In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8970M Crossfire are massively better than the AMD Radeon HD 8850M.

The HD 8970M has a 225 MHz higher core clock speed and 120 more Texture Mapping Units than the Radeon HD 8850M. This results in the HD 8970M providing 111 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 HD 8970M has a 225 MHz higher core clock speed and 48 more Render Output Units than the Radeon HD 8850M. This results in the HD 8970M providing 44.4 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 HD 8970M was released less than a year after the Radeon HD 8850M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 8970M has 2048 MB more video memory than the Radeon HD 8850M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 8970M also has superior memory performance overall.

The HD 8970M has 275.2 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the HD 8970M is massively better than the Radeon HD 8850M.

The Radeon HD 8850M has 640 Shader Processing Units and the Radeon HD 8970M Crossfire has 2560. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the HD 8970M is 1958. The HD 8970M having 1462 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8970M delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 8850M.

The Radeon HD 8850M requires 45 Watts to run and the Radeon HD 8970M Crossfire requires 200 Watts. The HD 8970M requires 155 Watts more than the Radeon HD 8850M to run. The difference is significant enough that the HD 8970M may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 8850M.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8850M is a Performance Mobile Graphics Card based on the Second Revision of the GCN 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.

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.

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.

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.

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.
Radeon HD 8970M Crossfire is a solution of two Radeon HD 8970M put together using AMD'S Crossfire technology.
Check the page of Radeon HD 8970M to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to twice as better as a single Radeon HD 8970M performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon HD 8970M.
Even the most demanding games will run at the highest settings.
