In terms of overall gaming performance, the graphical capabilities of the Intel GMA 3000 are massively better than the Nvidia GeForce 6150 LE.

The GMA 3000 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GMA 3000 was released over a year more recently than the GeForce 6150 LE, and so the GMA 3000 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6150 LE.

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 GeForce 6150 LE and the GMA 3000 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GMA 3000 has 6.4 GB/sec greater memory bandwidth than the GeForce 6150 LE, which means that the memory performance of the GMA 3000 is marginally better than the GeForce 6150 LE.

The GeForce 6150 LE has 2 Shader Processing Units and the GMA 3000 has 8. However, the actual shader performance of the GeForce 6150 LE is 1 and the actual shader performance of the GMA 3000 is 0. The GeForce 6150 LE having 1 better shader performance is not particularly notable, as altogether the GMA 3000 performs better when taking into account other relevant data.
