GeForce GTX 470 -With fourteen tessellation engines, 448 CUDA cores, and 1GB of memory, the GeForce GTX 470 delivers excellent performance in DirectX 11 games such as Metro 2033.
Radeon HD 7970 GPU offers graphics bliss with other advanced innovations including 28nm GCN (Graphic Core Next) architecture, Next Generation Eyefinity Technology, HD3D technology, AMD ZeroCore Power technology and more. Dual-X thermal solution delivers optimal cooling performance and ensures stable performance even when battle heats up.
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7970 Crossfire are massively better than the Nvidia GeForce GTX 470.
The HD 7970 has a 318 MHz higher core clock speed and 200 more Texture Mapping Units than the GeForce GTX 470. This results in the HD 7970 providing 202.8 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 HD 7970 has a 318 MHz higher core clock speed and 24 more Render Output Units than the GeForce GTX 470. This results in the HD 7970 providing 34.9 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 7970 was released over a year more recently than the GeForce GTX 470, and so the HD 7970 is likely to have better driver support, meaning it will be more optimized for running the latest games.
The HD 7970 has 4864 MB more video memory than the GeForce GTX 470, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7970 also has superior memory performance overall.
The HD 7970 has 394.1 GB/sec greater memory bandwidth than the GeForce GTX 470, which means that the memory performance of the HD 7970 is massively better than the GeForce GTX 470.
The Radeon HD 7970 Crossfire has 4096 Shader Processing Units and the GeForce GTX 470 has 448. However, the actual shader performance of the HD 7970 is 2662.4 and the actual shader performance of the GeForce GTX 470 is 896. The HD 7970 having 1766.4 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7970 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTX 470.
The HD 7970 transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 470. This means that the HD 7970 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 470.
The Radeon HD 7970 Crossfire requires 460 Watts to run and the GeForce GTX 470 requires 215 Watts. We would recommend a PSU with at least 550 Watts for the GeForce GTX 470, but we do not have a recommended PSU wattage for the HD 7970. The HD 7970 requires 245 Watts more than the GeForce GTX 470 to run. The difference is significant enough that the HD 7970 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GTX 470.
