In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 510 Desktop are significantly better than the AMD Radeon R5 235.

The Radeon R5 235 has a 425 MHz higher core clock speed and the same number of Texture Mapping Units as the Graphics 510. This results in the Radeon R5 235 providing 3.4 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 235 has a 425 MHz higher core clock speed than the Graphics 510 and the same number of Render Output Units. This results in the Radeon R5 235 providing 1.7 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 510 was released over a year more recently than the Radeon R5 235, and so the Graphics 510 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon R5 235.

The Radeon R5 235 has 1024 MB video memory, but the Graphics 510 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics 510 Desktop has 12 Shader Processing Units and the Radeon R5 235 has 160. However, the actual shader performance of the Graphics 510 is 101 and the actual shader performance of the Radeon R5 235 is 62. The Graphics 510 having 39 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 510 delivers a slightly smoother and more efficient experience when processing graphical data than the Radeon R5 235.

The Graphics 510 transistor size technology is 26 nm (nanometers) smaller than the Radeon R5 235. This means that the Graphics 510 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon R5 235.

The HD Graphics 510 Desktop requires 47 Watts to run and the Radeon R5 235 requires 35 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 510 and a PSU with at least 350 Watts for the Radeon R5 235. The Graphics 510 requires 12 Watts more than the Radeon R5 235 to run. The difference is not significant enough for the Graphics 510 to have a noticeably larger impact on your yearly electricity bills than the Radeon R5 235.
