In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 PNY 2GB Edition are massively better than the AMD Radeon HD 4870 PowerColor PCS+ 512MB Edition.

The GTX 670 has a 135 MHz higher core clock speed and 72 more Texture Mapping Units than the HD 4870. This results in the GTX 670 providing 71.3 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 670 has a 135 MHz higher core clock speed and 16 more Render Output Units than the HD 4870. This results in the GTX 670 providing 16.8 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 670 was released over three years more recently than the HD 4870, and so the GTX 670 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4870 when running the latest games.

The GTX 670 has 1536 MB more video memory than the HD 4870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 670 also has superior memory performance overall.

The GTX 670 has 70.7 GB/sec greater memory bandwidth than the HD 4870, which means that the memory performance of the GTX 670 is much better than the HD 4870.

The Radeon HD 4870 PowerColor PCS+ 512MB Edition has 800 Shader Processing Units and the GeForce GTX 670 PNY 2GB Edition has 1344. However, the actual shader performance of the HD 4870 is 437 and the actual shader performance of the GTX 670 is 1317. The GTX 670 having 880 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 670 delivers a massively smoother and more efficient experience when processing graphical data than the HD 4870.

The GTX 670 transistor size technology is 27 nm (nanometers) smaller than the HD 4870. This means that the GTX 670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4870.

The Radeon HD 4870 PowerColor PCS+ 512MB Edition requires 150 Watts to run and the GeForce GTX 670 PNY 2GB Edition requires 170 Watts. We would recommend a PSU with at least 500 Watts for the HD 4870 and a PSU with at least 500 Watts for the GTX 670. The GTX 670 requires 20 Watts more than the HD 4870 to run. The difference is not significant enough for the GTX 670 to have a noticeably larger impact on your yearly electricity bills than the HD 4870.
