In terms of overall gaming performance, the graphical capabilities of the HD i7 6700K and the Graphics 530 are equal.

The HD i7 6700K and the Graphics 530 have both the same core clock speed and the same Texture Fill Rate. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD i7 6700K and the Graphics 530 have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the HD i7 6700K and the HD Graphics 530 Desktop were released at the same time, so are likely to be quite similar.

The HD i7 6700K and the HD Graphics 530 Desktop have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the HD i7 6700K and the HD Graphics 530 Desktop are the same, which means the HD i7 6700K and the Graphics 530 have equal limitations when it comes to graphical data transfer.

Both the HD i7 6700K and the HD Graphics 530 Desktop have 24 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, the two GPUs have extremely similar stats, so any gaming performance difference would most likely be negligible.

The HD i7 6700K requires 91 Watts to run and the HD Graphics 530 Desktop requires 91 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 6700K and a PSU with at least 300 Watts for the Graphics 530. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
