In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro FX 1800M are marginally better than the Intel HD Graphics Mobile (Broadwell).

The Graphics Mobile was released over three years more recently than the Quadro FX 1800M, and so the Graphics Mobile is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Quadro FX 1800M when running the latest games.

The Quadro FX 1800M has 1024 MB video memory, but the Graphics Mobile does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics Mobile (Broadwell) has 12 Shader Processing Units and the Quadro FX 1800M has 72. However, the actual shader performance of the Graphics Mobile is 10 and the actual shader performance of the Quadro FX 1800M is 40. The Quadro FX 1800M having 30 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro FX 1800M delivers a noticeably smoother and more efficient experience when processing graphical data than the Graphics Mobile.

The Graphics Mobile transistor size technology is 18 nm (nanometers) smaller than the Quadro FX 1800M. This means that the Graphics Mobile is expected to run slightly cooler and achieve higher clock frequencies than the Quadro FX 1800M. While they exhibit similar graphical performance, the Graphics Mobile should consume less power than the Quadro FX 1800M.

The HD Graphics Mobile (Broadwell) requires 4 Watts to run and the Quadro FX 1800M requires 45 Watts. The Quadro FX 1800M requires 41 Watts more than the Graphics Mobile to run. The difference is significant enough that the Quadro FX 1800M may have a slight adverse affect on your yearly electricity bills in comparison to the Graphics Mobile.
