In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8650G are significantly better than the Intel HD Graphics 4600 Desktop.

The Radeon HD 8650G has a 133 MHz higher core clock speed and 20 more Texture Mapping Units than the Graphics 4600. This results in the Radeon HD 8650G providing 11.2 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 Radeon HD 8650G has a 133 MHz higher core clock speed and 6 more Render Output Units than the Graphics 4600. This results in the Radeon HD 8650G providing 3.5 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 4600 was released less than a year after the Radeon HD 8650G, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 8650G 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 Radeon HD 8650G has 4.3 GB/sec greater memory bandwidth than the Graphics 4600, which means that the memory performance of the Radeon HD 8650G is marginally better than the Graphics 4600.

The Radeon HD 8650G has 384 Shader Processing Units and the HD Graphics 4600 Desktop has 20. However, the actual shader performance of the Radeon HD 8650G is 276 and the actual shader performance of the Graphics 4600 is 100. The Radeon HD 8650G having 176 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8650G delivers a slightly smoother and more efficient experience when processing graphical data than the Graphics 4600.

The Graphics 4600 transistor size technology is 10 nm (nanometers) smaller than the Radeon HD 8650G. This means that the Graphics 4600 is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon HD 8650G.

The Radeon HD 8650G requires 35 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 8650G. The Graphics 4600 requires 53 Watts more than the Radeon HD 8650G 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 8650G.
