In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics Mobile (Broadwell) are massively better than the AMD Radeon HD 8180.

The Graphics Mobile has a 75 MHz higher core clock speed than the Radeon HD 8180, but the Radeon HD 8180 has 4 more Texture Mapping Units than the Graphics Mobile. As a result, the Radeon HD 8180 exhibits a 0.6 GTexel/s better Texture Fill Rate than the Graphics Mobile. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Graphics Mobile has a 75 MHz higher core clock speed than the Radeon HD 8180, but the Radeon HD 8180 has 2 more Render Output Units than the Graphics Mobile. As a result, the Radeon HD 8180 exhibits a 0.3 GPixel/s better Pixel Fill Rate than the Graphics Mobile. 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 a year more recently than the Radeon HD 8180, and so the Graphics Mobile is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 8180.

The HD Graphics Mobile (Broadwell) and the Radeon HD 8180 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Graphics Mobile has 8.5 GB/sec greater memory bandwidth than the Radeon HD 8180, which means that the memory performance of the Graphics Mobile is marginally better than the Radeon HD 8180.

The HD Graphics Mobile (Broadwell) has 12 Shader Processing Units and the Radeon HD 8180 has 128. However, the actual shader performance of the Graphics Mobile is 10 and the actual shader performance of the Radeon HD 8180 is 19. The Radeon HD 8180 having 9 better shader performance is not particularly notable, as altogether the Graphics Mobile performs better when taking into account other relevant data.

The Graphics Mobile transistor size technology is 6 nm (nanometers) smaller than the Radeon HD 8180. This means that the Graphics Mobile is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon HD 8180.

The HD Graphics Mobile (Broadwell) requires 4 Watts to run and the Radeon HD 8180 requires 4 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.
