In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 920M 2GB are massively better than the Nvidia Quadro FX 380M.

The GeForce 920M 2GB was released over three years more recently than the Quadro FX 380M, and so the GeForce 920M 2GB is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Quadro FX 380M when running the latest games.

The GeForce 920M 2GB has 1536 MB more video memory than the Quadro FX 380M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 920M 2GB also has superior memory performance overall.

The GeForce 920M 2GB has 1.6 GB/sec greater memory bandwidth than the Quadro FX 380M, which means that the memory performance of the GeForce 920M 2GB is marginally better than the Quadro FX 380M.

The GeForce 920M 2GB has 384 Shader Processing Units and the Quadro FX 380M has 16. However, the actual shader performance of the GeForce 920M 2GB is 366 and the actual shader performance of the Quadro FX 380M is 10. The GeForce 920M 2GB having 356 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 920M 2GB delivers a noticeably smoother and more efficient experience when processing graphical data than the Quadro FX 380M.

The GeForce 920M 2GB transistor size technology is 12 nm (nanometers) smaller than the Quadro FX 380M. This means that the GeForce 920M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the Quadro FX 380M.

The GeForce 920M 2GB requires 25 Watts to run and the Quadro FX 380M requires 25 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
