In terms of overall gaming performance, the graphical capabilities of the AMD Mobility Radeon HD 4870 x2 are very slightly better than the Nvidia GeForce 9800M GT SLI.

The Radeon HD was released less than a year after the 9800M GT, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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

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

The GeForce 9800M GT SLI has 192 Shader Processing Units and the Mobility Radeon HD 4870 x2 has 1600. However, the actual shader performance of the 9800M GT is 96 and the actual shader performance of the Radeon HD is 572. The Radeon HD having 476 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD delivers a significantly smoother and more efficient experience when processing graphical data than the 9800M GT.

The Radeon HD transistor size technology is 10 nm (nanometers) smaller than the 9800M GT. This means that the Radeon HD is expected to run very slightly cooler and achieve higher clock frequencies than the 9800M GT. While they exhibit similar graphical performance, the Radeon HD should consume less power than the 9800M GT.

The GeForce 9800M GT SLI requires 130 Watts to run and the Mobility Radeon HD 4870 x2 requires 130 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

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.
