In terms of overall gaming performance, the graphical capabilities of the Intel G4 900MHz are significantly better than the Nvidia GeForce 940MX 2GB.

The GeForce 940MX 2GB has a 822 MHz higher core clock speed but 24 fewer Texture Mapping Units than the G4 900MHz. The lower TMU count doesn't matter, though, as altogether the GeForce 940MX 2GB manages to provide 12.5 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 GeForce 940MX 2GB has a 822 MHz higher core clock speed and 5 more Render Output Units than the G4 900MHz. This results in the GeForce 940MX 2GB providing 8.1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The G4 900MHz was released over three years more recently than the GeForce 940MX 2GB, and so the G4 900MHz is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 940MX 2GB when running the latest games.

The GeForce 940MX 2GB has 2048 MB video memory, but the G4 900MHz does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the G4 900MHz and the GeForce 940MX 2GB have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 940MX 2GB is 644 and by the G4 900MHz is 644. Knowing that the shader performance of the GeForce 940MX 2GB is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The G4 900MHz transistor size technology is 18 nm (nanometers) smaller than the GeForce 940MX 2GB. This means that the G4 900MHz is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 940MX 2GB.

The G4 900MHz requires 28 Watts to run and the GeForce 940MX 2GB requires 25 Watts. The G4 900MHz requires 3 Watts more than the GeForce 940MX 2GB to run. The difference is not significant enough for the G4 900MHz to have a noticeably larger impact on your yearly electricity bills than the GeForce 940MX 2GB.
