In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4600 Desktop are significantly better than the AMD Radeon HD 8370D.

The Radeon HD 8370D has a 360 MHz higher core clock speed and 20 more Texture Mapping Units than the Graphics 4600. This results in the Radeon HD 8370D providing 16.6 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 Radeon HD 8370D has a 360 MHz higher core clock speed and 6 more Render Output Units than the Graphics 4600. This results in the Radeon HD 8370D providing 5.3 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 Radeon HD 8370D was released less than a year after the Graphics 4600, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 8370D 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 8370D has 8.5 GB/sec greater memory bandwidth than the Graphics 4600, which means that the memory performance of the Radeon HD 8370D is marginally better than the Graphics 4600.

The Radeon HD 8370D has 128 Shader Processing Units and the HD Graphics 4600 Desktop has 20. However, the actual shader performance of the Radeon HD 8370D is 54 and the actual shader performance of the Graphics 4600 is 100. The Graphics 4600 having 46 better shader performance is not particularly notable, as altogether the Radeon HD 8370D performs better when taking into account other relevant data.

The Graphics 4600 transistor size technology is 18 nm (nanometers) smaller than the Radeon HD 8370D. This means that the Graphics 4600 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 8370D.

The Radeon HD 8370D requires 65 Watts to run and the HD Graphics 4600 Desktop requires 88 Watts. We would recommend a PSU with at least 450 Watts for the Radeon HD 8370D and a PSU with at least 300 Watts for the Graphics 4600. The Graphics 4600 requires 23 Watts more than the Radeon HD 8370D to run. The difference is not significant enough for the Graphics 4600 to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 8370D.
