M has a 275 MHz higher core clock speed than the GeForce 920M 2GB and the same number of Render Output Units. This results in the Radeon HD 8790M providing 2.2 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 920M 2GB was released over a year more recently than the Radeon HD 8790M, and so the GeForce 920M 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 8790M.

The GeForce 920M 2GB and the Radeon HD 8790M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon HD 8790M has 49.6 GB/sec greater memory bandwidth than the GeForce 920M 2GB, which means that the memory performance of the Radeon HD 8790M is noticeably better than the GeForce 920M 2GB.

Both the GeForce 920M 2GB and the Radeon HD 8790M have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 920M 2GB is 366 and by the Radeon HD 8790M is 294. Knowing that the shader performance of the GeForce 920M 2GB is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce 920M 2GB requires 25 Watts to run and the Radeon HD 8790M requires 35 Watts. The Radeon HD 8790M requires 10 Watts more than the GeForce 920M 2GB to run. The difference is not significant enough for the Radeon HD 8790M to have a noticeably larger impact on your yearly electricity bills than the GeForce 920M 2GB.

GPU Mini Review

Mini ReviewOverview
GeForce 920M 2GB is an Entry-Level Mobile Graphics Card based on the second revision of the Kepler Architecture.

Architecture
This Graphics Card Equips the Kepler GK208 GPU which is essentially a power optimized version of the GK107 GPU. Whereas it still has a count of 2 Stream Multiprocessors, the bus-width has been cut in half to allow for even a smaller power consumption and consequently a cooler operating temperature.
Additionally, the GK208 GPU allows the Central Unit to reach a significant higher frequency, thanks to the Kepler Boost 2.0 Technology. The better the laptop's cooling system, the higher the frequency.

GPU
It equips a GPU Codenamed GK208-N16V-GM which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is Initially clocked at 575MHz and goes up to 954MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

Power Consumption
With a rated board TDP of 25W, it is suited for small laptops.

Performance
GeForce 920M 2GB is essentially a slightly faster GeForce GT 735M and offers more or less comparable performance.

System Suggestions
We recommend a Modest Processor and 4GB of RAM for a system with GeForce GT 920M 2GB.
Overview
Radeon HD 8790M is a Fast-Middle-Class 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 Mars XTX which has 6 Compute Units activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit Initially Operates at 850MHz and goes up to 900MHz, 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 adequate. 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 35W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its performance slightly below NVIDIA's GeForce GTX 660M.

System Suggestions
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8790M.
