In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 735M are significantly better than the Nvidia GeForce GT 550M 2GB.

The GT 550M has a 165 MHz higher core clock speed than the GeForce GT 735M, but the GeForce GT 735M has 16 more Texture Mapping Units than the GT 550M. As a result, the GeForce GT 735M exhibits a 6.6 GTexel/s better Texture Fill Rate than the GT 550M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 550M has a 165 MHz higher core clock speed than the GeForce GT 735M, but the GeForce GT 735M has 12 more Render Output Units than the GT 550M. As a result, the GeForce GT 735M exhibits a 6.2 GPixel/s better Pixel Fill Rate than the GT 550M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 735M was released over a year more recently than the GT 550M, and so the GeForce GT 735M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 550M.

The GeForce GT 735M and the GeForce GT 550M 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GT 550M has 14.4 GB/sec greater memory bandwidth than the GeForce GT 735M, which means that the memory performance of the GT 550M is slightly better than the GeForce GT 735M.

The GeForce GT 735M has 384 Shader Processing Units and the GeForce GT 550M 2GB has 96. However, the actual shader performance of the GeForce GT 735M is 361 and the actual shader performance of the GT 550M is 142. The GeForce GT 735M having 219 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 735M delivers a marginally smoother and more efficient experience when processing graphical data than the GT 550M.

The GeForce GT 735M transistor size technology is 12 nm (nanometers) smaller than the GT 550M. This means that the GeForce GT 735M is expected to run slightly cooler and achieve higher clock frequencies than the GT 550M.

The GeForce GT 735M requires 17 Watts to run and the GeForce GT 550M 2GB requires 35 Watts. The GT 550M requires 18 Watts more than the GeForce GT 735M to run. The difference is not significant enough for the GT 550M to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 735M.
