In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 285M SLI are noticeably better than the AMD Radeon HD 8850M.

The Radeon HD 8850M has a 25 MHz higher core clock speed than the GTX 285M, but the GTX 285M has 88 more Texture Mapping Units than the Radeon HD 8850M. As a result, the GTX 285M exhibits a 51.8 GTexel/s better Texture Fill Rate than the Radeon HD 8850M. 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 8850M has a 25 MHz higher core clock speed than the GTX 285M, but the GTX 285M has 16 more Render Output Units than the Radeon HD 8850M. As a result, the GTX 285M exhibits a 9.2 GPixel/s better Pixel Fill Rate than the Radeon HD 8850M. 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 over three years more recently than the GTX 285M, and so the Radeon HD 8850M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 285M when running the latest games.

The Radeon HD 8850M and the GeForce GTX 285M SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 285M has 33.3 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GTX 285M is noticeably better than the Radeon HD 8850M.

The Radeon HD 8850M has 640 Shader Processing Units and the GeForce GTX 285M SLI has 256. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the GTX 285M is 154. The Radeon HD 8850M having 342 better shader performance is not particularly notable, as altogether the GTX 285M performs better when taking into account other relevant data.

The Radeon HD 8850M transistor size technology is 27 nm (nanometers) smaller than the GTX 285M. This means that the Radeon HD 8850M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 285M.

The Radeon HD 8850M requires 45 Watts to run and the GeForce GTX 285M SLI requires 150 Watts. The GTX 285M requires 105 Watts more than the Radeon HD 8850M to run. The difference is significant enough that the GTX 285M 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.
GeForce GTX 285M SLI is a solution of two GeForce GTX 285M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 285M to know more about its chip.
As usual, SLI 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, up to X% better than a single GeForce GTX 285M performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 285M.
Most demanding games will run at the highest settings with fluent frame rates (30+).
