In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6950M are significantly better than the Nvidia GeForce 9800M GT SLI.

The Radeon HD 6950M was released over a year more recently than the 9800M GT, and so the Radeon HD 6950M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 9800M GT.

The GeForce 9800M GT SLI and the Radeon HD 6950M 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 6950M has 12.8 GB/sec greater memory bandwidth than the 9800M GT, which means that the memory performance of the Radeon HD 6950M is slightly better than the 9800M GT.

The GeForce 9800M GT SLI has 192 Shader Processing Units and the Radeon HD 6950M has 960. However, the actual shader performance of the 9800M GT is 96 and the actual shader performance of the Radeon HD 6950M is 278. The Radeon HD 6950M having 182 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 6950M delivers a noticeably smoother and more efficient experience when processing graphical data than the 9800M GT.

The Radeon HD 6950M transistor size technology is 25 nm (nanometers) smaller than the 9800M GT. This means that the Radeon HD 6950M is expected to run slightly cooler and achieve higher clock frequencies than the 9800M GT.

The GeForce 9800M GT SLI requires 130 Watts to run and the Radeon HD 6950M requires 50 Watts. The 9800M GT requires 80 Watts more than the Radeon HD 6950M to run. The difference is significant enough that the 9800M GT may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 6950M.

GPU Mini Review

Mini ReviewGeForce 9800M GT SLI is a solution of two GeForce 9800M GT put together using NVIDIA'S SLI technology.
Check the page of GeForce 9800M GT 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 GT 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 GT.
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 6950M is a high-end GPU based on the 40nm Terrascale 2 architecture.
It's based on the Barts Core (therefore related to Radeon HD 6850) and offers 980 Shader Processing Units, 48 TMUs and 32 ROPs on a 256-bit memory interface of fast GDDR5. Its central clock runs at 580MHz and the memory clock operates at 900MHz.
Its performance is not exceptionally good due to being heavily underclocked.
Most of today's modern games are playable at the highest settings but some exceptions will require lower resolutions or modest presets to be played optimally.
