In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R5 7400K are significantly better than the Intel HD Graphics 4600 Desktop.

The Radeon R5 7400K has a 356 MHz higher core clock speed and 12 more Texture Mapping Units than the Graphics 4600. This results in the Radeon R5 7400K providing 10.5 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 R5 7400K has a 356 MHz higher core clock speed and 6 more Render Output Units than the Graphics 4600. This results in the Radeon R5 7400K providing 5.2 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 Radeon R5 7400K was released over a year more recently than the Graphics 4600, and so the Radeon R5 7400K is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Graphics 4600.

The Radeon R5 7400K 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 R5 7400K has 4.3 GB/sec greater memory bandwidth than the Graphics 4600, which means that the memory performance of the Radeon R5 7400K is marginally better than the Graphics 4600.

The Radeon R5 7400K has 256 Shader Processing Units and the HD Graphics 4600 Desktop has 20. However, the actual shader performance of the Radeon R5 7400K is 126 and the actual shader performance of the Graphics 4600 is 100. The Radeon R5 7400K having 26 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R5 7400K delivers a slightly smoother and more efficient experience when processing graphical data than the Graphics 4600.

The Graphics 4600 transistor size technology is 6 nm (nanometers) smaller than the Radeon R5 7400K. This means that the Graphics 4600 is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon R5 7400K.

The Radeon R5 7400K requires 65 Watts to run and the HD Graphics 4600 Desktop requires 88 Watts. We would recommend a PSU with at least 300 Watts for the Radeon R5 7400K and a PSU with at least 300 Watts for the Graphics 4600. The Graphics 4600 requires 23 Watts more than the Radeon R5 7400K 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 R5 7400K.
