In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 6700K are very slightly better than the AMD Radeon HD 5670 Gigabyte 1GB OC Edition.

The HD 5670 has a 600 MHz higher core clock speed and 4 more Texture Mapping Units than the HD i7 6700K. This results in the HD 5670 providing 13.4 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 HD 5670 has a 600 MHz higher core clock speed than the HD i7 6700K and the same number of Render Output Units. This results in the HD 5670 providing 4.8 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 three years more recently than the HD 5670, and so the HD i7 6700K is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5670 when running the latest games.

The HD 5670 has 1024 MB video memory, but the HD i7 6700K does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i7 6700K has 24 Shader Processing Units and the Radeon HD 5670 Gigabyte 1GB OC Edition has 400. However, the actual shader performance of the HD i7 6700K is 221 and the actual shader performance of the HD 5670 is 190. The HD i7 6700K having 31 better shader performance is not particularly notable, as altogether the HD 5670 performs better when taking into account other relevant data.

The HD i7 6700K transistor size technology is 26 nm (nanometers) smaller than the HD 5670. This means that the HD i7 6700K is expected to run slightly cooler and achieve higher clock frequencies than the HD 5670. While they exhibit similar graphical performance, the HD i7 6700K should consume less power than the HD 5670.

The HD i7 6700K requires 91 Watts to run but there is no entry for the Radeon HD 5670 Gigabyte 1GB OC Edition. We would recommend a PSU with at least 300 Watts for the HD i7 6700K.
