In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800M GTX SLI are very slightly better than the AMD Radeon HD 6850M.

The Radeon HD 6850M was released over a year more recently than the 9800M GTX, and so the Radeon HD 6850M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 9800M GTX.

The 9800M GTX has 1024 MB more video memory than the Radeon HD 6850M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the 9800M GTX also has superior memory performance overall.

The 9800M GTX has 76.8 GB/sec greater memory bandwidth than the Radeon HD 6850M, which means that the memory performance of the 9800M GTX is much better than the Radeon HD 6850M.

The GeForce 9800M GTX SLI has 224 Shader Processing Units and the Radeon HD 6850M has 800. However, the actual shader performance of the 9800M GTX is 112 and the actual shader performance of the Radeon HD 6850M is 270. The Radeon HD 6850M having 158 better shader performance is not particularly notable, as altogether the 9800M GTX performs better when taking into account other relevant data.

The Radeon HD 6850M transistor size technology is 25 nm (nanometers) smaller than the 9800M GTX. This means that the Radeon HD 6850M is expected to run slightly cooler and achieve higher clock frequencies than the 9800M GTX. While they exhibit similar graphical performance, the Radeon HD 6850M should consume less power than the 9800M GTX.

The GeForce 9800M GTX SLI requires 150 Watts to run and the Radeon HD 6850M requires 50 Watts. The 9800M GTX requires 100 Watts more than the Radeon HD 6850M to run. The difference is significant enough that the 9800M GTX may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 6850M.

GPU Mini Review

Mini ReviewGeForce 9800M GTX SLI is a solution of two GeForce 9800M GTX put together using NVIDIA'S SLI technology.
Check the page of GeForce 9800M GTX 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 9800M GTX 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 9800M GTX.
A few demanding games will run at the highest settings with fluent frame rates (30+) but overall most games will require reduced settings to be played optimally.
Radeon HD 6850M is a high-end GPU based on the 40nm Terrascale 2 architecture.
It's based on the Juniper Core (therefore related to Radeon HD 6770) and offers 800 Shader Processing Units, 40 TMUs and 16 ROPs on a 128-bit memory interface. Though fast GDDR5 is supported, the most common version features standard DDR3 but comes higher clocked. Its central clock runs at 675MHz and the memory clock operates at 800MHz.
Compared to Radeon HD 6850M, its performance is considerably slower due to being paired with standard DDR3 and the power consumption should remain similar since GDDR5 is more energy efficient.
Using a 720p resolution, most of today's games are only playable at medium settings but with very fluent frame rates (45+).
