In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 6700K are significantly better than the AMD Radeon HD 7670A.

The Radeon HD 7670A has a 250 MHz higher core clock speed and 8 more Texture Mapping Units than the HD i7 6700K. This results in the Radeon HD 7670A providing 8.8 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 HD 7670A has a 250 MHz higher core clock speed than the HD i7 6700K and the same number of Render Output Units. This results in the Radeon HD 7670A providing 2 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 Radeon HD 7670A, 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 Radeon HD 7670A when running the latest games.

The Radeon HD 7670A 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 7670A has 480. However, the actual shader performance of the HD i7 6700K is 221 and the actual shader performance of the Radeon HD 7670A is 187. The HD i7 6700K having 34 better shader performance is not particularly notable, as altogether the Radeon HD 7670A performs better when taking into account other relevant data.

The HD i7 6700K transistor size technology is 26 nm (nanometers) smaller than the Radeon HD 7670A. This means that the HD i7 6700K is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 7670A.

The HD i7 6700K requires 91 Watts to run and the Radeon HD 7670A requires 45 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 6700K. The HD i7 6700K requires 46 Watts more than the Radeon HD 7670A to run. The difference is significant enough that the HD i7 6700K may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon HD 7670A.
