In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition are significantly better than the Intel HD i7 3770.

The GT 730 has a 50 MHz higher core clock speed and 12 more Texture Mapping Units than the HD i7 3770. This results in the GT 730 providing 8.6 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 730 has a 50 MHz higher core clock speed than the HD i7 3770 and the same number of Render Output Units. This results in the GT 730 providing 0.2 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 GT 730 was released over a year more recently than the HD i7 3770, and so the GT 730 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD i7 3770.

The GT 730 has 2048 MB video memory, but the HD i7 3770 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce GT 730 v3 Gigabyte 2GB Edition has 96 Shader Processing Units and the HD i7 3770 has 16. However, the actual shader performance of the GT 730 is 134 and the actual shader performance of the HD i7 3770 is 74. The GT 730 having 60 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 730 delivers a marginally smoother and more efficient experience when processing graphical data than the HD i7 3770.

The HD i7 3770 transistor size technology is 18 nm (nanometers) smaller than the GT 730. This means that the HD i7 3770 is expected to run slightly cooler and achieve higher clock frequencies than the GT 730.

The GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts to run and the HD i7 3770 requires 77 Watts. We would recommend a PSU with at least 300 Watts for the GT 730 and a PSU with at least 300 Watts for the HD i7 3770. The HD i7 3770 requires 28 Watts more than the GT 730 to run. The difference is not significant enough for the HD i7 3770 to have a noticeably larger impact on your yearly electricity bills than the GT 730.
