In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4600 Desktop are massively better than the AMD Radeon HD 8180.

The Graphics 4600 has a 175 MHz higher core clock speed than the Radeon HD 8180, but the Radeon HD 8180 has 4 more Texture Mapping Units than the Graphics 4600. As a result, the Radeon HD 8180 exhibits a 0.2 GTexel/s better Texture Fill Rate than the Graphics 4600. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Graphics 4600 has a 175 MHz higher core clock speed than the Radeon HD 8180, but the Radeon HD 8180 has 2 more Render Output Units than the Graphics 4600. As a result, the Radeon HD 8180 exhibits a 0.1 GPixel/s better Pixel Fill Rate than the Graphics 4600. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Graphics 4600 was released less than a year after the Radeon HD 8180, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 8180 and the HD Graphics 4600 Desktop have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Graphics 4600 has 8.5 GB/sec greater memory bandwidth than the Radeon HD 8180, which means that the memory performance of the Graphics 4600 is marginally better than the Radeon HD 8180.

The Radeon HD 8180 has 128 Shader Processing Units and the HD Graphics 4600 Desktop has 20. However, the actual shader performance of the Radeon HD 8180 is 19 and the actual shader performance of the Graphics 4600 is 100. The Graphics 4600 having 81 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 4600 delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 8180.

The Graphics 4600 transistor size technology is 6 nm (nanometers) smaller than the Radeon HD 8180. This means that the Graphics 4600 is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon HD 8180.

The Radeon HD 8180 requires 4 Watts to run and the HD Graphics 4600 Desktop requires 88 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 4600, but we do not have a recommended PSU wattage for the Radeon HD 8180. The Graphics 4600 requires 84 Watts more than the Radeon HD 8180 to run. The difference is significant enough that the Graphics 4600 may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 8180.
