In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800M GT SLI are massively better than the Nvidia GeForce G 205M.

The GeForce G 205M was released over a year more recently than the 9800M GT, and so the GeForce G 205M 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 9800M GT has 1024 MB video memory, but the GeForce G 205M does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce G 205M has 16 Shader Processing Units and the GeForce 9800M GT SLI has 192. However, the actual shader performance of the GeForce G 205M is 18 and the actual shader performance of the 9800M GT is 96. The 9800M GT having 78 better shader performance and an altogether better performance when taking into account other relevant data means that the 9800M GT delivers a massively smoother and more efficient experience when processing graphical data than the GeForce G 205M.

The 9800M GT transistor size technology is 25 nm (nanometers) smaller than the GeForce G 205M. This means that the 9800M GT is expected to run slightly cooler and achieve higher clock frequencies than the GeForce G 205M.

The GeForce G 205M requires 12 Watts to run and the GeForce 9800M GT SLI requires 130 Watts. The 9800M GT requires 118 Watts more than the GeForce G 205M 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 GeForce G 205M.

GPU Mini Review

Mini ReviewGeForce G 205M is an integrated GPU with no dedicated memory.
It's based on the G96 Core and therefore offers 16 Shader Processing Units, 8 TMUs and 4 ROPs on either DDR2 or DDR3, depending on the laptop's system RAM. Commonly, it was seen paired with DDR2 on a 64-bit bus width (due to laptop's system RAM not being dual channelled).
It's at heart a renamed GeForce 9400M GS. This GPU was discontinued due to its very limited performance - which was horrible, even compared to G 210M.
GeForce 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.
