In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4600 Desktop are massively better than the AMD Radeon HD 6250.

The Graphics 4600 has a 120 MHz higher core clock speed than the Radeon HD 6250, but the Radeon HD 6250 has 4 more Texture Mapping Units than the Graphics 4600. As a result, the Radeon HD 6250 exhibits a 0.6 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 120 MHz higher core clock speed than the Radeon HD 6250, but the Radeon HD 6250 has 2 more Render Output Units than the Graphics 4600. As a result, the Radeon HD 6250 exhibits a 0.3 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 over a year more recently than the Radeon HD 6250, and so the Graphics 4600 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 6250.

The Radeon HD 6250 has 256 MB video memory, but the Graphics 4600 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics 4600 Desktop has 20 Shader Processing Units and the Radeon HD 6250 has 80. However, the actual shader performance of the Graphics 4600 is 100 and the actual shader performance of the Radeon HD 6250 is 15. The Graphics 4600 having 85 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 4600 delivers a noticeably smoother and more efficient experience when processing graphical data than the Radeon HD 6250.

The Graphics 4600 transistor size technology is 18 nm (nanometers) smaller than the Radeon HD 6250. This means that the Graphics 4600 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6250.

The HD Graphics 4600 Desktop requires 88 Watts to run and the Radeon HD 6250 requires 9 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 4600. The Graphics 4600 requires 79 Watts more than the Radeon HD 6250 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 6250.
