In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce4 Go 420 are very slightly better than the Nvidia GeForce 8200M G.

The GeForce 8200M G was released over three years more recently than the GeForce4 Go 420, and so the GeForce 8200M G is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce4 Go 420 when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce4 Go 420 has 32 MB video memory, but the GeForce 8200M G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce4 Go 420 has 2 Shader Processing Units and the GeForce 8200M G has 8. However, the actual shader performance of the GeForce4 Go 420 is 0 and the actual shader performance of the GeForce 8200M G is 3. The GeForce 8200M G having 3 better shader performance is not particularly notable, as altogether the GeForce4 Go 420 performs better when taking into account other relevant data.

GPU Mini Review

Mini ReviewGeForce4 Go 420 is an entry-middle-class GPU part of the GeForce4 Go Series released by in 2002.
It's based on the architecture "NV17M", same used on the desktop 'GeForce4 MX440' but slower due to the lower clock frequencies and the cheaper Memory Bus .
The performance is very limited, so today's games are unplayable.
GeForce 8400M GT is an on-board GPU part of the 8000M Series released by NVIDIA, in 2007.
Only less demanding games can be played smoothly.
