In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 Palit JetStream 4GB Edition are massively better than the Nvidia GeForce GT 930 2GB.

The GT 930 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GT 930 was released over a year more recently than the GTX 980, and so the GT 930 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 980.

The GTX 980 has 2048 MB more video memory than the GT 930, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 980 also has superior memory performance overall.

The GTX 980 has 208.4 GB/sec greater memory bandwidth than the GT 930, which means that the memory performance of the GTX 980 is massively better than the GT 930.

The GeForce GTX 980 Palit JetStream 4GB Edition has 2048 Shader Processing Units and the GeForce GT 930 2GB has 384. However, the actual shader performance of the GTX 980 is 3362 and the actual shader performance of the GT 930 is 0. The GTX 980 having 3362 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a massively smoother and more efficient experience when processing graphical data than the GT 930.

The GeForce GTX 980 Palit JetStream 4GB Edition requires 180 Watts to run and the GeForce GT 930 2GB requires 35 Watts. We would recommend a PSU with at least 500 Watts for the GTX 980 and a PSU with at least 300 Watts for the GT 930. The GTX 980 requires 145 Watts more than the GT 930 to run. The difference is significant enough that the GTX 980 may have an adverse affect on your yearly electricity bills in comparison to the GT 930.
