In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4730 PowerColor PCS Edition are noticeably better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The GT 730 and the HD 4730 have the same core clock speed of 700 MHz, but the HD 4730 has 16 more Texture Mapping Units than the GT 730. As a result, the HD 4730 exhibits a 11.2 GTexel/s better Texture Fill Rate than the GT 730. 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 and the HD 4730 have the same core clock speed of 700 MHz, but the HD 4730 has 4 more Render Output Units than the GT 730. As a result, the HD 4730 exhibits a 2.8 GPixel/s better Pixel Fill Rate than the GT 730. 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 three years more recently than the HD 4730, and so the GT 730 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4730 when running the latest games.

The GT 730 has 1536 MB more video memory than the HD 4730, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 4730 has superior memory performance.

The HD 4730 has 28.8 GB/sec greater memory bandwidth than the GT 730, which means that the memory performance of the HD 4730 is slightly better than the GT 730.

The GeForce GT 730 v3 Gigabyte 2GB Edition has 96 Shader Processing Units and the Radeon HD 4730 PowerColor PCS Edition has 640. However, the actual shader performance of the GT 730 is 134 and the actual shader performance of the HD 4730 is 291. The HD 4730 having 157 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4730 delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 730.

The GT 730 transistor size technology is 15 nm (nanometers) smaller than the HD 4730. This means that the GT 730 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4730.

The GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts to run but there is no entry for the Radeon HD 4730 PowerColor PCS Edition. We would recommend a PSU with at least 300 Watts for the GT 730 and a PSU with at least 450 Watts for the HD 4730. The HD 4730 has been recommended a PSU with 150 Watts more than the GT 730. The difference is significant enough that the HD 4730 may have an adverse affect on your yearly electricity bills in comparison to the GT 730.
