In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 730M v2 are noticeably better than the Nvidia GeForce GT 550M 2GB.

The GT 550M has a 21 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 730M. This results in the GT 550M providing 0.3 GTexel/s better texturing performance. 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 21 MHz higher core clock speed than the GT 730M, but the GT 730M has 4 more Render Output Units than the GT 550M. As a result, the GT 730M exhibits a 2.8 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 GT 730M was released over three years more recently than the GT 550M, and so the GT 730M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GT 550M when running the latest games.

The GeForce GT 730M v2 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 memory bandwidth of the GeForce GT 730M v2 and the GeForce GT 550M 2GB are the same, which means the GT 730M and the GT 550M have equal limitations when it comes to graphical data transfer.

The GeForce GT 730M v2 has 384 Shader Processing Units and the GeForce GT 550M 2GB has 96. However, the actual shader performance of the GT 730M is 336 and the actual shader performance of the GT 550M is 142. The GT 730M having 194 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 730M delivers a marginally smoother and more efficient experience when processing graphical data than the GT 550M.

The GT 730M transistor size technology is 12 nm (nanometers) smaller than the GT 550M. This means that the GT 730M is expected to run slightly cooler and achieve higher clock frequencies than the GT 550M.

The GeForce GT 730M v2 requires 33 Watts to run and the GeForce GT 550M 2GB requires 35 Watts. The GT 550M requires 2 Watts more than the GT 730M 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 GT 730M.
