In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7730 v2 Sapphire 2GB Edition are noticeably better than the Nvidia GeForce GT 630 Gigabyte 2GB Edition.

The GT 630 has a 10 MHz higher core clock speed than the HD 7730, but the HD 7730 has 8 more Texture Mapping Units than the GT 630. As a result, the HD 7730 exhibits a 6.2 GTexel/s better Texture Fill Rate than the GT 630. 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 10 MHz higher core clock speed than the HD 7730, but the HD 7730 has 4 more Render Output Units than the GT 630. As a result, the HD 7730 exhibits a 3.2 GPixel/s better Pixel Fill Rate than the GT 630. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7730 was released less than a year after the GT 630, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 630 Gigabyte 2GB Edition and the Radeon HD 7730 v2 Sapphire 2GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7730 has 3.2 GB/sec greater memory bandwidth than the GT 630, which means that the memory performance of the HD 7730 is marginally better than the GT 630.

The GeForce GT 630 Gigabyte 2GB Edition has 96 Shader Processing Units and the Radeon HD 7730 v2 Sapphire 2GB Edition has 384. However, the actual shader performance of the GT 630 is 156 and the actual shader performance of the HD 7730 is 261. The HD 7730 having 105 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7730 delivers a marginally smoother and more efficient experience when processing graphical data than the GT 630.

The HD 7730 transistor size technology is 12 nm (nanometers) smaller than the GT 630. This means that the HD 7730 is expected to run slightly cooler and achieve higher clock frequencies than the GT 630.

The GeForce GT 630 Gigabyte 2GB Edition requires 65 Watts to run and the Radeon HD 7730 v2 Sapphire 2GB Edition requires 47 Watts. We would recommend a PSU with at least 350 Watts for the GT 630 and a PSU with at least 400 Watts for the HD 7730. The GT 630 requires 18 Watts more than the HD 7730 to run. The difference is not significant enough for the GT 630 to have a noticeably larger impact on your yearly electricity bills than the HD 7730.

GPU Mini Review

Mini ReviewOverview
GeForce GT 630 Gigabyte 2GB Edition is a special edition of NVIDIA's Middle-Class GeForce GT 630, created by Gigabyte.

Overclock: Central Unit
The Central Unit Remains the Same.

Overclock: Memory Clock
The Operating Memory Clock runs at 800MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System has been replaced by Gigabyte's custom-designed 80 mm cooler, with air flow optimized cover and aluminum base. The cooler can dissipate heat effectively from the GPU while keeping the fan at lower speed and noise.

Performance
Without Any Overclock Out of The Box, GeForce GT 630 Gigabyte 2GB Edition is as fast as the reference GeForce GT 630.
