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 DirectCU II OC Edition.

The HD 7870 has a 20 MHz higher core clock speed and 48 more Texture Mapping Units than the GTX 670. This results in the HD 7870 providing 50.2 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 20 MHz higher core clock speed and 32 more Render Output Units than the GTX 670. This results in the HD 7870 providing 32.6 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 GeForce GTX 670 DirectCU II OC Edition has 1344 Shader Processing Units and the Radeon HD 7870 Crossfire has 2560. However, the actual shader performance of the GTX 670 is 1422 and the actual shader performance of the HD 7870 is 2176. The HD 7870 having 754 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 but there is no entry for the GTX 670. We would recommend a PSU with at least 600 Watts for the HD 7870, but we do not have a recommended PSU wattage for the GTX 670.

GPU Mini Review

Mini ReviewGeForce GTX 670 DirectCU II OC Edition is a Special Edition of the powerful GeForce GTX 670. See the standard version for more information about it.
The new features include an increase in the core-clock that went from 915MHz to 980MHz while the Turbo Boost is now of 1058MHz. A 20% more effective cooler is also included.
The performance boost is significant and around 5% when compared to the standard GTX 670.
Most demanding games will run at the highest settings.
Radeon 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.
