In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850M are very slightly better than the AMD Radeon HD 8850M.

The Radeon HD 7850M has a 50 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon HD 8850M. This results in the Radeon HD 7850M providing 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 7850M has a 50 MHz higher core clock speed than the Radeon HD 8850M and the same number of Render Output Units. This results in the Radeon HD 7850M providing 0.8 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 Radeon HD 7850M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 8850M and the Radeon HD 7850M 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 7850M has 32 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the Radeon HD 7850M is noticeably better than the Radeon HD 8850M.

Both the Radeon HD 8850M and the Radeon HD 7850M have 640 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the Radeon HD 8850M is 496 and by the Radeon HD 7850M is 367. Knowing that the shader performance of the Radeon HD 8850M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon HD 8850M requires 45 Watts to run and the Radeon HD 7850M requires 40 Watts. The Radeon HD 8850M requires 5 Watts more than the Radeon HD 7850M to run. The difference is not significant enough for the Radeon HD 8850M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7850M.

GPU Mini Review

Mini ReviewOverview
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.
Overview
Radeon HD 7850M is a Performance Mobile Graphics Card based on the First revision of the GCN Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU codenamed Heathrow Pro which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit Operates at 675MHz.

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 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 40W, it is suited for 17" or larger laptops.

Performance
Gaming benchmarks put its on average with 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 7850M.
