Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780M are massively better than the Nvidia GeForce GT 735M.

The GeForce GT 735M has a 118 MHz higher core clock speed than the GeForce GTX 780M, but the GeForce GTX 780M has 96 more Texture Mapping Units than the GeForce GT 735M. As a result, the GeForce GTX 780M exhibits a 70.3 GTexel/s better Texture Fill Rate than the GeForce GT 735M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GT 735M has a 118 MHz higher core clock speed than the GeForce GTX 780M, but the GeForce GTX 780M has 16 more Render Output Units than the GeForce GT 735M. As a result, the GeForce GTX 780M exhibits a 10.5 GPixel/s better Pixel Fill Rate than the GeForce GT 735M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GTX 780M was released less than a year after the GeForce GT 735M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 780M has 2048 MB more video memory than the GeForce GT 735M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 780M also has superior memory performance overall.

The GeForce GTX 780M has 144 GB/sec greater memory bandwidth than the GeForce GT 735M, which means that the memory performance of the GeForce GTX 780M is massively better than the GeForce GT 735M.

The GeForce GT 735M has 384 Shader Processing Units and the GeForce GTX 780M has 1536. However, the actual shader performance of the GeForce GT 735M is 341 and the actual shader performance of the GeForce GTX 780M is 1224. The GeForce GTX 780M having 883 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 780M delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GT 735M.

The GeForce GT 735M requires 17 Watts to run and the GeForce GTX 780M requires 122 Watts. The GeForce GTX 780M requires 105 Watts more than the GeForce GT 735M to run. The difference is significant enough that the GeForce GTX 780M may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 735M.

GPU Mini Review

Mini ReviewGeForce GT 735M is a middle-class GFX, based on the 2013, 28nm, Kepler 2.0 architecture.
It's Based on the Kepler GK208 Core and offers 384 Shader Processing Unit, 32 TMUs and 16 ROPs, on a 64-bit memory interface of standard DDR3. The central unit runs at 889MHz (up to XXXX in Turbo) and the memory clock operates at up to 1000MHz.
Therefore, GeForce GT 735M performs worse than previous in series GeForce GT 730M, especially in common laptop resolutions (1366x768). Its power consumption is, however, much lower.
GeForce GTX 780M is a high-end mobile graphics card based on the 28nm, Kepler architecture.
It's based on the Kepler GK104 Core and offers an identical core configuration to the desktop, flagship, GeForce GTX 680. Therefore, it offers 1536 Shader Processing Units, 128 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5.
While the central unit runs at 771MHz and goes up to 797MHz, in Turbo Mode, the memory clock operates at 1250MHz. Its power consumption is way over 100W and thus only suited for extremely large notebooks.
Its performance is not comparable to the desktop GeForce GTX 680 but rather with GeForce GTX 660 Ti, due to being underclocked.
Paired with a strong Quad Core, even the most demanding games will run at the highest settings, using a 1080p resolution.
GeForce GTX 780M is the fastest single mobile graphics card, as of June 2013.
