In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 6700K are significantly better than the Nvidia GeForce GT 630 EVGA 1GB Edition.

The GT 630 has a 460 MHz higher core clock speed and the same number of Texture Mapping Units as the HD i7 6700K. This results in the GT 630 providing 7.4 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 GT 630 has a 460 MHz higher core clock speed but 4 fewer Render Output Units than the HD i7 6700K. The lower ROP count doesn't matter, though, as altogether the GT 630 manages to provide 0.4 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 GT 630, 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 GT 630 when running the latest games.

The GT 630 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 GeForce GT 630 EVGA 1GB Edition has 96 Shader Processing Units and the HD i7 6700K has 24. However, the actual shader performance of the GT 630 is 156 and the actual shader performance of the HD i7 6700K is 221. The HD i7 6700K having 65 better shader performance and an altogether better performance when taking into account other relevant data means that the HD i7 6700K delivers a marginally smoother and more efficient experience when processing graphical data than the GT 630.

The HD i7 6700K transistor size technology is 26 nm (nanometers) smaller than the GT 630. This means that the HD i7 6700K is expected to run slightly cooler and achieve higher clock frequencies than the GT 630.

The GeForce GT 630 EVGA 1GB Edition requires 65 Watts to run and the HD i7 6700K requires 91 Watts. We would recommend a PSU with at least 350 Watts for the GT 630 and a PSU with at least 300 Watts for the HD i7 6700K. The HD i7 6700K requires 26 Watts more than the GT 630 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 GT 630.
