In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800M GT SLI are massively better than the Nvidia Geforce 405M.

The Geforce 405M was released over three years more recently than the 9800M GT, and so the Geforce 405M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 9800M GT when running the latest games.

The 9800M GT has 512 MB more video memory than the Geforce 405M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the 9800M GT also has superior memory performance overall.

The 9800M GT has 89.6 GB/sec greater memory bandwidth than the Geforce 405M, which means that the memory performance of the 9800M GT is much better than the Geforce 405M.

The GeForce 9800M GT SLI has 192 Shader Processing Units and the Geforce 405M has 16. However, the actual shader performance of the 9800M GT is 96 and the actual shader performance of the Geforce 405M is 22. The 9800M GT having 74 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 405M.

The Geforce 405M transistor size technology is 25 nm (nanometers) smaller than the 9800M GT. This means that the Geforce 405M 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 Geforce 405M requires 14 Watts. The 9800M GT requires 116 Watts more than the Geforce 405M 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 405M.

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.
GeForce 405M is the latest addition to the 400M Series released by NVIDIA in 2010-2012.
It's a renamed GeForce 315M, based on the GT218 architecture.
It only supports up to 512MB DDR3/GDDR3 memory type and DirectX 10.1. GeForce 405M is one of the weakest integrated GPUs with dedicated memory currently in the market, it has only 16 Pipelines and so, along with other factors, the performance is very limited.
Therefore, the most demanding games are probably unplayable even at the lowest settings while demanding games should run fluently at low settings. Less demanding games will run fluently from medium to high settings, depending on the amount of video memory required, since GeForce 405M only has up to 512MB.
