In terms of overall gaming performance, the graphical capabilities of the Graphics 510 and the HD i7 4790K are equal.

The Graphics 510 and the HD i7 4790K have the same core clock speed of 350 MHz, but the Graphics 510 has 4 more Texture Mapping Units than the HD i7 4790K. As a result, the Graphics 510 exhibits a 1.4 GTexel/s better Texture Fill Rate than the HD i7 4790K. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Graphics 510 and the HD i7 4790K have the same core clock speed of 350 MHz, but the Graphics 510 has 2 more Render Output Units than the HD i7 4790K. As a result, the Graphics 510 exhibits a 0.7 GPixel/s better Pixel Fill Rate than the HD i7 4790K. 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 HD i7 4790K, 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 HD i7 4790K.

The HD Graphics 510 Desktop and the HD i7 4790K have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Graphics 510 has 8.5 GB/sec greater memory bandwidth than the HD i7 4790K, which means that the memory performance of the Graphics 510 is marginally better than the HD i7 4790K.

The HD Graphics 510 Desktop has 12 Shader Processing Units and the HD i7 4790K has 20. However, the actual shader performance of the Graphics 510 is 101 and the actual shader performance of the HD i7 4790K is 100. The Graphics 510 having 1 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 510 delivers a marginally smoother and more efficient experience when processing graphical data than the HD i7 4790K.

The Graphics 510 transistor size technology is 8 nm (nanometers) smaller than the HD i7 4790K. This means that the Graphics 510 is expected to run very slightly cooler and achieve higher clock frequencies than the HD i7 4790K. While they exhibit similar graphical performance, the Graphics 510 should consume less power than the HD i7 4790K.

The HD Graphics 510 Desktop requires 47 Watts to run and the HD i7 4790K requires 88 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 510 and a PSU with at least 300 Watts for the HD i7 4790K. The HD i7 4790K requires 41 Watts more than the Graphics 510 to run. The difference is significant enough that the HD i7 4790K may have a slight adverse affect on your yearly electricity bills in comparison to the Graphics 510.
