In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti Gigabyte OC 1GB Edition are massively better than the AMD Radeon HD 4670 AGP.

The GTX 560 Ti has a 150 MHz higher core clock speed and 32 more Texture Mapping Units than the HD 4670. This results in the GTX 560 Ti providing 33.6 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 GTX 560 Ti has a 150 MHz higher core clock speed and 24 more Render Output Units than the HD 4670. This results in the GTX 560 Ti providing 22.8 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 GTX 560 Ti was released over three years more recently than the HD 4670, and so the GTX 560 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4670 when running the latest games.

The GeForce GTX 560 Ti Gigabyte OC 1GB Edition and the Radeon HD 4670 AGP have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 560 Ti has 102.4 GB/sec greater memory bandwidth than the HD 4670, which means that the memory performance of the GTX 560 Ti is massively better than the HD 4670.

The GeForce GTX 560 Ti Gigabyte OC 1GB Edition has 384 Shader Processing Units and the Radeon HD 4670 AGP has 320. However, the actual shader performance of the GTX 560 Ti is 691 and the actual shader performance of the HD 4670 is 168. The GTX 560 Ti having 523 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 560 Ti delivers a massively smoother and more efficient experience when processing graphical data than the HD 4670.

The GTX 560 Ti transistor size technology is 15 nm (nanometers) smaller than the HD 4670. This means that the GTX 560 Ti is expected to run slightly cooler and achieve higher clock frequencies than the HD 4670.

The Radeon HD 4670 AGP requires 59 Watts to run but there is no entry for the GTX 560 Ti. We would recommend a PSU with at least 400 Watts for the HD 4670, but we do not have a recommended PSU wattage for the GTX 560 Ti.
