In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 485M SLI are massively better than the AMD Radeon HD 8850M.

The Radeon HD 8850M has a 50 MHz higher core clock speed than the GTX 485M, but the GTX 485M has 88 more Texture Mapping Units than the Radeon HD 8850M. As a result, the GTX 485M exhibits a 48.6 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 50 MHz higher core clock speed than the GTX 485M, but the GTX 485M has 48 more Render Output Units than the Radeon HD 8850M. As a result, the GTX 485M exhibits a 26.8 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 a year more recently than the GTX 485M, and so the Radeon HD 8850M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 485M.

The GTX 485M 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 GTX 485M also has superior memory performance overall.

The GTX 485M has 160 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GTX 485M is massively better than the Radeon HD 8850M.

The Radeon HD 8850M has 640 Shader Processing Units and the GeForce GTX 485M SLI has 768. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the GTX 485M is 883. The GTX 485M having 387 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 485M delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 8850M.

The Radeon HD 8850M transistor size technology is 12 nm (nanometers) smaller than the GTX 485M. This means that the Radeon HD 8850M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 485M.

The Radeon HD 8850M requires 45 Watts to run and the GeForce GTX 485M SLI requires 200 Watts. The GTX 485M requires 155 Watts more than the Radeon HD 8850M to run. The difference is significant enough that the GTX 485M 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.

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.
GeForce GTX 485M SLI is a solution of two GeForce GTX 485M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 485M 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 485M 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 485M.
Even the most demanding games will run at the highest settings.
