In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 445M v2 are massively better than the Nvidia GeForce G 102M.

The GT 445M was released over a year more recently than the GeForce G 102M, and so the GT 445M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce G 102M.

The GT 445M has 512 MB more video memory than the GeForce G 102M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 445M also has superior memory performance overall.

The GT 445M has 33.6 GB/sec greater memory bandwidth than the GeForce G 102M, which means that the memory performance of the GT 445M is noticeably better than the GeForce G 102M.

The GeForce GT 445M v2 has 144 Shader Processing Units and the GeForce G 102M has 16. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the GeForce G 102M is 18. The GT 445M having 146 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 445M delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce G 102M.

The GT 445M transistor size technology is 25 nm (nanometers) smaller than the GeForce G 102M. This means that the GT 445M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce G 102M.

The GeForce GT 445M v2 requires 35 Watts to run and the GeForce G 102M requires 14 Watts. The GT 445M requires 21 Watts more than the GeForce G 102M to run. The difference is not significant enough for the GT 445M to have a noticeably larger impact on your yearly electricity bills than the GeForce G 102M.
