In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 260M are significantly better than the Intel HD Graphics Mobile (Broadwell).

The GeForce GTX 260M has a 250 MHz higher core clock speed and 52 more Texture Mapping Units than the Graphics Mobile. This results in the GeForce GTX 260M providing 29.6 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 GTX 260M has a 250 MHz higher core clock speed and 14 more Render Output Units than the Graphics Mobile. This results in the GeForce GTX 260M providing 8.2 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 Graphics Mobile was released over three years more recently than the GeForce GTX 260M, 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 GeForce GTX 260M when running the latest games.

The GeForce GTX 260M 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 GeForce GTX 260M has 112. However, the actual shader performance of the Graphics Mobile is 10 and the actual shader performance of the GeForce GTX 260M is 154. The GeForce GTX 260M having 144 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 260M delivers a significantly smoother and more efficient experience when processing graphical data than the Graphics Mobile.

The Graphics Mobile transistor size technology is 43 nm (nanometers) smaller than the GeForce GTX 260M. This means that the Graphics Mobile is expected to run much cooler and achieve higher clock frequencies than the GeForce GTX 260M.

The HD Graphics Mobile (Broadwell) requires 4 Watts to run and the GeForce GTX 260M requires 65 Watts. The GeForce GTX 260M requires 61 Watts more than the Graphics Mobile to run. The difference is significant enough that the GeForce GTX 260M may have an adverse affect on your yearly electricity bills in comparison to the Graphics Mobile.
