In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 Crossfire are noticeably better than the Nvidia GeForce GTX 670 PNY 2GB Edition.

The HD 7870 has a 85 MHz higher core clock speed and 48 more Texture Mapping Units than the GTX 670. This results in the HD 7870 providing 57.5 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 7870 has a 85 MHz higher core clock speed and 32 more Render Output Units than the GTX 670. This results in the HD 7870 providing 34.7 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 less than a year after the HD 7870, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The HD 7870 has 2048 MB more video memory than the GTX 670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 also has superior memory performance overall.

The HD 7870 has 114.9 GB/sec greater memory bandwidth than the GTX 670, which means that the memory performance of the HD 7870 is massively better than the GTX 670.

The Radeon HD 7870 Crossfire has 2560 Shader Processing Units and the GeForce GTX 670 PNY 2GB Edition has 1344. However, the actual shader performance of the HD 7870 is 2176 and the actual shader performance of the GTX 670 is 1317. The HD 7870 having 859 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 670.

The Radeon HD 7870 Crossfire requires 350 Watts to run and the GeForce GTX 670 PNY 2GB Edition requires 170 Watts. We would recommend a PSU with at least 600 Watts for the HD 7870 and a PSU with at least 500 Watts for the GTX 670. The HD 7870 requires 180 Watts more than the GTX 670 to run. The difference is significant enough that the HD 7870 may have an adverse affect on your yearly electricity bills in comparison to the GTX 670.

GPU Mini Review

Mini ReviewRadeon HD 7870 Crossfire is a solution of two Radeon HD 7870 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7870 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to 44% better than a single Radeon HD 7870 performing by itself it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7870. Expect this combination to draw up to 350 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
GeForce GTX 670 PNY 2GB Edition is a renamed GeForce GTX 670 with no new features - not even a new cooling system. Its performance is exactly like the reference card.
