In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 6700K are marginally better than the AMD Radeon R7 7600.

The Radeon R7 7600 has a 370 MHz higher core clock speed and 8 more Texture Mapping Units than the HD i7 6700K. This results in the Radeon R7 7600 providing 11.7 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 R7 7600 has a 370 MHz higher core clock speed than the HD i7 6700K and the same number of Render Output Units. This results in the Radeon R7 7600 providing 3 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 HD i7 6700K was released over a year more recently than the Radeon R7 7600, and so the HD i7 6700K is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon R7 7600.

The HD i7 6700K and the Radeon R7 7600 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 Radeon R7 7600 are the same, which means the HD i7 6700K and the Radeon R7 7600 have equal limitations when it comes to graphical data transfer.

The HD i7 6700K has 24 Shader Processing Units and the Radeon R7 7600 has 384. However, the actual shader performance of the HD i7 6700K is 221 and the actual shader performance of the Radeon R7 7600 is 180. The HD i7 6700K having 41 better shader performance is not particularly notable, as altogether the Radeon R7 7600 performs better when taking into account other relevant data.

The HD i7 6700K transistor size technology is 14 nm (nanometers) smaller than the Radeon R7 7600. This means that the HD i7 6700K is expected to run slightly cooler and achieve higher clock frequencies than the Radeon R7 7600. While they exhibit similar graphical performance, the HD i7 6700K should consume less power than the Radeon R7 7600.

The HD i7 6700K requires 91 Watts to run and the Radeon R7 7600 requires 65 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 Radeon R7 7600. The HD i7 6700K requires 26 Watts more than the Radeon R7 7600 to run. The difference is not significant enough for the HD i7 6700K to have a noticeably larger impact on your yearly electricity bills than the Radeon R7 7600.
